AUDIO PREAMP INPUT
The RS amplifiers feature RCA preamp inputs. Run RCA cables from your sound source to the inputs of the amplifier. We suggest the use of high quality shielded RCA patch cords to help reduce and eliminate unwanted electrical noise from your system.
Be sure to run the RCA cables on the opposite side of the vehicle that you used to carry the power and ground leads of the amplifier.
AUDIO PREAMP OUTPUT
The RS amplifiers feature RCA preamp outputs which can be used to signal feed secondary amplifiers in your system without the use and expense of "Y" adaptors. The preamp output is full range.
USING THE BUILT-IN LOW PASS ELECTRONIC CROSSOVER
All the RS amplifiers feature 24dB per octave fully adjustable
Set the frequency adjustment knob marked LOW PAS FILTER to adjust the filter frequencies.
SUBSONIC FILTERING.
Your RS amplifier is capable of subsonic filtering. This feature is useful for today's popular bandpass or vented subwoofer enclosures. The subsonic filter acts as a High Pass crossover blocking the unwanted signals from reaching specific speakers. This helps to control the mechanical excursion of the woofers at very low frequencies, thus causing a cleaner sound, better utilization of amplifier power and improved speaker reliability.
PHASE SHIFT CONTROL
The Phase Shift control on the RS amplifiers allows you to adjust acoustical integration between the sub bass and higher frequency speakers in a system. Adjust this control for best audible results.
AMPLIFIER MODE SWITCH
This switch enables you to slave multiple RS amplifiers off one master. Set it to MASTER for single RS amplifier, or first of a multiple RS amplifier systems. In multiple RS amplifier systems, set this switch to SLAVE for any amplifiers slaved off a master.

ADJUSTING THE SYSTEM
Once the system is operational, the first thing to do, is set all crossover points to approximate settings. In the case of the basic system described on Page 6, start off with the RS amplifier Low Pass filter, and the highs 2 channel amplifier’s internal crossover at 100 Hz or so. Set all equalizer controls to 0 dB
Now you should set the amplifiers LEVEL adjustment. The knob accessible on the top of the amplifier marked Input Level adjusts the input sensitivity from 200mV to 9Volts.
To adjust the input sensitivity, turn the control using a small flat head screwdriver fully counter clock wise to the 9volt minimum position. Do not apply any pressure while turning as this might break the control unit. Adjust your radio volume level to maximum volume. Now turn the level control on the amplifier clockwise towards 200mV marking and until audible distortion occurs. When you begin to hear any distortion in the sound back down one notch and your amp is set. It is helpful to have a second person to help you set the gain.
When setting up a
Once you’re satisfied with the level control settings, use the equalizer controls to adjust the system tonal level for personal preference. Keep in mind that after equalizing, you may have to go back and reset the level controls.
The level control of any car amplifier should not be mistaken for a volume control. It is a sophisticated device designed to match the output level of your source unit to the input level of the amplifier. Do not adjust the amplifier gain to maximum unless your input level requires it.
If your unit has been professionally installed please do not change the gain settings set by the installer, he is the professional!
Your system can also be extremely sensitive to noise when the LEVEL is set to maximum and does not match your input signal. The gain adjustments need to be made only once when first setting up the system.
