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 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 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 configured 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.
