3.1. 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.
3.2. PHASE: In the event of feedback, or unwanted effects between channels, use the PHASE
REVERSE button.
3.3. 10V: This supplies the jack connector with 10 VDC for powering electret microphones.
3.4. 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.
3.5. OVERLOAD: This LED (when lit) indicates that the level of the input signal is too high and it
might therefore introduce distortion. (See “Practical tip”, 1.5.)
3.6. 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.
3.7. 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.
3.8. MULTIEFFECT: This rotary control sets the level of the selected effect on the channel.
3.9. REV/AUX: This rotary control sets the level of the digital reverb on the channel and the level
of the signal to the AUX OUT output. If you want to bypass the onboard reverb, you can set the
REVERB Master control to zero and use the REV/AUX to control the amount of signal you want to
send to an external effect unit, or to an additional monitor.
3.10. VOLUME: This rotary control regulates the channel volume.
4.1. STEREO IN: 1/8” mini jack stereo input for PC, MP3 and other electronic devices. Volume
depends on the MASTER volume regulation.
5.1. FX RETURN: Left and Right unbalanced jack socket for the return of external effects. This can
also be used as a 7th input channel to accommodate an extra line level device.
5.2. FX RETURN VOL: This rotary control regulates the channel volume.
4.1 5.1
5.2
6.1. MASTER: Controls the overall system volume.
6.2. MUTE: This cuts the audio on the Master.
6.3 MUTE LED: This LED indicates when the amplifier is muted.
6.4. LOW CUT: When active, this filter cuts all frequencies below 120 Hz - ideal if you play an
instrument that generates aggressive low frequencies. It enables you to connect a subwoofer, and
prevent unwanted vibration and possible damage to your ROY X.
6.5. Power LED: This LED indicates when the amplifier is switched ON.
6.6. DI OUT: A general XLR balanced output for connecting to external systems. The output volume
does not depend on the regulation of the MASTER control, but is affected by changes in individual
channel volume.
6.7. DI OUT Volume: This rotary control sets the output level on the DI OUT.
6.8. AUX OUT: Additional output. This mono jack socket enables connection to other systems. In
order to create a secondary mix for a stage monitor or external effect, turn the REVERB Master
control (6.14) to zero and use the REV/AUX control on each channel to set the levels. You can
still have an internal reverb effect from the MULTIEFFECT (use the MULTIEFFECT control on each
channel to set the desired amount of internal effect).
