FRONT & REAR CONNECTIONS

FRONT PANEL

1. POWER SWITCH To turn the unit ON or OFF, press the upper or lower portion of this button. Before turning on the amplifier, check all connections and turn down the level controls. A momentary muting is normal when turning the amplifier on or off. (Caution: Always turn on your power amplifier last, after all your other connected equipment, and always turn off your power amplifier before your other connected equipment.) 2. POWER LED INDICATORS These LEDs illuminate when the power is turned ON. 3. CLIP (PEAK) LED INDICATORS These LEDs illuminate if any section of the power amplifiers output are within 3DB of clipping. Occasional blinking of the LEDs are acceptable, but if they remain on more than intermittently you should turn down either the power amplifiers level controls or
reduce the output level of the preceding component to avoid audible distortion. 4. SIGNAL LED INDICATORS These LEDs illuminate to confirm the presence of an input signal greater than 100 mV at that channel of the amplifier 5. PROTECT LED INDICATORS These LEDs illuminate if the power amplifiers output connection is shorted or the load impedance is too low. When either of these LEDs is lit up, turn OFF the power and check the outputs connection to verify that it is correct, then turn ON the power again. 6. LEVEL CONTROLS These control the level of signal coming into each channel. The actual voltage gain of the amplifier is shown in dB. Turn these controls counterclockwise if the peak LEDs illuminate steadily (indicating too strong an input signal).

BACK PANEL

7. POWER CONNECTOR The cord connector is used to connect the AC power source to your power amplifier. (CAUTION: DO NOT REMOVE THE CENTER GROUNDING PIN.) 8. FUSES Fuse holders for 20A/250V 3AG fuses. If these fuses continuously blow, shut off the unit and have it serviced by qualified service personnel. 5
9. GROUND LIFT SWITCH Switch to right to disconnect the chassis from ground if necessary to eliminate hum caused by ground loops. 10. AC VOLTAGE SELECTOR SWITCH Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V (60Hz) or ~230V (50Hz). A cover plate is provided to ensure that this switch is not accidently reset or tampered with between uses.

11. L/R CHANNEL OUTPUT CONNECTORS Connections are as depicted on the rear panel and in the following CONNECTIONS section on page 7 of this manual. 12. BALANCED INPUT CONNECTORS (1/4" TRS & XLR) These 1/4" (6.3mm) TRS (Tip/Ring/Sleeve) phone jacks and XLR jacks are compatible with balanced inputs and are wired as Tip/ Pin 3 = (+), Ring/Pin 2 = (-), and Sleeve/Pin 1 = Ground. Normal maximum input level at clipping is 1.15V RMS (+ 4dB). Input impedance is 10K Ohms. Since the TRS phone jacks and XLR jacks are wired internally in parallel, you can parallel this unit with another amplifier by using either the LINE 1/4" jack or the XLR jack (depending on which youre using to input your signal) to output the signal to the input jack of the other amplifier. The 1/4" TRS phone jacks can also be used for unbalanced inputs. For TRS phone plugs, simply connect the unused side of the balanced input to ground. For 1/4" TS phone plugs, no change is necessary for compatibility with this input. Balanced input signals are recommended as they are less prone to AC hum. For long cable runs a source of less than 600 ohms output impedance is needed to avoid signal loss. For short cable runs an unbalanced signal input should be suitable. For stereo (two-channel) operation, use the inputs for both CH-A and CH-B; for parallel or bridged mono operation, use only CH-A input. (See MODE SELECTOR SWITCHES below for more explanation.) 13. MODE SELECTOR SWITCH The XA Series amplifiers offer 3 modes of operation: PARALLEL, STEREO & BRIDGED. Slide the switch to one of the three positions for you application. PARALLEL (MONO) INPUT - This mode allows both channels to operate in parallel with the same signal and without requiring a Y-cord. In this mode the inputs for both channels are internally connected, so that you only need to feed a signal into one of the channels. This still allows independent control of each channel. (Note: Do not select this Parallel mode when feeding the amplifier 2 separate signals.) (Note: Do not use both unbalanced and balanced cables in the same set-up as that can unbalance all the connections when daisy-chaining, resulting in hum.) STEREO INPUT - This is the most common mode generally used, and allows independent control of 2 separate signals such as stereo playback, main and monitor live mixes, and biamp operation (highs in one channel and lows in the other). BRIDGED MONO - This mode combines the power of both channels to drive a single speaker. In this mode the amp produces 4 times the peak power and 3 times the sustained power into a 4 or 8 ohm speaker than each channel can deliver separately in stereo or parallel mode. (CAUTION: In this mode the amplifier can deliver high power into a speaker. Make sure that the speaker, connectors and wiring can handle this output. Note that for prolonged overdriven outputs into a 4 ohm speaker the breaker may trip, so care must be taken not to overload the amplifier in such operation.) Connect the input signal to CH-A input for bridged mono operation. 14. FANS The two dual-speed fans switch between idle speed and high speed automatically to maintain the proper internal operating temperature.

