INTRODUCTION

SS11A and SS-11B floor preamps are intended for use both in studio and live on

stage, for standard tuning playing as well as lower one.

Before starting the serial production of AMT SS-11 guitar preamp we conducted a

number of audio tests and experiments. As a result we arrived to the conclusion that

in order to satisfy various tastes of the guitarists army SS-11 would be produced in

at least two versions based on the same platform.

While developing SS-11 we were guided by the following concept – the quality

sound at minimum size and maximum functionality with full-bodied tube-based pre

amplification on the basis of quality electronic components.

Architecture of SS-11:

9 tube-based 4-stage overdrive channel (2x12АХ7) with high anode supply

voltage (+300V).

9 three separate CLEAN/CRUNCH/LEAD channels. CRUNCH and LEAD have

common tone controls but separate sensitivity and output level controls plus

separate Tone-SHIFT switches.

9 serial insert (FX LOOP);

9 OUTPUT channel connection to specialized guitar amps with standard level of

+10dB (TO AMP mode) as well as directly to mixing console with standard

level of -10dB with guitar cabinet simulation feature (TO MIX mode)

9 the preamp outputs are equipped with the improved semi-conductor buffers

providing not only the signal enrichment with low harmonics, but also smooth

transition to additional slight limitation inherent in devices using vacuum

triode-based insert.

9 SS-11 uses the new guitar cabinet emulator based on filed-effect transistors

possessing better natural sounding when connected to line-in.

9 the special attention was paid to the quality of triodes anode supply: the

preamp uses specially developed high-voltage transducer eliminating

penetration of amplified signal pulse interferences.

SS-11 Channels Description

LEAD offers an ample supply of overdrive and dense stringy sound great for

aggressive rhythm parts as well as melodious solos with excellent readability.

CRUNCH differs in lesser overall sensitivity and more open sound structure. The

wide range of sensitivity adjustment allows to obtain the sound starting from slight

crunch to nearly LEAD channel’s heavy sound.

CLEAN offers classic clean sound with slight limitation in maximum sensitivity mode

and crystal clear and bright one within the range of moderate sensitivity. CLEAN

channel has a separate 3-way tone control, sensitivity and output level adjustment

and BRIGHT switch.

Before You Start

To provide safe transportation the device was carefully packed by the manufacturer.

However, if the the packaging is damaged it is necessary to visually inspect the

device.

¾ If you detect any damages DO NOT ship the device to our

address but inform the vendor and transportation company,

otherwise you’ll lose your compensation right.

¾ In order to avoid damages during transportation or/and storage

use the original packaging at all times.

¾ Do not allow children to play with the device and the

packaging.

¾ Please recycle all packaging to avoid environmental

contamination.

¾ To avoid the device overheating provide enough air circulation

around it, do not cover it and do not place it next to heat

generating equipment.

¾ Using the device nearby powerful radio transmitters and high-

frequency signals sources might result in significant decrease

in sound quality. If this is the case increase the distance

between the device and transmitter and use shielded cables for

all connections.

WARNING!

Please pay attention to the fact that loud sounds might impair your

hearing or/and damage your speakers. Before switching the device

on please turn the VOLUME control knobs to extreme left position

(counterclockwise). Try to use moderate volume levels at all times.

Use only manufacturer-recommended devices and

accessories while operating the device.
