A. Variable Crossover 1-2 - Built in 12db filter with crossover frequencies
between 30Hz – 290Hz.
B. Crossover Selection Switch 1-2 - The HIGH pass attenuates low
frequencies and is used with mid-range speakers and tweeters. LOW
Pass attenuates high frequencies and is used for subwoofers. Full does
not attenuate any frequencies and is for full range speaker systems.
C. Gain Control 1-2 -
This is the input sensitivity gain control for channels 1&2.
D. Mono Stereo Selection Switch - Stereo is used in applications where
stereo is needed and bridge outputs are not used. Mono is used when
bridging mono for a subwoofer for example. Both the left and right
channels are combined into a mono signal that is sent to both outputs
giving you a true mono output.
E. Led color selection switch for Wet Sounds Badge logo
F. Bass Boost Control 1-2 – This is a variable boost level for the low
frequencies to which the amplifier is set at on in “G”. Bass Boost
should only be used in small amounts when running subwoofers ONLY.
Do not use Bass Boost when running full range speakers.
G. Bass Boost Frequency - Adjustment from 30Hz to 130 hz.
H. Input source selection - When on ch 1-2 the channel 3-4 outputs
are active from channels 1-2 input. Eliminating the need for external y
adapters. This is useful if you are using one amp to power all speakers
in the same zone and do not need any type of fading ability or need
separate control from an EQ. When on ch 3-4, you will need a RCA
cable direct into the 3-4 RCA input to activate the 3-4 outputs.
I. Variable Crossover 3-4 - Built in 12db filter with crossover frequencies
between 30Hz – 290Hz
J. Crossover Selection Switch 3-4 - The HIGH pass attenuates low
frequencies and is used with mid-range speakers and tweeters. LOW
Pass attenuates high frequencies and is used for subwoofers. Full does
not attenuate any frequencies and is for full range speaker systems.
