Thank you for choosing the ROY X amplier. ROY X represents the state of the art in Swiss amplier
design, reecting all the needs of the user. Offering a signicantly improved power amp and speaker
section, together with a crossover lter network, limiter and gain, this versatile 7-channel combo
amplication system offers 450 W (124 dB SPL) of bi-amplied power. Equipped with a 1” dome
tweeter and two 8” woofers, it has been engineered with an optimized 2-way bass reex system.
ROY X is highly effective as a stand-alone portable system for soloists or small groups. The system
can accommodate various mic/instrument combinations and offers a comprehensive mixing facility
for easy on-stage setup. ROY X’s master section includes both a spring-like reverb with decay and a
digital multi-effect module (on a separate bus). A headphone preamp provides a handy monitoring
facility.
SCHERTLER amps feature a sophisticated Class-A preamp with no integrated circuits and No
Negative Feedback (NNFB), resulting in unparalleled dynamics and fast transient behavior.
To make the most of your ROY X amplier and to ensure trouble-free operation, please read this
manual carefully before using the amp for the rst time. We also advise keeping the manual for
future reference.

IMPORTANT SAFETY
INFORMATION
SAFETY FIRST!
Safety is of major importance when operating any electrical equipment,
so please note the following:
On a product, a lightning ash within a triangle indicates the presence of
uninsulated “dangerous voltage” within the product enclosure. This may
be of sufcient magnitude to cause risk of electric shock.
ELECTRICAL SAFETY
Before connecting your amplier to the mains, make sure that the mains voltage does not
exceed the voltage specied on the device.
Do not use your amplier if its mains cable or plug are not in perfect condition. Replace these
as necessary. The replacement cable must be the same as the original.
Your amplier should only be connected to a mains socket with a ground protection system.
When using or installing your amplier, make sure that the mains socket and the amplier’s
mains cable and plug are easily accessible.
Do not, under any circumstances, defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the other. A grounding-type plug
has two blades and a third grounding prong. The wide blade and third prong are provided
for your safety. If the supplied plug does not t your mains socket, consult an electrician for
replacement of the obsolete socket.
Do not expose your amplier to rain or any other water (even in small amounts). Do not use
the amplier near water.
Avoid spilling drinks or any other liquids on the amplier.
Do not operate your amplier in excessively humid conditions. Avoid excessive heat from
sunshine, re or similar. If the amp is being used in a dusty environment, make sure it is
adequately protected.
Avoid using or installing your amplier near any heat sources such as radiators, heat registers,
stoves, or other heat-producing apparatus. Do not put any sources of open ame (e.g. candles
or pyrotechnics) on or near the amplier.
Do not cover your amplier during use, or obstruct the ventilation ow in any way.
Always leave sufcient clearance between the heat sink and any other surface.
Unplug your amplier during lightning storms, or if it is not going to be used for a while.
(Remove the plug from the mains socket to completely disconnect the amplier.)
Your amplier does not contain any “user serviceable” parts. Servicing and/or repairs should
only be carried out by qualied personnel. See MAINTENANCE AND REPAIR.
5
OPERATIONAL SAFETY
During live performances or installation, make sure that your amplier’s mains cable cannot be
walked on, tripped over or “pinched” – particularly at sockets, around waste bins etc.
To avoid interference, do not use or install your amplier near power transformers, TV sets, RF
transmitters, electric motors, or any other sources of electrical energy.
To avoid potential accidents, only use attachments, accessories and other equipment such as
carts, stands, tripods, brackets or cases that are specied or recommended by the manufacturer,
or sold with your amplier.
Loud volume levels can cause irreparable damage to both the device and your hearing, so
avoid the following while using your amplier:
- acoustic feedback (never point microphones directly at a loudspeaker)
- high levels of distortion
- impulse noises (loud “pops”) that can occur when a device is switched on/off, connected to
or disconnected from a system.
MAINTENANCE AND REPAIR
Your amplier can be carefully cleaned, as necessary, using a dry cloth. Do not use water.
When cleaning, do not use any solvents (such as acetone or alcohol). These could damage the
amplier’s nish and its labeling.
Visually check your amplier on a regular basis for any signs of wear and tear or damage, but
do not attempt any kind of servicing or repair.
If your amplier malfunctions, or is damaged, e.g. if liquid has been spilled or objects have
fallen inside, the amp has been exposed to rain or moisture, does not operate normally, or
has been dropped, please call your nearest SCHERTLER technical assistance center. (For more
information, you can contact us at the address on the last page of this manual.)

