INTRODUCTION
The SS-30 guitar preamp is intended for use in studio and live performances.
AMT SS-30 is a 3-channel JFET-based tube overdrive modeling device with full
parameters visualization. The device allows for simultaneous and separate use of
two outputs to a mixer's line input and an amp's RETURN. The serial FX loop can be
used for external effect pedals connection. With external MIDI converter (e.g. AMT
FS-2MIDI) linked to the special connector the device can be combined with external
MIDI devices.
AMT SS-30 features low energy consumption from 18V DC power adapter or two
9V batteries.
SS-30 Features
- powered by two 9V 6F22 batteries or 18V DC power adapter ;
- fast and hassle-free batteries replacement without using a screwdriver;
- less than 10 mA current consumption (without external MIDI converter);
- 3 channels: Clean, Crunch, Lead
- serial FX Loop
- separate cabinet emulator output
- 3.5 mm jack to control external MIDI devices by means of AMT FS-2MIDI
SS-30 Channels Description
AMT SS-30 preamp features 3-channel design.
CLEAN
Channel has classic clean sound similar to old-time amps and provides
both velvety transparent sound and a slight overdrive depending on CLEAN GAIN
position. CLEAN Channel has separate 3-band tone, drive and level controls as well
as CLEAN BOOST switch providing more energy and presence.
CRUNCH
Channel has much higher overall sensitivity. Its wide control range along
with ample output tone control possibilities allows to obtain sounds from light airy
crunch to hard&heavy approaching LEAD Channel's density and brightness.
LEAD
Channel is distinguished by high sensitivity and provides aggressive modern
guitar sound for both standard and lower tunings. The well-saturated channel sound
is oriented to obtaining modern resilient chord punch as well as speedy licks
readability. In this way the channel can be used not only for aggressive rhythm parts
but also bright expressive solos.
To enhance tone control possibilities of the common tone control unit of
DRIVE
channels (Crunch/Lead) we incorporated DR.TONE SHIFT switch providing better
tone coordination between the preamp and your power amp and cabinet.
CAUTION! AMT preamps like any other high-class devices
are very sensitive to power adaptor quality. We insist on
your using either two 9V 6F22 batteries or an adapter meeting the
quality specifications to power your device.
Before you start
For safe transportation the device was carefully packaged by the manufacturer.
However, if the cardboard packaging is damaged you should immediately inspect
the device for the absence of external damages.
¾
In case of damages do NOT SEND the device to manufacturer,
but inform the seller or transport agency, since otherwise you
will lose the right to damage compensation.
¾
In order to avoid damages during storage and transportation
always use original packing.
¾
Do not allow children to play with the device and packaging
materials.
¾
Please, recycle all packing materials in the way harmless to the
environment.
¾
In order to avoid the device overheating provide a sufficient
airflow around it; do not cover it and do not place near other
heat emitting devices.
¾
Device operation near powerful radio transmitters and sources
of high-frequency signals can result in appreciable deterioration
of sound. In this case increase the distance between the device
and the transmitter and use screened cables for all
interconnections.
CAUTION!
Please be aware that high volume can harm your hearing and /
or damage the dynamic heads of your acoustic system. Before
turning the device on rotate Volume controls to extreme left
position (counter-clockwise). At all times try to adhere to
moderate volume level.
ТЕХНИЧЕСКИЕ ХАРАКТЕРИСТИКИ
Use only auxiliary devices and accessories
recommended by the manufacturer.
Powering the device from battery and power adapter
AMT BC-1 is powered either by two 9V 6F22 internal batteries or external
DC 18V power adaptor (the required adaptor quality specifications are shown
in Specifications section)
When using batteries the device enters ON mode only after insertion of
mono
jack into the device's INPUT.
When using DC 18V adaptor, the device is switched on after insertion of the
adaptor's connector into the device - insertion of mono jack is not necessary.
