BXR 300C BXR, 300R

INTRODUCTION
The Fender BXR 300 AMPLIFIER is the most recent effort in state of the art bass amplifier technology, and is a member of the FENDER BXR series. The design execution of the BXR 300 was carried out with the aid of some of todays best players, and represents years of thought and consideration in the determination of features and specifications. The features included in the BXR 300 will provide a forum for almost every conceivable playing style from contemporary to those yet to come. This manuel covers all the features and functions for both BXR 300 models; the BXR 300R (rack mount) and the BXR 300C (1-15 combo). Much attention has been given to those who would like to take advantage of the new signal processing devices which have appeared in recent time. Processors from simple battery powered devices to professional rack mounted studio types may be used. This facility is accomplished through the use of PREAMP OUT and POWER AMP IN. The preamp section of the BXR 300 features two inputs, of differing sensitivity. A pair of buttons called ENHANCE are provided to allow enhancement of the low or high end of the spectrum. Active BASS and TREBLE controls allow response tailoring of the high and low frequency areas of the sounds you and your instrument produce. The MID and MID FREQUENCY controls allow up to 20 decibels of boost or cut of the mid frequencies from 150 Hz to 4kHz. The rugged 300 Watt power amplifier was designed to give reliable service under all conditions and is equipped with our exclusive DELTACOMP adaptive compression system. When DELTACOMP engages, it is practically impossible to cause the power amplifiers to clip (distort). With DELTACOMP, apparent compressor release time is kept short yet waveform distortion is kept to a minimum at low frequencies. The BXR 300R is designed to perform well with almost any high quality speaker system, but performs best when used with members of the FENDER BXR and HM series. Speakers in these series include the BXR-115 , with a single fifteen inch FENDER special design driver, BXR-215 with two fifteen inch FENDER special design drives, BXR-410 with four ten inch FENDER special design drivers or the BXR SPECTRUM, employing one eighteen inch and two ten inch FENDER special design drivers and a BI-AMP ready crossover network. WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE UNIT TO RAIN OR MOISTURE.

FRONT PANEL DESCRIPTIONS

The front panel contains all items necessary for system operation and observation. Please read this section of the manual carefully to make sure you understand all the operational features of your new Fender BXR 300. The Front Panel is similar for both the 300R and 300C. (A) INPUT: Two inputs are provided; Input 1 - High gain Input 2 - Low gain The high gain input (INPUT 1) should be used for most instruments. This input can handle as much as 3.5 volts R.M.S., while the low gain input (INPUT 2) accepts 7 volts R.M.S. without audible distortion. For both cases this is greater than any active bass with a 9 volt battery can produce. if you are using a bass with dual 9 volt batteries, or a "hot" passive bass it might be wise to try input 2. For the rare case where two players want to use one amplifier, or where two instruments are to be used during the performance, both inputs may be used. (B) ENHANCE: HIGH ENHANCE provides high frequency boost. LOW ENHANCE provides low frequency boost, while eliminating sub-sonic noises below 40 Hz. (C) VOLUME: This control sets the gain of the preamp and serves as an adjustment for the "loudness" of the amplifier. (D) TREBLE: - adjusts the high frequency part of the spectrum. Turning the treble up will cause the sound to become "BRIGHT" or more "CRISP". (E) MID: - Can be used to add or subtract the frequency range set by MID FREQUENCY control. (F) MID FREQUENCY: - Adjusts the frequency of boost or cut by the MID control. (G) BASS - adjusts the low frequency part of spectrum, the area where the "deep" fundamental reside. (H) PREAMP OUT: The preamp jack is a source of signal as it appears at the power amp input. This jack can be used as a "LINE OUT" or as a "SEND" point for an external effects device. (I) POWER AMP IN: Use of this jack allows the default input signal from the preamp to be replaced by an external source, (usually the "return" from an effects device). (J) DELTACOMP: With this button in, DELTACOMP is active, in the out position, DELTACOMP is deactivated, and a special ASYMMETRIC LIMITER circuit is enabled. The LED next to this button indicates that the power amplifier has reached full power and that either DELTACOMP or LIMITING has occurred, depending which position that the switch is in. The unit may seem louder without DELTACOMP since the power amp will be allowed to go into clipping. With DELTACOMP on, your volume level will be rather loud before the compressor turns on; this is normal. (K) POWER: Turns the BXR 300 on or off.

REAR PANEL DESCRIPTIONS

(L) SPEAKER: Speaker connections are four ohms minimum. The two jacks are wired in parallel. The BXR 300 is not designed for speaker impedance lower than 4 ohms total. (M) TWO SPEED FAN: The two speed fan normally runs at low speed, and will automatically go to high speed when things get loud. High speed operation during high level performance is quite OK. If you suddenly reduce your level, the fan speed (if high) may take a while to return to low (normal) speed. Do not block air flow to the rear of the amplifier. (N) POWER RATING: This indicates how much power the amplifier can "draw" from the wall socket when the amplifier is at full power (1200VA). The marking directly below indicates what the wall socket Voltage and frequency must be. Incorrect line voltage will damage your amplifier and VOID THE WARRANTY! (O) LINE CORD: The line cord should be connected to a suitable power source, with the correct voltage and frequency, as shown in the power rating at the amplifier rear (item N above). if your not sure check some other piece of equipment in your area. DO NOT ALTER THE AC PLUG.

