HIGH PASS
This position is used to activate the HIGH PASS filter for the corresponding channel. This filter will limit the frequencies sent to the associated
amplifier channel to 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.
FULL RANGE
As the name implies, the Full Range position on this switch allows all frequencies to pass to the amplifier. Normally used when connecting a
full range speaker enclosure to the amplifier's output.
SUBWOOFER
This position is used to activate the LOW PASS filter for the corresponding channel. This filter will limit the frequencies sent to the associated
amplifier channel to frequencies below 100 Hz. In situations where separate subwoofer cabinets are being used, this position would indicate
connecting the subwoofer speaker cabinet to the channel associated with the Subwoofer switch.
This 1/4” jack supplies parallel output signals from the associated channel for patching to this amplifier and/or additional power amplifier
inputs.
Input connections are made via the 3-pin XLR (pin 2+) or 6.3 mm plug combination connectors on the rear panel of the amplifier. The inputs
are actively balanced.
All models have one combination 4 pole twist lock output connector per channel. Channel A ouput allows for CH A 1+ Pos / 1- Neg and
channel B 2+ Pos / 2- Neg to use a single 4 conductor speaker cable.
