Schertler Unico User manual

UNICO

Please read this manual carefully before operating the UNICO.
Keep the manual for future reference.
Pay due care not to pour liquids on the device, nor operate it in excessively humid conditions.
Do not install the UNICO near sorces of intense heat, expose it to direct sunlight, nor position it in dusty evironments
without protection.
Ensure that the supply voltage is not higher than the one stated on the Rear Panel.
To prevent any induced disturbance in the UNICO, do not install near transformers, TV sets, RF transmitters, electric
motors or any source of electric power.
Never use the equipment if the cable or the electrical plug is damaged (if necessary change them or have them careful-
ly repaired).
Do not direct the microphones towards the speakers as this could cause acoustic feedback wich could damage the loud-
speakers.
To avoid damage, only use the original connection cables.
Never connect any output and input channels of the device. It could create dangerous loops.
Never use solvent based cleaning agents, such as acetone or alcohol to clean the equipment, as this will damage the
external finish and the printing on the panels.
In case of malfunction of any device in the system, contact the nearest SCHERTLER® technical assistance or a speciali-
zed center. Do not attempt repairs yourself.
After two years spent monitoring the market, SCHERTLER® decided to improve the already successful Unico
to meet our users’ needs even more effectively. Unico has made its success through its versatility and mat-
chless natural sound. Now, we have further increased the amplifier’s flexibility, adding some important fun-
ctions. By changing the size and shape of the amplifier, we have achieved a tighter, more focused bass
response. We have introduced a gain control function across the channels for improved input level control –
this is vital for a clean signal. Individual channel gain controls allow maximum flexibility to easily match
various input signals. Mid control has been added to the DYN and STAT channels and a four-band equalizer is
now available in the MIC channel to suit the needs of demanding musicians. More compact and lighter, now
Unico is even easier to carry!
150W + 35W RMS, in combination with a biamplified system, guarantee total transparency, harmonically rich
sound and full low frequency control (down to 40Hz).
Compare Unico with the competition and you will appreciate the difference!
The SCHERTLER® Team.

MIC CHANNEL: This channel enables the connection of a condenser microphone, by activating the 48V button – or dynamic microphone.
STAT CHANNEL: This channel enables, for example, the connection of a guitar equipped with a BLUESTiCK® series system.
DYN CHANNEL: This channel enables, for example, the connection of a BASIK electrostatic microphone to amplify just any acoustic instrument.
INSERT: For easier volume control, you can use the “UNICO VOLUME CONTROL PEDAL” via the INSERT function.
AUX SEND: For increased volume or wider coverage o, connect an active (powered) extension speaker such as the SCHERTLER SIDE
(180W) or PUB 280 (280 W) active loudspeaker and adjust output volume using the AUX SEND potentiometer. Alternatively, if you
wish to record your music, connect your recorder to the same output and start recording.
DI OUT:Signal can be sent to another mixer, for example SCHERTLER’s OPERA mixer.
LINE OUT:For use with bass or keyboards or to increse overall bass response, SCHERTLER® strongly recommends the use of a sub-
woofer such as the SCHERTLER® BASS200 or PUB380. Connect the LINE OUT to the INPUT of the sub-woofer, press the LOW CUT on
the UNICO, for a three-way (triamplified) system.
CONNECTING YOUR BLUESTICK
All BLUESTiCK® models (except for MARINE series) can be connected to STAT and DYN inputs with the 10V switch OFF.
BLUESTiCK® MARINE: Connect to STAT input with the 10V switch ON.
CONNECTING HIGH-IMPEDANCE SIGNALS (piezos, magnetic pick-ups and similar sources)
To connect any passive piezo transducer or magnetic pick-up, use “Active Driver Cable” and connect to the STAT input with
the 10V switch ON. The high-impedance cable is also used to connect electric guitars and bass guitars with magnetic pick-ups.