SUGGESTED FIRST TIME OPERATION
If this the first time youve used a FENDER BXR 300 we suggest that you try the following first time control setting procedure. Be sure the speaker is connected with a speaker cable (not an instrument cable) and the line cord is plugged into a suitable power source. If you own a BXR 300C, the internal 15 inch speaker will already be connected. Depress the two ENHANCE buttons and turn the VOLUME to zero (7 OCLOCK) and the TREBLE, MID, MID FREQUENCY, and BASS to 0 (12:00 OCLOCK), and DELTACOMP off. With your instrument connected, press the power rocker switch to ON The RED PILOT lamp will illuminate, and the fan in the rear panel will begin to rotate slowly. Advance the volume while playing a few notes on the bass. Experiment with the controls to become familiar with the features that are available to you.

FIGURE 1 is a common connection favored by the bassist who wants extremely high level. it should be noted that two 15 speakers have 50% more cone area than one 18 speaker. FIGURE 2 is an example of two FENDER BXR 410 s connected in parallel. FIGURE 3 shows a BXR 115 and a BXR 410 connected in parallel, which provides a well balanced wide range arrangement. FIGURE 4 illustrates one FENDER BXR SPECTRUM system operating in full range mode. With its 18 woofer, the SPECTRUM is ideal for five string bass.

PARALLEL SPEAKERS

When speakers are connected in parallel, as in the example of FIGURE 1, 2, and 3 above, the impedance of two equal systems will halve. impedance of equal impedance systems will have a new impedance equal to the individual identical impedance divided by the number of systems. The minimum for the FENDER BXR 300 is 4 ohms, there is no maximum (if no speakers are connected, no harm will result).
SETTING UP EXTERNAL SIGNAL PROCESSING
External signal processors may be used as previously described. Devices used with the preamp out, power amp in may be set up as follows: Connect the PREAMP OUT to the input jack of the effects device, and the POWER AMP IN to the output jack of the effects device. Read the owners manual for the device as required. if you get no sound when the device is in the IN mode, you may have the wires to the external device crossed (exchanged) or the device may not be turned on.

MECHANICAL OPTIONS

For those users who will not be rack mounting their BXR 300R we have provided the option of removable rack ears. with the rack ears removed, an optional strap handle kit may be installed. If you should use a handle kit other than FENDER, be sure that the mounting screws protrude no more than 1/2 inch past the mounting plane (underside) of the handle. If you decide at a later time to re-install the rack ears, make sure that you use the same screws that were originally supplied.
SUGGESTED SPEAKER ARRANGEMENTS WITH BXR 300R
There are an almost infinite number of speaker setups possible, what with the variety of speaker systems available. We will attempt to describe four typical situations.

BXR 100 Owners Manual

Congratulations on your purchase of the Fender BXR 100 Bass amplifier. The Fender BXR 100 is the most recent effort in state-of-the-art bass amplifier technology, and is a member of the FENDER BXR series. The design of the BXR 100 was carried out with the aid of some of today's best bass players, and represents years of thought and consideration in determining features and specifications. The features included in the BXR 100 will provide a forum for almost every conceivable playing style, from "traditional" to "contemporary", and those yet to come. The preamp section of the BXR 100 features two inputs of differing sensitivities, allowing for the use of a wide variety of input sources and levels. A MID NOTCH button is provided to enhance the mid frequency response. The 4-band EQ allows for up to 12 decibels of boost or cut in 4 bands between 80 Hz and 6KHz. The PREAMP OUT & POWER AMP IN jacks can be used as an effects loop or send and return points while slaving multiple amps together. A HEADPHONE jack automatically mutes the speaker while driving stereo headphones for private practice sessions. The quasi-balanced LINE OUT jack is used for "hum free" direct connection to recording and sound reinforcement equipment. The rugged power amplifier is designed to give years of reliable service under all conditions. It is equipped with our exclusive DELTACOMP adaptive compressor system. With DELTACOMP, it is practically impossible to clip (distort) the power amplifier. The apparent release time of the compressor is short, yet distortion at low frequencies is kept to a minimum. The BXR 100 incorporates a highly efficient, computerdesigned, turned port cabinet, and delivers a full 100 watts R.M.S. to its single fifteen inch Fender Special Design driver. The selection of a Fender amplifier will reward you with years of quality performance and a wide range of musical sounds. This manual is designed to familiarize you with the equipment and to acquaint you with its many features. Please read it carefully so you will benefit from all the features as soon as you start using the amplifier. The built in quality of a Fender amplifier is the result of over four decades of dedication, and the combined skills of research and development by our engineers and musicians. That is why we proudly say FENDER, The Sound That Creates Legends. WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE
BXR 100 Front Panel Functions
The front panel contains all items necessary for system operation and observation. Please read this section of the manual carefully to make sure you understand all the operational features for your new FENDER BXR 100 bass amplifier. A. INPUT 1 - A high impedance, high sensitivity plug-in connection for instruments. This input can handle as much as 2.5 volts R.M.S., and should be used with most instruments. B. INPUT 2 - Plug-in connection for instruments. This input is recommended for basses with active pickups, and can handle as much as 5 volts R. M. S. C. DEEP switch - boosts and extends the low frequency response of the amplifier. D. NOTCH switch - removes midrange, making the amp sound punchy. This switch is good for thump and pluck playing. E. F. BRIGHT switch - adds high frequency sparkle. GAIN control - adjusts the gain of the preamplifier. This control, in conjunction with the VOLUME control (item ), allows the use of a variety of pickups, from high-impedance
low-level acoustic pickups to high-output active pickups. Lowlevel pickups generally require a high GAIN setting and low VOLUME setting, while hotter pickups require a lower GAIN setting and a higher VOLUME setting. This maximizes headroom and minimizes noise. G. LOW shelving control - adjusts the low part of the frequency spectrum, where the deep fundamentals reside. H. HIGH shelving control - adjusts the high part of the frequency spectrum. Turning up the HIGH control will add sparkle to the sound. 1. GRAPHIC EQUALIZER - allows precise adjustment of the tonal characteristics of the amplifier. Each control provides a 12 dB boost or cut to narrow bands of frequencies centered about 80, 150, 300, 570, 1.1k, 2.1k, and 4kHz. The 80, 150, and 300 Hz controls are used to adjust the low, mid, and high fundamental notes of the bass. The 570, 1.1k, 2.1k, and 4k controls allow control of the timbre of the instrument, allowing for a very wide variety of tonal characteristics.

