TECHNICAL SPECIFICATIONS

APPLICATIONS

Our low noise integrated circuit Class A pre-amplifier has been specifically designed to overcome the problems often encountered with amplification of Acoustic Instruments fitted with ceramic transducers. A frequent cause of these problems is the mismatch of level and impedance in the electrical circuit between the pickup and the amplifier: this mismatch has been completely eliminated with the introduction of our Acoustic Instrument Preamp/ D.I Unit.

The pickup output should be connected directly to the Preamp input with a short, low loss, screened cable; the Preamp output can now be fed to any effects or volume pedals (if used) and then on to the amplifier. The Preamp gain control should be adjusted to a comfortable signal level with the amplifier volume control set to about 50%. Alternatively the gain can be set to match the signal level of another instrument (e.g. Electric or Bass Guitar) when they are both fed into the same amplifier.

Players of Acoustic (Double) Basses will find their previous problems with lack of low frequencies; poor sound when playing Arco; poor sound with volume or other pedals; poor response to double stopping; poor D.I. sound etc. etc. will be completely eliminated when our Preamp is used.

The D.I. output is a transformer coupled low impedance source on a male XLR connector. Pin 2 is in phase with the preamp input; pin 3 is reversed phase and pin 1 is the ground connection.

Also fitted is an auxiliary output, which may be used to feed a signal to a Tuner; this signal is identical to the main Output signal.

DIMEMSIONS: 145 X 95 X 49 mm

POWER SUPPLY

An input for a 9v DC supply is fitted: the size of the coax connector is 5.5/2.1mm and the centre pin is negative (-VE).
The voltage rating of the adapter should be noise free, fully stabilized at 9V DC and capable of supplying 20mA. We recommend the use of the Voodoo Lab Pedal Power 2 Plus power supply as meeting the above criteria and cannot accept any liability for damage caused to this unit by the use of, or to, any other type of AC/DC adaptor. An adapter proving an output of an AC voltage should not be used as it will permanently damage the pedal: such damage is not covered under out warranty. If only a single unit is to be powered the BOSS PSA series may be more cost effective and is also recommended: but do not "Daisy Chain" other effects if using this adaptor as this may cause hum problems.
