The Direct Inputs (DI's) are used for connection of electric instrument

pickups or unbalanced sources such as synthesizers. The DI's we've de-
signed for the P2
acclaimed, dedicated DI products. They provide excellent articulation and
control for electric/acoustic bass, detail and smoothness for stringed in-
struments and keyboards. Simply plug the instrument cable into the front
panel DI1 or DI2 connector. When an instrument is connected to the DI
input, it overrides the microphone connection. Direct inputs DI1 and DI2
are controlled by gain controls for channels 1 and 2, respectively. Input
selections for GAIN, HPF, and Polarity (180
same manner as they apply to MIC inputs. The gain range for the direct
inputs is from 4 dB to +44 dB at normal gain (GAIN indicator ON) and 1
to +2dB at low gain (GAIN indicator OFF).
Here are some tips for using the DI's:
• The HPF may, in some cases, be used to produce useful tonal varia-
tions. See the "Front Panel Controls" section for more information.
• If you have an instrument with two pickup outputs available, you may
want to try using the MS mode to obtain interesting image or tonal
variations.
• As some guitarists know, certain instruments produce a desirable tone
when the pickups are terminated with a specific resistance/imped-
ance value. While the input impedance of the P2analog is quite high
(2. megohms), we've provided the capability to modify the input
impedance for a specific application. Since this modification requires
opening the product enclosure, it should only be performed by quali-
fied technical personnel. Contact TRUE Systems Technical Support for
more information.
Use only ¼" unbalanced (tip/sleeve) plugs to connect to the DI.
NOTE: DO NOT use TRS plugs for these inputs as the DI will not function
correctly.

noise. In general, the 40Hz setting is appropriate for musical sources and
the 80Hz setting is appropriate for voice. Note that use of the HPF will
most likely not eliminate the need for a pop screen for close mic'd vo-
cals.
