Description
The EDB (Sheer Acoustic Equalizer 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 which cut unwanted low end tones, below the useable frequency range of the instrument. This cuts body handling noise, unwanted resonances, feedback and 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.
The Input Impedance Switches on each channel, allow you to optimize 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.
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.
The EDB 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.
