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 specic, 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 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 congured 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.
