•
ACTIVE—indicates that the channel is operational. The light
illuminates under normal operation and remains on, even when the
channel is in ACL gain reduction. If the light is off, there is no signal at
the output connectors.
C AC Power Switch Turns the power on and off. This is a combination magnetic circuit breaker
and switch.
D Rack Mounting Ears Provides mounting holes for rack installation.

Letter Component Description
A AC Power Inlet This is the receptacle for an IEC line cord, which provides AC power to the
unit. Connect the line cord to this connector to provide power to the unit.
Damage to the equipment may result if improper line voltage is used. (See
line voltage marking on unit). The 120VAC CDA7.5 gets a power cord
retaining clamp.
Never break off the ground pin on any equipment. It is provided for your
safety. If the outlet used does not have a ground pin, a suitable grounding
adapter should be used and the third wire should be grounded properly. To
prevent the risk of shock or fire hazard, always make sure that the
amplifier and all associated equipment is properly grounded.
B Outputs All models have one combination 4 pole twist lock output connector per
channel. Channel A output allows for CH A 1+ Pos / 1- Neg and Channel B
2+ Pos / 2- Neg to use a single 4 conductor speaker cable.
C Inputs with Channel Mode
Switch and Thru/Out
Jacks
Provides the connecting inputs and input controls. Input connections are
made using the 3-pin XLR (pin 2+) or 6.3 mm (1/4 in.) plug combination
connectors on the rear panel of the amplifier. The inputs are actively
balanced.
The following channel modes are available:
•
SUB (subwoofer)—activates the low pass filter for the corresponding
channel. This Linkwitz-Riley filter limits the frequencies sent to the
associated amplifier channel to those frequencies below 100 Hz. in
situations where separate subwoofer cabinets are being used, this
position indicates connecting the subwoofer speaker cabinet to the
channel associated with the subwoofer switch.
• FULL-RANGE—allows all frequencies to pass to the amplifier. This
setting is normally used when connecting a full range speaker
enclosure to the amplifier’s output.
• HIGH-OUT (switch high pass)—activates the high pass filter for the
corresponding channel. This Linkwitz-Riley filter limits the frequencies
sent to the associated amplifier channel to those frequencies above
100 Hz. In situations where separate subwoofer cabinets are being
used, this position would indicate connecting the mid-high frequency
speaker cabinet to the channel associated with the high pass switch.