VOLUME control - adjusts the level of the signal coming out of the pre-amplifier section. This control is used in conjunction with the GAIN control to set the overall sound level of the amplifier. In order to maximize headroom and minimize noise, instruments with low- level pickups will require a high GAIN and low VOLUME setting, while other instruments will require a lower GAIN and higher VOLUME setting. It is recommended that the VOLUME control be set as high as possible for maximum DELTACOMP compressor range. PREAMP OUT jack -This jack provides an unbalanced mono output signal from the preamp. This output can be used with the POWER AMP IN jack (item L) as a patch point for mono effects devices. It can also be used to provide a signal to a recording or sound reinforcement mixer. In addition, this output can be used to drive another BXR 100 used as a slave amp. This is done by connecting a standard guitar cord from the PREAMP OUT jack of the master amplifier to the POWER AMP IN jack (item L) of the slave. POWER AMP IN jack - This unbalanced input goes directly into the power amp. It automatically disconnects the preamp when used. This jack is useful when using the effects loop feature, or when using the BXR 100 as a slave amp.
M. HEADPHONES output jack - This jack allows the use of stereo headphones for private listening. When this jack is used, the internal speaker is disconnected. WARNING: BE CAREFUL WHEN USING HEADPHONES, AS EXCESSIVE VOLUME WILL RUIN YOUR HEARING! N. LINE OUT jack - This quasi-balanced output is derived from the speaker, and is at line level, similar to that of the PREAMP OUT jack (item K). Since the LINE OUT jack is post-power amp, it provides a signal that is affected by the DELTACOMP adaptive compressor. The jack is wired TIP (+), RING (-), and SLEEVE ground. If the LINE OUT jack is used to connect to a balanced input, it will greatly reduce hum caused by a ground loop (a difference in ground potential) between the BXR 100 and another piece of equipment. 0. POWER INDICATOR When this LED is illuminated, the BXR 100 is eceiving power. POWER SWITCH - turns the BXR 100 ON or OFF.

BXR 100 Rear Panel

NOTE: DO NOT BLOCK THE AIR FLOW TO THE REAR PANEL, FOR EXAMPLE, BY BACKING THE AMPLIFIER UP AGAINST A WALL. The rear panel is used to keep the output devices from getting too hot. Should the amplifier overheat, a thermal switch will shut the amplifier off until the output devices cool. POWER CORD - This amplifier is equipped with a grounding type supply cord to reduce the possibility of shock hazard. Be sure to connect it to a grounded AC receptacle. The line cord should be connected to a suitable power source, in accordance with the voltage and frequency as shown by the power rating on the rear panel. If you are not sure, check some other piece of equipment in the area. DO NOT ALTER THE THREE PRONG PLUG.
COVERING CARE The exclusive vinyl covering your cabinet has been especially designed for years of lasting beauty. A very light, soapy solution on a sponge may be used to remove dirt and residue that may accumulate in the texture. Be careful not to let any liquid come in contact with the operating surfaces. UNPLUG THE POWER CORD BEFORE CLEANING.
Troubleshooters Checklist
If the amp is set up but does not function, check the following items: - Is the amp power cord plugged into an electrical outlet? - Is there power at the outlet? - Are all the control knobs turned up? - Is the volume control on the instrument turned up? - Is the instrument properly plugged into the amplifier? (Eliminate any effect pedals and try another guitar cord.) If, after checking all of the above, the system is still not performing correctly, consult your FENDER Service Dealer.
