IMPORTANT SAFETY INSTRUCTIONS Read these instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus Keep these instructions. (including amplifiers) that produce heat. Heed all warnings. Do not defeat the safety purpose of the polarized or grounding-type plug. -

FRONT PANEL Channel Peak Indicators: These red LED indicators will light when their respective channel amplifiers have reached maximum output. To avoid clipping distortion, and to protect speakers from being damaged, reduce the input level until the Peak Indicator no longer lights. Channel Level Control Mounting Holes: These holes are provided for optional front panel mounting of the channel level controls (see Internal Modifications: Front Panel Level Controls on page 9). -
Page 9: Rear Panel
Channel Level Controls for the desired output volume from the CPA130. In mono-bridge mode, Channel 1 becomes the active input and Channel 2 input is inactive. As an option, the Channel Level Controls may be mounted to the CPA130 front panel (see Internal Modifications: Front Panel Level Controls on page 9). -
Page 10: Precautions
The CPA130 is designed to be installed in a standard 19" equipment rack. The amplifiers have cooling vents on both the top and bottom panels. Do not block the cooling vents in any way. When mounting the CPA130 in a rack, leave at least one rack-space above and below the amplifier to allow proper air flow. -
Page 11: Internal Modifications
This eliminates excessive current at low frequencies due to speaker transformer inductance, which can cause distortion or damage to the amplifier. If the CPA130 is used in mono-bridge mode to drive a distributed speaker system, it is only necessary for the Channel 1 High-Pass Filter to be enabled. -
