• Loudspeaker Protection - When power is first applied, the speaker protection relay is

open, preventing transients from reaching the loudspeakers. After the internal power

supplies have stabilized, the relay will close, connecting the amplifier output to the load.

The yellow Protect LEDs will illuminate during this power-up process.

• Thermal Protection - The amplifier protection circuitry monitors itself for excessive

internal operating temperatures. In the event this circuitry detects abnormal thermal

conditions (blocked cooling fan or high ambient temperatures), the speaker relay

will disconnect the speaker load from the amplifier. Once the internal operating

temperature drops back to a safe level, the relay will close, reconnecting the speaker load

to the amplifier.

• Short Circuit Protection - The yellow Protect LEDs will illuminate should the amplifier

detect a short circuit on the attached speaker load or if the load impedance is too low.

When this condition is detected, the internal speaker relays will open up, disconnecting

the load from the amplifier. The protection circuitry will stay activated until the fault is

cleared.

Note: Once the specific fault has been corrected, the power may have to be cycled to reset the

protection circuitry.

3. Signal “Status” LED Indicator

The green “Status” LEDs will illuminate once the input signal has reached -26 dBV or higher.

9. Stereo/Parallel/Bridge Switch

This 3 position switch changes the operating mode of the amplifier. DO NOT move this switch when the amplifier is powered up and connected to a load.

• Stereo - When the switch is set to this position, the amplifier operates as two independent

amplifiers. Use this position for stereo program material or for two discreet paging/sound

masking zones.

• Parallel - When the switch is set to this position a single mono input signal is to be used.

Connect the input wiring to either channel 1 Or channel 2. The one input signal will drive both amp channels. Use this position when two speaker zones are being fed by a mono signal. (See note below)

• Bridge - When the switch is set to this position, connect the mono input signal to channel

1 ONLy. The speaker load is connected across the two positive terminals as shown in

Figure 7 on page 10. The amplifier will deliver approximately twice the voltage across the

load. Please observe the minimum load specification when operating in Bridge mode.

Note: A 6 dB loss of output power will occur when operating in parallel mode. To over come this loss, connect the positive terminal on input 1 to the positive terminal on input 2 and connect the negative terminal on input 1 to the negative terminal on input 2. Short lengths of

22-gauge wire can be used.

10. CH1/CH2, Low Impedance Speaker Outputs

The amplifier direct speaker outputs bypass the internal constant voltage transformers and are used for direct connection to loudspeakers. The amplifier will operate into 2, 4, and 8 Ω loads

The use of appropriately sized spade lugs is recommended for speaker wire termination; connect the speaker line common to the “-” terminal and the positive lead to the “+” terminal.

For high power applications, use the proper gauge wire for the speaker connections. Contact

Atlas Sound Tech Support (1-800-876-3333) for assistance in determining the proper size wire.

11. CH1/CH2, 25/70.7/100V Speaker Outputs

The amplifier will drive constant voltage speaker loads for use in commercial business music/ paging systems and sound masking systems. The use of spade lugs for terminating and connecting the speaker home runs is recommended. The speaker line common connects to the

“0” terminal and the positive lead connects to the desired voltage for required system requires for proper operation (Figures 8,9,10; Pages 11-12).

Calculating Constant Voltage Loads

To calculate the maximum quantity of transformer coupled loudspeakers you can safely connect to the amplifier, first add up the total number of speakers that will be connected to one channel of the amplifier, then multiply that total speaker number by the tap setting you plan to use. The result will be the load in watts that the amp output channel will see. It is good engineering practice to leave a 20% margin below the maximum rated output power of the amplifier. In this case, one channel of the amplifier can supply 350 W of power at

70.7V. Derate this by 20%, leaving 280 W of power available for constant voltage speakers.

Balanced Inputs

Balanced input wiring requires two conductors with shield (22-gauge is the most common). The use of crimp type spade lugs is highly recommended for permanent installations. At the input section located on the rear of the amplifier, wire the “hot”/positive lead to the “+” terminal, the

“common”/negative lead to the “-” terminal and the shield/drain to the “ground” terminal (Figure 3).

The XLR inputs (+4 dB balanced line level) can be utilized with standard 3-pin XLR male to female patch cables to accommodate outputs from a mixer, equalizer, or crossover when the amplifier is used as a portable sound system amplifier.

Owner’s Manual unbalanced Input

Unbalanced wiring typically is found on consumer equipment (CD players, DVD players, etc.) and is generally a compromise of noise rejection and cable lengths. A single conductor and an overall shield are most common, as in the standard cables supplied with consumer equipment. Keep unbalanced wire lengths within 10' between equipment, wire the hot lead to the “+” terminal, and the shield to the ground terminal. Install a jumper wire between the “-” terminal and the ground – a loss of gain will result without this jumper (Figure 4).

Bridge mono Transformer Coupled Output Wiring for 140V/200V Output Operation

The amplifier can be configured to drive 140V and 200V speaker lines.

Please observe all necessary safety precautions as the potential for electric shock at the speaker terminals is present.

With the amplifier turned OFF, move the rear mounted selector switch to the “Bridge” position and connect the input signal to channel 1. Connect your speaker load across the “+” terminals of both output terminals as follows:

• 140V Operation - Connect the positive lead of the speaker load to the channel 1 70V

positive “+” terminal, the negative speaker lead connects to the channel 2 70V positive

“+” terminal. Connect a suitable jumper wire between the two terminals labeled “0”.

Consult your local codes to determine if Class I wiring is required (Figure 11).

• 200V Operation - Connect the positive lead of the speaker load to the channel 1 100V

positive “+” terminal, the negative speaker lead connects to the channel 2 100V positive

“+” terminal. Connect a suitable jumper wire between the two terminals labeled “0”.

Consult your local codes to determine if Class I wiring is required (Figure 12).

CAuTION: A high voltage potential exists across the two “+” speaker terminals when operating in any Bridge mode application!
