Installation Step; Troubleshooting - Soundstream RUBICON RUBICON Class A 5.2 102 Owner's Manual And Installation Manual

INSTALLATION STEP 5

The input levels are adjusted by means of the individual channel input level
controls located on the front of the amplifier. This is a unique dual-stage circuit
that adjusts both level and gain. This topology maintains better S/N Ratio even
when using sources with minimal output.
In the ideal situation, all components in the audio system reach maximum
undistorted output at the same time. If you send a distorted signal to an amplifier,
it is simply going to amplify distorted information. The same holds true if an
outboard processor or crossover begins to distort before you have maximum
output from the amplifier. By setting all components to reach clipping at the same
time, you can maximize the output of your system. For the RUBICON amplifiers,
follow these steps for setting the input levels:
1. Turn the amplifiers' input levels to minimum position (counter-clockwise)
2. Set the source unit volume to approximately 3/4 of full volume.
3. While playing dynamic source material, slowly increase the amplifiers' input
level until a near maximum undistorted level is heard in the system.
The clipping indicators on the top of the amplifier let you know when the output of
the amplifier is reaching its maximum level, and has begun to clip.
Once the amplifier is installed and the proper levels set, place the front spoiler in
position, and secure it on using the supplied hardware.

TRIDENT PROTECTION CIRCUITRY
Your Rubicon amplifier is protected against both overheating and short circuits
by means of main power fuses and the following circuits:
Speaker Output Protection
Smart Power Supply Thermal Rollback and a Thermal Protection Circuit
the amplifier is seeing a dead short, either in the speaker wire or in
the speaker itself. Rectijl the problem before blowing multiple fuses!
DO NOT increase values beyond the original fuse value1 Doing so will
void your warrant and may damage your amplifer.
