INTRODUCTION
BC-1 Bass Crunch floor Bass Guitar preamp is intended for use both in studio
and live on stage.
Working at BC-1 the
АМТ
Electronics experts developed new original circuitry
solutions using JFET-based tube stages emulation resulting in clean, overdriven or
mixed quality sound with minimum power consumption.
Flexible sound adjustments and wide variety of switching possibilities will allow
you to obtain your sought-after sound practically anywhere. Thanks to the device
compactness and lightness you can carry it in a gig bag side pocket or a bag.
Bass crunch BC-1 preamp is based on a two-channel circuit.
CLEAN
channel shapes the classic bass guitar sound characteristic for «old»
amplifiers and allows both velvet transparent sound and slight compressed overdrive
depending on the position of Gain control.
DRIVE
channel contains a number of over amplification stages and is intended for
obtaining the modern sound from clean to totally overdriven one. The High Mode
provides additional possibilities in terms of the range enrichment towards higher
sound density and aggressiveness. The adjustable 3-position mid-range filter
combined with deep adjustments along the frequency ranges offer a musician its rich
possibilities related to shaping of the overdriven tone range.
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.
SPECIFICATIONS
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.
