Fire-Eye RED-EYE INSTRUMENT PREAMPLIFIER Manual

Red-Eye Instrument Preamplifier
The Red-Eye Instrument Preamp offers a simple direct-connect solution for musicians
playing instruments with high-impedance piezoelectric pickups. The Red-Eye Preamp
works well with instruments having passive or active piezo pickups or those with magnetic
pickups such as electric guitars and electric basses.
The Red-Eye Preamp's impedance-matching field-effect transistor input circuit is designed
especially to match and track the impedance of passive piezoelectric pickups. That results
in a smooth, natural, balanced, acoustic instrument tone. Low distortion, low noise, and
generous headroom mean that clear tone comes through even when an instrument is
played percussively and loudly.

Features:


Input: Impedance-matching, accepts up to 2 volt peak-to-peak level without distortion.

Low-impedance, balanced, XLR output, 600 ohms with ground-lift switch,

Boost button with volume control for amplifying solos.

Treble control to boost or reduce treble. Response is flat when control is centered.

Usually powered by 48-volt XLR phantom power but has an internal 9-volt battery and a 9
to 18-volt center-negative, center-ground, power jack as alternatives.

Long 9-volt battery life (~200 hours). Battery is not used if other power is present.

Plugging an instrument in or connecting external power turns the Red-Eye on.

Pwr Chk Light illuminates for about a second if power is good when the preamp is
powered up. When powered up on the battery, the light will appear if the battery is in the
first ¾ of its life.

¼ inch output and input for effects accessory loop, suitable for stomp-tuners or effects
pedals or for output to on-stage guitar amps or PAs.

Internal filtering to reject radio-frequency interference from neon lights and cell phones.
