pT2-500 Microphone Preamplifier

OPERATION MANUAL

Version 1.0

CAUTION:
We recommend that you avoid “hot-patching” microphone inputs when using
a patch bay at the microphone inputs of the

pT2-500. Please TURN OFF

phantom power and turn down the gain prior to connecting or re-patching
microphone inputs routed through a patch bay. Failure to do so may result in
transients that can damage the

pT2-500 or equipment that is connected to

its outputs-not to mention your ears!

Instrument Input and Thru (DI)
1. Connect your instrument cable to IN. This interrupts the microphone input on the rear

panel and routes your instrument to the discrete FET DI in the

pT2-500. This input

is intended for unbalanced signal sources.
 DO NOT use TRS plugs for this input or the DI will not be activated 

2. If desired, connect a cable from THRU to a guitar/bass amp, another DI, or additional

signal processing device.

3. The IN and THRU jacks are directly connected as in any typical standalone DI. Since

the input impedance of the

pT2-500 FET DI is 2.5 Megohms, it does not provide

any significant electronic load to the instrument pickup. When connection is made via
the THRU jack to an amp or other device, the input impedance of that device will
essentially determine the electronic load on the instrument pickup. Keep in mind that
lower impedance may alter the tonal character of your instrument.