2.1. MIC INPUT (XLR): This input is electronically balanced for XLR-type connections. The channel is
designed for any kind of microphone source e.g. dynamic and condenser mics.
2.2. 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.
2.3. INSERT: This stereo jack socket enables the connection of an external device (compressor,
equalizer, etc.) in series to all the outputs.
2.4. 48V: Phantom power supplies the XLR connector with 48 VDC for powering condenser
microphones. Most condenser (and dynamic) mics, and some preamps, can be safely phantom
powered. In certain cases however, phantom power can cause damage. This tends to happen with
unbalanced microphones, preamps, or stompboxes that have been modied for balanced XLR use.
If in doubt, please contact the manufacturer to check the compatibility of your audio device before
using the amplier.
2.5. 10V: This supplies the jack connector with 10 VDC for powering electret microphones.
2.6. GAIN: This variable gain preamplier adjusts the sensitivity level to ensure the best possible
processing of the mic/instrument 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.
2.7. 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.)
2.8. RESON: The RESONANCE (notch) lter cuts the frequency of 150 Hz/240 Hz, to reduce low-
frequency feedback. Left: no attenuation (at), Right: maximum attenuation.
2.9. RESON button: Use the RESON button to select the resonant frequency of the instrument
(240 Hz/150 Hz).
2.10. 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.
2.11. MULTIEFFECT: This rotary control sets the level of the selected effect on the channel.
2.12. 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.
2.13. VOLUME: This rotary control regulates the channel volume.
1.1. MIC INPUT (XLR): This input is electronically balanced for XLR-type connections. The channel is
designed for any kind of microphone source e.g. dynamic and condenser mics.
1.2. INSERT: This stereo jack socket enables the connection of an external device (compressor,
equalizer, etc.) in series to all the outputs.
1.3. 48V: Phantom power supplies the XLR connector with 48 VDC for powering condenser
microphones. Most condenser (and dynamic) mics, and some preamps, can be safely phantom
powered. In certain cases however, phantom power can cause damage. This tends to happen with
unbalanced microphones, preamps, or stompboxes that have been modied for balanced XLR use.
If in doubt, please contact the manufacturer 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 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.
1.5. 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 amplied speaker, distorted input signals should be avoided at all cost
in order to prevent potential damage to the speaker. While playing or singing, 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.
1.6. 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. Parametric
MID regulation offers the possibility to cut or boost a frequency range between 300 Hz and 3.3
kHz. 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 channel.
1.8. 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.
1.9. VOLUME: This rotary control regulates the channel volume.

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 preamplier 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 lter 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 amplier is muted.
6.4. LOW CUT: When active, this lter 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 amplier 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).

FAQ
Amp bags, along with other SCHERTLER product
accessories, are available from the online web
shop at www.schertler.com. You can buy the
product itself and/or its accessories from the
relevant product page.
Digital versions of our manuals are available in
English, Italian, German and French. These can
be downloaded from the product pages of the
SCHERTLER website: www.schertler.com
No, our amplier electronics are designed
for mains use only. It is not possible to modify
the amp for “battery powering”. You could
however connect the amp to an external voltage
compatible battery that can accommodate the
amp’s supplied power cable/plug.
Yes, the INSERT connection works on the
Master, so it affects all the channels.
The easiest way to connect an external speaker
(or a second active amp) is via the LINE OUT
or DI OUT.
If you only have one instrument connected
to your amp, you can use the master section
INSERT. For this connection you will need a Y
insert cable. Another way of connecting the
external effect is in series: the effect must be
in the chain just before the signal enters the
amp (guitar —> pedal —> amp). A third option
(maybe the best) is to use the amplier’s AUX
OUT. This is the parallel send that sends the
signal to the internal reverb as well. By using
the AUX OUT you can feed your delay input
and continue using the internal reverb. The
channel effect send will be the same for both
the external effect and the internal reverb. You
will be able to set the amount of the effect/
reverb using the returns.
Where can I buy amplier bags/accessories?
Can I get a copy of this manual in other
languages?
Can I bypass the internal power supply and
power the amp via battery?
Does the I/O INSERT allow you to put effects
on all channels?
How do I make the connections to use a second
speaker or amplier?
What is the best way to connect a delay or
other external effect to my ROY X?
