Red-Eye Musical Instrument Preamplifier

Red-Eye Musical Instrument Preamplifier

Description:
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, 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
