Marine Amplifier: The Wet Sounds Hydro-Tech series amplifiers,
with conformal coated PCBs, are specifically designed for marine applications.
However, the amps are not waterproof, and should not be mounted where they are
likely to get wet.
4-Channel Amp: The HT-4 is a 4-channel amplifier, basically
two 2-channel amps in one chassis. The inputs, outputs, and controls are labeled
CH1/CH2 or CH3/CH4.
Mounting Feet: Using the included mounting feet adds
approximately 1/2" to the height of the amp, but allows you to hide
the wiring under the chassis.
Logo: The Wet Sounds logo mounts over the status LED, on the
top of the amp. It can be mounted vertically or horizontally.
End Covers: There are removable covers on both ends of the
amp to help protect the controls and connections. The covers can be painted.
Note: A 3mm Allen wrench (not included)
is needed to remove the covers. They must be removed during
Control Panel Cover: All the controls are protected by a rubber
cover to help keep them dry.
Input: When only using one pair of the RCA inputs, set the
Input switch to 2CH. When using all four RCA inputs, set the Input switch to
Gain: CH1/CH2 and CH3/CH4 have independent gain controls,
continuously variable rotary controls; 200 mV to 5 V.
Crossover: CH1/CH2 and CH3/CH4 have independent crossover
controls. Each 12 dB/octave crossover can be set to low pass, high pass, or full
(crossover is bypassed and the amp output is full range). The crossover points
are adjustable from 50 Hz to 250 Hz.
Bass Boost: CH1/CH2 and CH3/CH4 have independent bass boost
controls; both centered at 45 Hz, they are continuously variable from 0 dB (flat)
to +12 dB.
Power Terminal Block: The amplifier has a power/ground terminal
block that detaches from the amplifier, making it easier to connect the power and
ground wires. Once the connections are made, the terminal block plugs into the
amplifier. The power/ground block has set screw terminals and will accept 4 gauge
Speaker Terminal Blocks: The speaker terminal blocks also
detach from the amplifier. One speaker block has set screw terminals for two
speakers and the remote turn-on lead, the other has set screw terminals for two
speakers. All the terminals will accept 12-16 gauge wire.
Preamp Inputs: The amplifier has two pair of RCA jack inputs.
Preamp Outputs: There is also one pair of pass-through preamp
outputs, making it easy to connect another amplifier without running an extra set
of RCA cables.
Note: The preamp inputs and preamp outputs
are extended 5" from the amp on pigtail wires.
Fuses: The amplifier is protected by two 25-amp ATO blade-type
