Ryval ®Amplifi ers
CLASS D MONO-BLOCK
POWER AMP OWNERS MANUAL
1. STATUS LED
Green- Amplifi er is powered “ON”
2. PROTECT LED
Red- If the internal heatsink reaches 80 degrees Celsius the amplifi er shuts down until the internal
temperature falls below 75 degrees. It also lights if a direct short is present on the speaker outputs.
If this occurs, check for shorted speakers and cycle power to resume operation.
3. REMOTE TURN-ON TERMINAL
Connect to a switched 12 Vdc source such as the headunit’s “remote” or power antenna wire.
4. B- TERMINAL (CHASSIS GROUND)
Connect to a clean, solid chassis ground. Remove all paint and dirt from the chassis connection point.
Minimum cable size is 8 gauge. Keep the cable as short as possible.
5. B+ TERMINAL (BATTERY POSITIVE)
Connect directly to the positive battery terminal. Minimum cable size is 8 gauge. Remember to properly
fuse this cable within 18 inches of the positive battery terminal.
6. SPEAKER OUTPUTS
Used to connect the amplifi er to speakers. The separate + and – terminals are internally wired in parallel.
Minimum speaker cable size is 12 gauge (PG # SS122 or QS122). Lowest recommended
impedance is 2 ohms.
7. FUSES
Used to protect the amplifi er. If replacement is necessary, use the same size and type indicated on the
endpannel.
Never use a fuse with a higher amp rating.
8. REMOTE VOLTAGE DISPLAY INPUT (RMD)

9. LPL PORT
This port is for connecting the optional LPL44 Remote Lowpass Level Control knob allowing up to 20dB
of volume adjustment.

Adjusts the lowpass crossover point for the speaker outputs. The crossover frequency is adjustable from
40 to 300Hz with a 12dB per octave lowpass slope.
11. BASS BOOST CONTROL

Connect preamp signal cables from the head unit to these terminals. To maximize noise rejection, we
recommend using Genuine Phoenix Gold RCA interconnects.
