2 CHANNEL 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. Use the left (+) and right (–) terminals for bridged mode. Minimum speaker
cable size is 16 gauge (PG # SS162 or QS162). Use 12 gauge for bridged operation (SS122 or QS122). Minimum
impedance is 4 ohm bridged or 2 ohm stereo.
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)
Connect the optional RMD Voltage Display to this jack.
9. CROSSOVER CONFIG SWITCH
This switch controls the type of signal that reaches the speaker outputs. For a 100Hz highpass signal set
the switch to “100Hz HP”. For continuously variable lowpass signal set the switch to “VAR LP”. For a full
range signal set the switch to “BY”.
10. LP FREQ CONTROL
Adjusts the low pass crossover point for the speaker outputs. The crossover frequency is adjustable from
40 to 400Hz with a 12dB per octave low pass slope.
11. RCA INPUT
Connect preamp signal cables from the head unit to these terminals. To maximize noise rejection, we
recommend using Genuine Phoenix Gold RCA interconnects.
12. AUX OUT
Provides a full range signal for an additional amplifi er.
13. SENS CONTROL
This control is used to reach maximum amplifi er power with a wide variety of headunits. The amplifi er is
more sensitive to input signal when set to 0.1 and less sensitive when set to 8; turning the control
clockwise will increase speaker output volume.
14. SPEAKER LEVEL INPUT
Connect headunits speaker level outputs to these terminals using the supplied connector. The speaker
level input accepts a wide voltage range (200mV to 20Vdc) used with most headunit and OEM systems.

INSTALLATION
Note: Verify that your vehicle does not have a positive ground electrical system, this is very rare. A positive ground system is
the reverse of most standard vehicles in that the + battery terminal is connected to the vehicle chassis and is typically found in
some older European vehicles. If you have any questions do not proceed until you have verifi ed this. If it is a positive ground
electrical system please contact your dealer for assistance.
Caution: Please follow all the installation recommendations and instructions in this manual. Installation in any
manner not outlined in the manual will void your warranty and may possibly cause damage to the vehicle
and/or the amplifi er.
Warning: The battery ground should remain DISCONNECTED at all stages of installation.
LOCATION/MOUNTING
When selecting a location to mount your amplifi er, please keep in mind that electronics are sensitive to vibration, moisture, and
heat. Make sure the amplifi er is mounted in an area with ample ventilation and is not exposed to moisture or external heat.
For proper cooling, it is recommended to mount the amplifi er horizontal or vertical but not upside-down. Automobiles have a
certain level of normal vibration and we have designed the product with this in mind, but excessive vibration may cause dam-
age over time. Using the amplifi er for a template, mark the mounting holes in your selected area while following the preceding
guidelines. Verify that you are not going to damage sensitive vehicle systems by drilling where you have selected (look for the
gas tank, wires, etc…).
Remove the amplifi er and pre-drill the locations for the screws/bolts that you have selected that fi t the amplifi er and your new
installation purposes. Permanently mount the amplifi er to the selected location.
(Figure 3. shows a typical system confi guration).
Note: It is best to mount the amplifi er to some form of insulating surface, such as MDF, so that the chassis of the amplifi er
does not come in contact with the vehicle chassis (if a single screw makes contact with both the amplifi er and vehicle chassis,
it is not insulated). This will reduce the possibility of any ground related noises and will shield minor amounts of
radiated noises.

Installation Tip!
Real Power creates Heat!
Ryval amplifi ers are designed to give you every bit of electrical energy possible as output power. Be sure to install the amplifi er
in an area that has good airfl ow to prevent un-intentional thermal shut down.
Installation Tip!
System Tuning
Warning! Practice “Safe Sound” and Use Hearing Protection When Listening To Extreme Sound Pressure Levels
.
1
. Set the CONFIG switch according to your system setup.
2
. Set the amplifi er SENS Control to minimum (full counterclockwise).
3
. If using the amplifi er in Lowpass mode, set the LP FREQ control to the 10 O’clock position. This is a
starting point for the crossover; you may need to fi ne tune this setting later.
4
. Turn the headunit on with the volume set to minimum.
5
. Set the headunit’s tone controls, balance and fader to the center (fl at) position and turn off any
loudness features or other processing effects.
6
.
Play a CD that represents what type of music you usually listen to. Set the volume control of the head
unit up to 90% of total volume or until you hear distortion if you are using the headunit’s internal amplifi er.
7
. I
ncrease (turn clockwise) the SENS Control for the amplifi er until you hear distortion then slightly
decrease the sensitivity control until the distortion is not audible. The volume level should still be very loud,
but free from nearly all distortion
.
8
. With all speakers in the car playing, listen to the CD at this same high volume and make sure all
channels blend properly. For example, if the front speakers overpower the subwoofer, then slowly
balance the system so all channels reach maximum output without distortion at this volume level.
9
. The volume level set in step 6 will be your maximum volume level for your system. If you exceed this
level, the onset of distortion will become very noticeable.

2 CHANNEL POWER AMP OWNERS MANUAL
TROUBLE-SHOOTING
SYMPTOM: POSSIBLE CAUSE
No power:
Check voltage at amplifi er with a DMM (volt meter), B+ and REM (with source unit on) the voltage should register
between 12.2V-14.6V when using the attached ground lead of the amplifi er. Check fuse at amplifi er and at the battery. Use a
meter to verify connection from one end of the fuse to the other, breaks may not always be visible. If fuse is blown, check the
power wire and also the amplifi er for a short. If the short is in the power wire, repair it. If the short is in the amplifi er itself, see your
Phoenix Gold dealer. If no short is present replace the fuse.
Power without sound:
Turn the amplifi er off and check all input and output signal cables and power connections. Check the
speakers for shorts with a DMM (volt meter) or by connecting them to another audio source. After making sure everything is
correct, turn the amplifi er on again.
Power without sound and status LED is lit red:
The continuous red light of the power indicator signals a high internal operating
temperature, which results in the amplifi er switching off temporarily. When the amplifi er cools down to a safe level, the amp will
automatically restart. The continuous red light of the power indicator can also indicate a shorted speaker lead or battery voltage
that is either too high or too low for proper operation.
No sound from one side:
Check balance control. Check speaker connections. Check signal input connection.
Very low output:
Check your source unit’s fader control, or the amplifi er’s Input Sensitivity Level.
Frequent automatic amplifi er shut down:
A indicates that the amplifi er is operating at a continually undesirable high internal
temperature. High operating temperature can be caused by inadequate ventilation: Refer to the sub-section titled LOCATION for
better amplifi er location. High operating temperature can also be caused by an excessively low impedance load. For instance be-
low 2 ohms stereo or 4 ohms bridged. Check for bad speakers or bad passive crossover components. If all else fails, try rewiring
the entire system. High operating temperature can be caused by an incorrect input sensitivity level, refer to sub-section titled
INPUT SENSITIVITY ADJUSTMENT.
“Motor Boating” - the power indicator going off repeatedly when the audio system is on:
Check the amplifi er’s connection
to the battery. Check battery voltage. If low, recharge or replace battery. Check all ground connections.
Whining noise when engine is running:
Reroute power cable from battery to source unit directly (include fuse), bypassing the
battery terminal in the fuse box. Check power connections to be sure they are clean. Check the battery ground making sure the
battery terminals and chassis ground are clean. Run a ground wire from the source unit to the ground point of the amplifi er and
remove old source ground.
CAUTION:
Do not disconnect the Power Amplifi er’s ground when the system is on. This could damage the amplifi er.
