Carvins F-Series of professional stereo amplifiers represent the state of the art in linear audio power amplification technology. From small clubs to sports arenas youll love the crystal clear sound these amplifiers provide. Their light-weight, compact design is complemented by heavy duty construction perfectly suited for the rigors of road use. Theyre available in three power levels to fit the widest possible range of applications. It all starts with a massive, precision toroidal power transformer. This type of transformer is praised for its efficient transfer of energy and the way it confines noise fields quietly within its coils. With this quiet efficiency also comes lighter weight. One of the main reasons Carvin is able to offer a substantial 1,200 Watts of power from a two rack unit package weighing only 25 pounds. But thats just the beginning. A specially designed cooling chamber funnels the air volume of an average sized refrigerator across the heatsinks every 20 seconds. The heatsink size, shape and configuration are custom made and optimized with the help of computer aided design. The height to width ratio pushes the envelope of aluminum extrusion technology. Our high fin count is the greatest in the industry but even more impressive are the 675 micro-fins which increase the heat transferring surface area of the sink by a phenomenal 52%! Staggered mounting of the power transistors distributes heat evenly across the entire heatsink to eliminate hotspots. Each model in Carvins F-Series has enough thermal headroom to dissipate more than twice its power rating. Carvins F-Series offers high quality audio in a tough, efficient package while providing peace of mind reliability.

MAINTENANCE

Carvins F-Series amplifiers have free-flow ventilation and require no filter maintenance. However, use caution to avoid spilling liquids or allowing any other foreign matter inside the unit. As with all pro-audio gear, avoid prolonged use in caustic environments (i.e., on the beach). When used in such an environment, please be sure the amplifier is adequately protected by rack, covers, etc. To clean the unit, always use a mild detergent and warm water solution applied to a soft cloth. Never spray cleaning products directly on the unit.

Possible Cause

Input signal

Correction

Clip LEDs light to indicate maximum output level. This is not a problem as long as the LEDs dont stay continuously lit and the sound is not distorted. Running the system with the LEDs continuously lit will not harm the power amp but is dangerous to speakers whose power ratings are not well above the amplifiers power rating. Move Parallel Inputs switches to the Stereo position.

Typical Stereo Setup
The preferred method of connecting input signals is with balanced XLRs (two conductors plus a shield wire, such as Carvins XLR8). Balanced input signals provide the highest gain and best noise rejection. 1/4 phone jacks are also capable of providing balanced input by using a stereo plug (ring-, tip+ & sleeve gnd). However, not all sources provide balanced outputs. In these cases an unbalanced 1/4 input is recommended (single conductor plus a shield wire, such as Carvins SH2 or SH15).

BLOCK DIAGRAM

MONO Y INPUT MODE
This feature allows both channels of the amplifier to be driven from a single input. To use this feature, plug one speaker cabinet into any of the channel 1 speaker output connectors and a second cabinet into any of the channel 2 speaker output connectors. Next, set the Accessory Group switches labeled PARALLEL INPUTS to their right-most position (as viewed from the rear of the amplifier). Now, signal entering any input will be available on both channels. The channel 1 level control will affect speakers connected to channel 1s output and channel 2 level will control speakers on channel 2s outputs. This feature is also used to daisy chain from one piece of equipment to the next (since channel 1 and channel 2 inputs are placed in parallel, any signal present on one will be available at the other).

OUTPUT CONNECTIONS
There are two 1/4 phone jacks available for speaker connections (one for each channel). Additionally, there are two pairs of binding posts that not only allow for high current connections to speakers but are also used when bridging the outputs (see section titled Bridging the Amp). Carvin supplies another alternative for connecting speakers to an F1200. Widely acclaimed audio connector manufacturer Neutrik, created a standard for speaker connections that provides high current capacity and ease of use. These connectors, dubbed Speakons, have been embraced by professionals as an improvement over previous standards.

RMS POWERMAX

RED binding post. (See the Typical Bridge Mono Triamp illustration, two pages back.) Speaker impedance in this mode is twice the actual load on each channel. For example; when operating an F600, whose minimum speaker impedance rating is 4, in BRIDGE MONO mode, speaker impedance must be no lower than 8. A 4 speaker load, in this situation, would violate the minimum impedance rating of the amplifier.
The PROTECT LED provides the operator with information about the status of the amplifier. There are 4 different reasons for it to light.

