Especially designed for use with all Schertler electrostatic and dynamic transducers, The PRE-AIII
is a compact preamplifier loaded with features with improved performance. Individual controls include Gain, Bass, Treble,
Resonance (180 Hz attenuation) and Volume.
The PRE-AIII accepts both XLR and 1/4" jack inputs, and provides both dry (line level) and equalized outputs. A phantom power switch is provided to supply power for the BLUESTiCK Marine system. The PRE-AIII is designed to allow the player to plug into a powered speaker, bass amplifier, or powered stage monitor, without any performance loss, with a separate send for the house system. Class-A constant current design and a regulated AC power supply mean a strong instrument signal at all times is delivered to the sound system. The PRE AIII features: * Combination input - 1/4" jack or balanced XLR * Two outputs: Dry - intended for the house system and unaffected by volume and EQ adjustments. Output(local) - intended for the player's monitor, or for performing using a powered speaker or bass amp only. * 12VDC input power supply input (12 VDC regulated power supply "wall wart" included) * Phantom power switch for the Bluestick Marine * Ground lift Switch The PRE-AIII controls are the following: * Gain: the mic trim (pre EQ gain - both outputs - DRY OUT and OUTPUT) * Bass EQ adjust (local output only -OUTPUT) * Treble EQ adjust (local output only - OUTPUT) * Resonance Filter adjust (both outputs - OUTPUT and DRY OUTPUT) - to cut unwanted resonance frequency * Volume (local output only) |
