LEVEL SETTING
The input levels are adjusted by means of the 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 Signal to Noise ratios even with low output sources.
In the ideal situation, all components in the audio system reach maximum undistorted output at
the same time. The reason is because an amplifier will only make what comes into it bigger.
So, if you send it a distorted signal from the head unit, it is going to amplify distorted
information. The same thing 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
Reference705s, follow the below procedure for the quickest, easiest means of setting the
levels.
1. Turn the amplifier's input levels to minimum position (fully counter-clockwise).
2. Set source unit volume to approximately 3/4 of full volume.
3. While playing dynamic source material, slowly increase the amplifier’s input level until a
near maximum undistorted level is heard in the system.
NOTE: Your best combination of output and Signal to Noise ratio will
be achieved when the input levels are set between 500 mV and 5.0 V.