INSTALLATION

To ensure years of enjoyment from your NADY AUDIO XA Series amplifiers, please read and understand this manual thoroughly before using the unit.

INSPECTION

Your XA Series amplifiers was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit. (Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.)

RACK MOUNTING

The XA Series amplifiers are designed for standard 19" rack mounting as well as stack mounting without a cabinet. Use 4 screws and washers for mounting to the front rack rails. It is also a good idea to support the amps also in the rear, especially for mobile use where the amps will be subjected to shocks.

AMPLIFIER COOLING

Also pay close attention to the cooling requirements. Never block the air vents in the back side and front of the amplifier if the load seen by amplifier is less than 4 ohms and the amplifier is being run at high output levels. For best results, in such high output power applications you should augment the amplifiers air flow with a rack cooling system.

CONNECTIONS

The following instructions describe the most common ways to install your amplifier into a sound system. 1. Turn off the amplifier power switch before making any connections. 2. The XA Series amplifiers maybe operated in one of three modes (stereo, bridged-mono, and parallel mono). Refer to the following wiring diagrams for the speaker connections you wish to make. (Note: Nady Systems assumes no liability for damaged speakers resulting from improper wiring, careless amplifier use, or over powering.)

Stereo (Two-Channel) Mode
To put the amplifier into stereo mode, first turn the amplifier off, then slide the MODE SELECTOR SWITCH (13) to the bottom STEREO position, and properly connect the input/output wiring as shown. (Note: Do not connect a speaker load less than 2 ohms as it can damage your amplifier.)

CHANNEL B

CHANNEL A

Parallel (Mono) Mode

To put the amplifier in parallel-mono mode, first turn the amplifier off, then slide the MODE SELECTOR SWITCH (13) to the middle PARALLEL (MONO) position and properly connect the input wiring as shown. A signal into any input jack will drive both channels directly. You can patch the input signal on to any other amps using any of the remaining input jacks. (Note: Do not connect a speaker load less than 2 ohms as it can damage your amplifier.) [Note: Do not use the PARALLEL (MONO) switch when feeding the amp 2 separate signals.]

Bridged Mono Mode

To put the amplifier in bridged mono mode, turn the amplifier off and slide the MODE SELECTOR SWITCH (13) toward the top BRIDGED position and properly connect the input/output wiring as shown. The signal is input into CH-A. Keep the level control of channel B turned completely down (counter clock wise). (Note: Do not connect a speaker load of less than 4 ohms as it can damage your amplifier.) (Note: This mode produces a large amount of power. Be sure that your wiring and speaker can handle it.)

When selecting an amplifier from among competing brands with similar features, be sure that you are comparing the correct output power ratings. First, make sure all the output power ratings you are comparing are stated in Watts RMS, which most correctly reflects the average power the amp can sustain with continuous use. Manyamps show a rating in Watts only. Generally, these refer to peak Watts capability, which can be up to twice the RMS rating. Also, these measurements are sometimes taken at 10% distortion (THD). Thisproduces a higher reading than the correct measurements taken at 1% THD, which more accurately reflects the desired audio in any application. It is also important to make sure you are comparing power ratings at the same speaker load. Youwill notice that the lower the load (e.g.,2 ohms vs. 4 ohms, or 8 ohms), the higher the reading. Always compare apples to apples when choosing the amp power youwant. Note that Nady Audio amps are all rated at Watts RMS at1% THD.
