FRONT PANEL DESCRIPTION
Figure 1
1. Power Switch
This rocker switch supplies power to the CP700 amplifier. A red LED located above the power switch
will illuminate when the CP700 is switched on.
2. Protect LED Indicators
The CP700 features several types of protection circuitry to prevent damage during turn-on or fault
conditions. If any of these LEDs illuminate, one of the various protection features is safeguarding the
amplifier. The output relays will disconnect the speaker loads when the protection circuitry detects a
fault condition.
•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 CP700 protection circuitry monitors itself for excessive internal
operating temperatures. In the event of this circuitry detecting abnormal thermal conditions
(blocked cooling fan and 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 -26dBv or higher.

4. Limit LED Indicator
The CP700 comes equipped with limiter circuitry and LEDs to indicate when this circuitry is activated.
The limiter circuitry engages only when the input signals reach a specific, 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.

5. Gain Controls
One stepped attenuator per channel increases or decreases the sensitivity of the CP700 2dB per step.
Maximum voltage gain of the CP700 is 32dB.
6. CH1/CH2 Inputs (XLR Connectors)
Two female XLR inputs (one per channel) are provided. These inputs are balanced and configured as
follows: pin 1 ground, pin 2 plus, pin 3 minus. 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.

9. Stereo/Parallel/Bridge Switch
This 3 position switch changes the operating mode of the CP700. DO NOT move this switch when the
amplifier is powered up and connected to a load!
• Stereo - When the switch is in this position, the CP700 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 in this position and a mono input signal is to be used, connect the
input wiring to either channel one OR channel two. 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 in this position, connect your mono input signal to channel one
ONLY. The speaker load is connected across the two positive terminals as shown in Figure 7 on
page 10. The CP700 will deliver approximately twice the voltage across the load. Please
observe the minimum load specification when operating in Bridge mode.
10. CH1/CH2, Low Impedance Speaker Outputs
The CP700 direct speaker outputs bypass the internal constant voltage transformers and are used
for direct connection to loudspeakers. The CP700 will operate into 2, 4, and 8 Ohm 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 CP700 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 whatever voltage your system requires for proper operation.
Calculating Constant Voltage Loads
To calculate the maximum quantity of transformer coupled loudspeakers you can safely connect to the
CP700, first add up the total number of speakers that will be connected to one channel of the CP700,
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 CP700. In this case, one channel of the CP700 can
supply 350W of power at 70.7V, so derate this by 20%, leaving 280W of power available for constant
voltage speakers.
Note: A 6dB 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 minus terminal on input 2. Short lengths of 22 gauge wire can be used.

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 CP700, wire the "hot"/positive lead to the "+" terminal, the "cold"/negative lead to the "-"
terminal and the shield/drain to the "ground" terminal.
The XLR inputs (+4dB 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 CP700 is used as a
portable sound system amplifier (Figure 3).

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 "bargain type" cables supplied with consumer gear. Keep unbalanced wire
lengths within 10 feet between equipment, and wire the hot lead to the "+" terminal, and the shield to the
ground terminal. Do not forget to install a jumper wire between the "-" terminal and the ground, as 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 Ohm 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, resulting in
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 CP700 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).
