Red-Eye Musical Instrument Preamplifier^TM

The Red-Eye Instrument Preamp offers a simple, one-box, direct-connect solution to musicians playing instruments with high-impedance piezoelectric pickups…for example, the L.R. Baggs violin bridge pickup. Any passive instrument pickup is supported.

The Red-Eye Preamp’s high input-impedance allows piezoelectric pickups to operate essentially unloaded, which results in a smooth, natural, acoustic instrument tone. Low distortion, low noise, and generous headroom mean clear tone comes through even when an instrument is played percussively and loudly.

The Red-Eye Preamp also works well with instruments that have magnetic pickups, such as electric guitars and electric basses.

Features:

• Input: high-impedance, greater than 1 million ohms, maximum 1 volt peak-to-peak level.
• Low-impedance, balanced, XLR output, 600 ohms, will drive long cables to mix-board.
• Boost button with volume control for amplifying solos.
• Treble control to boost or reduce treble.
• Long 9-volt battery life (~200 hours).
• Automatic battery check: OK Light flashes for 1 second when preamp is powered up.
• Automatically uses XLR Phantom Power, when available, instead of the battery.
• ¼ inch output and input for accessory loop, suitable for stomp-tuners or effects boxes or for output to on-stage guitar amps or PAs.
• Internal filtering to reject radio-frequency interference from neon lights and cell phones.
• Small Size: 1.25 x 2.25 x 4.25 inches. Weight: 10 ounces.

Red-Eye Preamp Signal Path:

· The Instrument Input impedance is over 1,000,000 ohms.

· The Effects Loop Output impedance is less than 4,000 ohms.

· The Effects Loop Input impedance is 4,000 ohms.

· The XLR Output impedance is 600 ohms.

· Frequency response is flat from 25 Hz to 18 KHz when Treble Control is centered.

· Boost level above no Boost: Minimum Boost = +4 db, Maximum Boost = + 9 db

Using the Red-Eye Preamp to simply connect your instrument to a club’s sound system:

• You have control over your instrument’s treble.
• You have control over solo boost if you need it.

Using a “Stomp Tuner” with the Red-Eye Preamp:

· When you turn on the Stomp-Tuner, the XLR output to the Mix Board will be muted.

Using several effects boxes or a pedal board with the Red-Eye Preamp:

· Connect Effects Boxes and/or a Stomp-Tuner in series to the Red-Eye Preamp Effects Loop.

· Effect Boxes and/or Stomp-Tuner will affect the XLR output to the Mix Board.

Using the Red-Eye Preamp with an on-stage Guitar Amp or Instrument PA:

• Red-Eye Preamp works to control the instrument’s treble and gives you a solo boost button.
• Add any effects boxes you want in series between the Red-Eye Preamp and the PA.

Using the Red-Eye Preamp to convert a Single-Ended signal to XLR Balanced Output:

• The Red-Eye can also be used as a high-quality passive direct box. The isolation transformer used in the Red-Eye Preamp has a nearly linear response from 18 Hz to over 30 KHz.
• Power is not required
• 4,000 ohm input-impedance, single-ended input
• 600 ohm output-impedance, balanced output
