* Description

The EDB1 (Sheer Acoustic Equaliser Direct Blend) is a mega multi-purpose and compact external pre-amplifier box of pro-audio quality.

You can completely shape your sound with its five band interactive EQ, switchable input impedance and three way Range Switch, offering acoustic Guitar, Bass or Violin settings, which cut unwanted low end tones, below the useable frequency range of the instrument. This cuts body handling noise, unwanted resonaces, feedback and Violin bowing noise. Feedback and other resonance problems may be further tackled by a very effective, broad ranging tunable notch filter and a Phase Reverse control.

Inputs are via Mono Jack, Stereo Jack and XLR, via Two Channels, which enable you to blend in an extra pickup, or Microphone and you can plug into them via one or two standard mono jack leads, a jack lead plus an XLR, or a stereo jack lead.

The Input Impedance Switches on each channel, allow you to optimise the voicing for any of the major pickup types, while a huge amount of extra levels can be applied via the Gain controls and additionally by the Master Volume.

Phantom power is also available to Jack In and XLR Inputs, making the unit friendly for use with quality Condenser Mics and Instruments wired with no battery inside instrument, but with active pickups needing powering.

Outputs are via a balanced XLR D.I. out and a line out Jack. If an earth loop is heard causing hum, you may kill it by pressing the Earth Lift Switch. The two outputs also allow you to split the signal, such as between Acoustic Combo amp for stage monitoring and an out front mixing desk.

EDB-1 can be mounted on its rubber feet, carried with you on the belt clip, or mounted via a mic stand, with an optional bracket.

Powering is via two 9v PP3 ( 6F22 ) Batteries, or via plug in DC Power supply.
