1. Power Switch

This rocker switch supplies power to the CP700 amplifi er. 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
amplifi er. The output relays will disconnect the speaker loads when the protection circuitry detects a
fault condition.

• Loudspeaker Protection - When power is fi 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 amplifi er 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 amplifi er. Once the internal operating temperature drops back to a safe
level, the relay will close, reconnecting the speaker load to the amplifi er.

• Short Circuit Protection - The yellow Protect LEDs will illuminate should the amplifi 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 amplifi er. The protection circuitry will stay activated until the fault is cleared.

Note: Once the specifi 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 -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 specifi 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.

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 confi gured 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.

8. CH1/CH2 Loop Through

Two male XLR (one per channel) are provided for looping the input signals to other CP700s or similar
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 CP700. DO NOT move this switch when the
amplifi er is powered up and connected to a load!

• Stereo - When the switch is in this position, the CP700 operates as two independent amplifi ers.
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 specifi cation 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.

OWNER'S MANUAL

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, fi rst 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 amplifi er (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).
