INTRODUCTION
Congratulations on purchasing ROY - Schertler Group’s new top-of-the-range combo
amplier 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 ampliers, 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 amplication 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 largerscale 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.

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 amplier’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 modied for balanced XLR use.
For any doubt, please contact us to check the compatibility of your audio device before using the amplier
1.4. GAIN
This variable gain preamplier 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
This rotary control sets the level of the digital reverb on the channels
1.9. VOLUME
This rotatory control regulates the channel volume
