1.1. INSTRUMENT IN: An unbalanced input for the connection of 1/4” jacks, with optimal sensitivity
for high level signals. The electronics will adapt to any situation - no special action is required.
1.2. 10V: This supplies the jack connector with 10 VDC for powering electret microphones.
1.3. GAIN: This variable gain preamplifier adjusts the sensitivity level to ensure the best possible
processing of the signal through the channel. It is important that this input level is set and optimized
in the best way to achieve the cleanest sound possible.
1.4. OVERLOAD: This LED (when lit) indicates that the level of the input signal is too high and it
might therefore introduce distortion.
Practical tip: When using an amplified speaker, distorted input signals should be avoided at all cost
in order to prevent potential damage to the speaker. While playing your instrument, carefully set the
preamp/gain level by turning up the GAIN control until the OVERLOAD LED begins to blink. At this
point, turn the gain back down slightly. Now set the MASTER Volume between 30% and 60%. With
the gain and master levels appropriately set, you can now set the channel volume as you please.
1.5. WARM: When active, this low-pass filter dampens higher frequencies to produce a warmer
sound when using bridge-mounted pickups such as the SCHERTLER STAT Series for violin, cello and
double bass.
1.6. HIGH, MID, LOW (EQ): These controls are for high, mid and low frequency regulation. Offering
cut and boost of ±15 dB, they allow a wide range of tonal variations to be explored. When the
controls are positioned centrally there is no cut or boost of the selected frequency band.
1.7. REVERB: This rotary control sets the level of the digital reverb on the channel.
1.8. VOLUME: This rotary control regulates the channel volume.
