INPUT/OUTPUT
7. 5 VDC Power Adapter (optional)
Although the Tracker Pre is normally bus-powered via USB, it can also be
powered by an external 5-Volt DC power adapter (optional) to allow it to be
used as a stand-alone stereo microphone preamplifier.
NOTE to PC Users:
When using a USB 1.1 port,
performance is limited to
16-bit and 44.1/48 kHz
recording and playback.
(USB 1.1 is not supported
on the Macintosh.)
8. USB
Connects the Tracker Pre to your computer via the supplied USB cable. The
USB connection provides two-way communication when connected to the
computer.
Since the Tracker Pre receives its power from the USB, always connect to the
USB jack on the computer itself and NOT to a low-power USB connection
that may be present on your computer keyboard or other USB peripheral.
9. Main Outputs (1L & 2R)
The balanced outputs are normally connected to your monitoring system.
Either balanced or unbalanced cables may be used. The main output volume
can be controlled using the System Volume Control on your Mac or PC. Many
“multimedia” computer keyboards contain System Volume Controls.
10. Phantom Power on/off
This switch turns 48V Phantom Power on or off to the XLR inputs for use with
microphones which require phantom power. See
to learn more.
11. Inserts (1L & 2R)
These unbalanced TRS jacks allow you to insert a signal processor, such as a
compressor or EQ, after the mic preamps, but before the A/D converter stage.
See “Insert Connection Example” on page 13.
The Insert jacks can also be used to tap off the mic preamp outputs when
using the Tracker Pre as a stand-alone stereo microphone preamp. Page
12. Hi-Z / Line / Mic Inputs (1L & 2R)
Use the XLR connector for microphones or balanced line level signals. Use the
1/4¨ jack in the center of the XLR connector as a Hi-Z input for guitar/bass, or
as a line level input. The inputs are balanced, but they accept either balanced
or unbalanced input signals. See
for additional information.
13. Stereo Mic Input
This 1/8” mini-phone jack is designed to accept a stereo, electret condenser
microphone. The jack supplies +5VDC phantom power. Mono microphones
can also be connected and will use input 1L.
• Note: The Stereo Mic jack takes precedence over the Hi-Z/Mic/Line inputs.
Inserting a 1/8” plug disables the other inputs.
