C-ducer B1000 Instructions - page 2
THE
C-DUCER
TAPE
The C-ducer [Capacitive-trans-ducer] is a contact condenser microphone. It is light in
weight so as to minimise interference with the vibration of the instrument to which is
attached, and it has a phenomenal dynamic range [the transducer
itself has a dynamic capability of >155dB] and can handle the amplitudes within a bass
drum without distortion. The frequency response of the transducer is an incredible 0.1Hz
to 1MHz, although this is deliberately restricted within the preamplifier to minimise noise
and interference.
Two lengths of C-ducer tape are available, 3" [7.5cm] and 8" [20cm]. The shorter length is
suitable for smaller instruments [violin, folk harp, banjo etc], and the longer tape is
designed for other acoustic stringed instruments [double-bass, cello, acoustic guitar etc],
drums and piano.
The B2000 C-ducer piano system uses two 8" tapes.
THE C-DUCER PREAMPLIFIER The C-ducer B2000 uses a low-noise preamplifier which
has been integrated into the extended jack connector. The output from this connector is
suited to any standard jack input amplifier, combo, or recording desk.
The B1000 is powered by a built-in lithium battery which has a minimum life of 1000 hours
continuous use. When a replacement battery is required, the new battery must be one of
the C-ducer type CR1 and should be fitted with care.
CARE OF YOUR C-DUCER
C-ducer is a rugged instrument; however, certain precautions should be taken to ensure the
many years of trouble-free use it has been designed to give:
ã
The C-ducer should never be punctured or cut.
ã
Although the C-ducer is designed to be splashproof, it should not be deliberately
immersed.
ã
The C-ducer should only be powered by the batteries as supplied by the manufacturer.
ã
The C-ducer should only be attached to the instrument using adhesives outlined on Page 3.
ã
If it is necessary to reduce the cable length of the C-ducer, the instructions in the
section should be noted:
CHANGING
THE
BATTERY
Only use Battery Type 3V lithium CR113N
The B1000 has a minimum life of 1000 hours {typically 1800} therefore the battery will not
need changing that often. The battery should only be changed by someone experienced in
soldering. The following steps should be taken:-
1. Unscrew cable restraints clockwise.
2. Remove crosshead screw and slide out circuit board, by pulling gently on the red jack
locking switch.
3. The battery is located at the cable end of the circuit board. To remove the battery unfold
the metal tags either side of the battery and pull the old battery gently from the circuit
board. Push the tags from the new battery through the slots on the circuit board (checking
polarity) and fold the tags flat to the circuit board. The battery should sit centrally within
the circuit board cut out.
4 To reassemble reverse points 1 to 3.
A battery kit is available from your C-ducer dealer.
