INTRODUCTION
Congratulations on purchasing ROY - Schertler Group’s new top-of-the-range combo amplier for acoustic
instruments. This 400W, 7-channel amp provides a powerful yet comparatively lightweight system that is
perfect for both stage and studio. Equipped with a 1” horn, two 8” subwoofers and featuring the same hi-
end Class A preamp found in other Schertler ampliers, ROY delivers the rich, high-quality sound that has
become synonymous with this product family, while providing the user with even greater exibility.
ROY has 4 input channels with various mic / instrument combinations, inserts (as on a professional mixer),
3-band EQ and phantom power; an additional unbalanced instrument input channel; a stereo input channel
for playback devices and an FX return / additional input channel. ROY’s Master section includes both a
digital reverb with decay and a new digital Multi-Effect (on a separate buss). This intuitive control surface
provides a comprehensive mixing facility for easy set-up and on-stage adjustments during performances.
Highly effective as a stand-alone portable amplication system for soloists or small groups, ROY also
offers a range of output options for connecting to external systems: Add a separate subwoofer to enhance
the low frequency ranges of certain instruments, or to create a compact 3-way active PA system. Connect
to a mixing console for larger-scale applications. The addition of a headphone preamp provides a handy
monitoring facility for both live performance and recording applications, making ROY a powerful and
practical “all rounder”.
On the following pages you will nd a more detailed overview of ROY’s control surface.
PRACTICAL ADVICE
When you are using an amplied speaker, one of the most important recommendations is to avoid at all
costs a distorted input signal.
In other words, when you are controlling the sound in your amplier’s mixer section (or any other
preamplier), you must avoid reaching saturation level.
While playing your instrment or singing in the microphone, start turning up the Gain knob until the Overload
LED begins to blink. At this point, turn the Gain knob back down slightly. This correctly sets the preamp
level depending on your actual input signal. 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.
In the case of amplied speakers, the arrival of a distorted signal (square wave) may damage the internal
amplier beyond repair, which may in turn damage the loudspeakers.
Correct use of speakers guarantees their long life.

1.1. MIC INPUT
This input is electronically balanced for XLR type connections. The new MIC/DYN channel is now conceived for any kind of signal
sources. You can plug in vocal microphones. The electronics will adapt to any situation. No special action is required
1.2. INSERT
This stereo jack plug enables the connection of an external device (compressor, equalizer, etc.) in series to all the outputs
1.3. 48V
The amplier’s XLR input provides 48V phantom power for use with a condenser microphone. Most condenser (and dynamic)
microphones, along with some preamps, can be safely phantom powered. In certain cases however, phantom power can cause
damage to a device.
This tends to occur with unbalanced microphones, preamps or stompboxes that have been modied for balanced XLR use.
For any doubt, please contact us to check the compatibility of your audio device before using the amplier
1.4. GAIN
This variable gain preamplier adjusts the sensitivity level to ensure the best possible processing of the MIC signal through the
channel.
It is important that this input level should be set and optimised in the best way to achieve the cleanest sound possible
1.5. OVERLOAD
This LED (when lit) indicates that the level of the inputsignal is too high and it might introduce distortions
1.6. HIGH, MID, LOW
These controls are devoted to high, medium and low frequency regulation. Offering cut and boost of ±15dB, they allow a wide range
of tonal variations to be explored. Parametrics MID regulation, offers the possibility to cut or boost a frequency range between 300Hz
and 3,3kHz. When the controls are positioned centrally there is no cut or boost of the selected frequency band
1.7. MULTIEFFECT
This rotary control sets the level of the selected effect on the channels
1.8. REVERB (AUX)
This rotary control simultaneously sets the level of the digital reverb on the channels and the level of the signal sent to AUX OUT.
