FRONT PANEL DESCRIPTION
Figure 1
1. Power Switch
This rocker switch supplies power to the amplier. A red LED located above the power
switch will illuminate when the amplier is switched on.
2. Protect LED Indicators
The amplier features several types of protection circuitry to prevent damage during
power-up or fault conditions. If any of these LEDs illuminate, one of the various protection
features is safeguarding the amplier. The output relays will disconnect the speaker loads when
the protection circuitry detects a fault condition.
•Loudspeaker Protection - When power is rst 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 amplier output to the load.
The yellow Protect LEDs will illuminate during this power-up process.
•Thermal Protection - The amplier 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 amplier. Once the internal operating
temperature drops back to a safe level, the relay will close, reconnecting the speaker load
to the amplier.
•Short Circuit Protection - The yellow Protect LEDs will illuminate should the amplier
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 amplier. The protection circuitry will stay activated until the fault is
cleared.
Note: Once the specic 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.

4. Limit LED Indicator
The CP400 and CP700 come equipped with limiter circuitry and LEDs to indicate when this
circuitry is activated. The limiter circuitry engages only when the input signals reach a specic,
factory set magnitude. Once this limit has been reached, the circuitry will reduce the input level
enough to prevent clipping at the speaker output terminals.
REAR PANEL DESCRIPTION
Figure 2
5. Gain Controls
One stepped attenuator per channel increases or decreases the sensitivity by 2 dB per step.
Maximum voltage gain is 32 dB.
6. CH1/CH2 Inputs (XLR Connectors)
Two female XLR inputs (one per channel) are provided. These inputs are balanced and
congured as follows: pin 1 ground, pin 2 +, pin 3 -. The XLR connections are typically used in
portable audio systems where quick connect and disconnect is warranted.
7. Balanced Barrier Strip Inputs
Balanced inputs are provided on this barrier strip for permanent installation applications. The
use of the appropriate spade type lug is highly recommended for best connection integrity and a
neat, professional appearance.
8. CH1/CH2 Loop Through
Two male XLR (one per channel) are provided for looping the input signals to other devices.
These connectors are wired in parallel with the female XLR inputs, pin for pin.

9. Stereo/Parallel/Bridge Switch
This 3 position switch changes the operating mode of the amplier. DO NOT move this switch
when the amplier is powered up and connected to a load.
• Stereo - When the switch is set to this position, the amplier operates as two independent
ampliers. 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 amplier will deliver approximately twice the voltage across the
load. Please observe the minimum load specication 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 amplier direct speaker outputs bypass the internal constant voltage transformers and are
used for direct connection to loudspeakers. The amplier 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 amplier 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 amplier, rst add up the total number of speakers that will be connected to
one channel of the amplier, 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 amplier. In this case, one channel of the amplier can supply 350 W of power at
70.7V. Derate this by 20%, leaving 280 W of power available for constant voltage speakers.

INPUT WIRING
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 amplier, 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 amplier is
used as a portable sound system amplier.

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).

SPEAKER OUTPUT WIRING
Low Impedance Direct Coupled Output (Stereo)
For direct coupled operation into 2, 4, and 8 Ω loads, connect the loudspeaker leads to the barrier
strip connections labeled “Direct Output”; connect the hot lead to the “+” terminal and the
common lead to the “-” terminal. The use of heavy gauge wiring is recommended to avoid voltage
drops, which can occur as a result of wasted power in the cable. Contact Atlas Sound Tech Support
(1-800-876-3333) for suggestions on cable capacities. Be sure you know the quantity of speakers
and cable lengths before calling (Figure 5).
Low Impedance Direct Coupled Output (Parallel Mono)
Observe the speaker connection information in the preceeding paragraph (Stereo Direct Coupled
Output). With the amplier turned OFF, move the rear mounted selector switch to the “Parallel”
position and connect your mono input wiring to either the channel one or channel two inputs. Both
channels will be driven from this mono signal (Figure 6).

Bridge Mono Configuration (Direct Coupled)
If higher power levels are required, the Atlas amplier can be used in Bridge Mono mode, which
utilizes both channels of the amp across the speaker load.
With the amplier turned OFF, move the rear mounted selector switch to the “Bridge” position and
connect the input signal to channel one. Connect your speaker load (4 and 8 Ω only) across the “+”
terminals of both channels, with channel 1 being positive and channel 2 being negative (Figure 7).
CAUTION: A high voltage potential exists across the two “+” speaker terminals when operating in
any Bridge Mode application!
Figure 7
25V, 70.7V, and 100V Transformer Output Wiring
For transformer coupled operation into high impedance loads, connect your loudspeaker leads
to the barrier strip connections labeled “Audio Transformer.” Connect the speaker home runs as
follows:
• 25V - Connect the positive speaker lead to the terminal labeled “100” and the negative
speaker lead to the terminal labeled “70” (Figure 8).
• 70.7V - Connect the positive speaker lead to the terminal labeled “70” and the negative
speaker lead to the terminal labeled “0” (Figure 9).
• 100V - Connect the positive speaker lead to the terminal labeled “100” and the negative
speaker lead to the terminal labeled “0” (Figure 10).
Note: Refer to page 6 of this manual to the paragraph entitled “Calculating Constant Voltage
Loads” to determine how many transformer coupled loudspeakers you can drive with the Atlas
amplier.

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 amplier 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!
