Dee-Eye Musical Instrument Preamplifier^TM

The Dee-Eye Instrument Preamp offers a simple solution for connecting instruments with high-impedance piezoelectric pickups to a venue’s sound system. Any passive or active instrument pickup is supported.

The Dee-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 Dee-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 5 volts peak-to-peak level.
• Low-impedance, balanced, XLR output, 600 ohms, will drive long cables to a mix-board.
• Requires XLR Phantom Power.
• Power OK Light is on when preamp is properly powered up.
• 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 1.5 x 3.75 inches. Weight: 6 ounces.

Dee-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 18K Hz.

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

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

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

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

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

• Add any effects boxes you want in series between the Dee-Eye Preamp and the PA.
• An XLR cable must be connected to supply Phantom Power

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

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