PROTECT LED

MATCHING MODE
When loading the speaker outputs to 2, set the RMS POWERMAX switch to the 2 position. When loading the speaker outputs to 4 or higher, set the RMS POWERMAX switch to the 4/8 position. Whether running 2 or 4 output power will remain at 600W per channel.
1. During power-up, the amplifier stays in a muted state until it determines all is well. First the fan(s) kick into high speed for a few seconds. After that it looks for DC Voltages on the outputs (F1200 only). Then if there are no short circuits on the outputs and its not overheated, the amp auto-initializes by disengaging the mute and turning off the PROTECT LED. This all happens during the first 5 seconds after power is applied. 2. If the output load draws excessive current, such as when a speaker cable short circuits, the amp detects this danger and mutes the channel. It then remains muted until power is turned off. Correct the problem then re-apply power to the unit. When power is reapplied the unit will come on normally. When the amplifier encounters this situation, it deals with it by muting only the affected channel. This way a shorted speaker cable on one side wont stop the show! 3. If the amp is subjected to sufficiently severe environmental or abusive load conditions to cause overheating, the unit will mute the affected channel. In this case, turning the power off and then on again will not reset the mute. The unit will have to cool off first. Fortunately the unaffected channel will remain on while the fan(s) cool the muted channel. Remedy the problem at once! Get the amp into a cooler environment or reconfigure the loads or whatever else can be done to prevent abuse. (When this situation occurs on F1200s, set the RMS POWERMAX switch to the 2 position. The amp will run cooler.) This condition mutes each channel independently so that a problem on one channel does not shut down the entire amplifier. Again, the show goes on. 4. (F1200 only.) When the amp detects high levels of subsonic content in the program material or DC on the output, it triggers the mute circuit. Since this circuit is nonlatching, the mute disengages as soon as the problem is corrected. As with the other protection modes, this one works on each channel independently. In summary: If the amplifier goes in and out of PROTECT every few seconds, then the problem is most likely excessive low frequencies (F1200 only). If the amplifier goes in and out of PROTECT every few minutes, then its probably overheating. If the amplifier goes into PROTECT and stays until you turn power off and back on again, it is experiencing over-current. (i.e., shorted speaker cable or too many speakers are connected.) If you turn the power off and back on a gain and the unit stays in PROTECT, then it is probably overheated and needs to cool off. Leave the power on so the fan(s) will cool it faster. It will come back on automatically when it is cool enough. Be sure to correct whatever caused it to overheat in the first place.

BIAMPING AND TRIAMPING

Y INPUTS
Switches 1 and 2 are used together to couple the input connectors. When the switches are in their right-most position the signal + of channel 1s input is tied to signal + of channel 2s. The same is true for signal -. This is useful when running in mono because only one input cable is required to drive both channels. It also provides a way of daisy chaining amps together. When using two or more amps, plug the source into any input of the first amp then from the other input run a jumper to any input on the second amp (and so on for additional amps).

STEREO BIAMP SYSTEM

The following illustration demonstrates the use of a Carvin XC3000 active crossover, an F1200 amplifier for lows and an F600 for highs. By moving the speakers Biamp switch (if so equipped) to the Biamp position, the user is able to feed power directly into the horn through the His input and into the woofer/mid through the Lows input. The crossover frequency of this setup was chosen to be 3.5kHz.

SUB FILTERS

Switches 3 and 4 control the low frequency cut-off point. Switch 3 is for channel 1 and 4 is for channel 2. These switches may be set separately to allow different cut-off frequencies for each channel. When in the left-most position, the SUB FILTER is engaged and the low frequencies are down 3dB at 15Hz. In the right-most position the filter is disabled. It is normal to run with the filters engaged. There is virtually no desirable audio content below 20Hz. Any energy below 20Hz will waste the amplifiers power and has a greater potential for damaging speakers.

GROUND LIFT SWITCHES

Many times sound systems are connected in such a manner to cause ground loops that result in audible hum. The purpose of switches 5 and 6 are to eliminate this ground loop. If your system emits audible hum try moving the GROUND LIFT switches to the other position. Each channel can be controlled independently but usually both channels will be lifted or grounded simultaneously GROUND LIFT switches such as the ones found in Carvin products are great for curing ground loop problems. A more complicated and expensive way would be to isolate two pieces of equipment from each other with audio isolation or line matching transformers. However, never defeat the AC cord safety ground in any piece of electrical equipment to open a ground loop. Doing so can damage equipment and cause serious electrical shock or electrocution.

MONO TRIAMP SYSTEM

This illustration shows a Carvin XC3000 active crossover, F1200 amplifier for lows, F600 for mids and F300 for the highs in BRIDGE MONO mode. Cabling from the speakers and their selector switches are set as in stereo mode above. However, the power amplifiers are setup in BRIDGE MONO mode and the speakers connect to the bridge outputs (channel 1s RED binding post is signal + and channel 2s RED binding post is signal -.) Warning: These power amplifiers produce extreme volume levels capable of causing permanent hearing damage.
