[TRIM] control

PEAK LED

The analog signal received at each input ([INPUT A] through [INPUT D]) is sent to the [TRIM] control, by which the signal level fed to the A/D converter of the MR-8HD/CD is controlled.

You can check this level by the PEAK indicator. If the level is too high, the PEAK indicator lights, while you may hear the sound distorted or noisy. This distortion (noise) generated at this stage cannot be eliminated, therefore, adjust the TRIM control properly so that the PEAK indicator does not light at the loudest part of the input signal.

Proper level The level is too high.
