NOTE: When M-S is selected, GAIN and polarity (180
) are set to normal on both
Channel 1 and Channel 2. The GAIN selectors for both channels are “locked”
together so that pressing either one causes a similar gain range setting in both
channels.
8 The Stereo Phase Correlation display selector (ON/OFF) determines whether the
LED display is illuminated or not. In some circumstances the display can be very
active or distracting. This selector allows you to simply de-activate the display. See
the section “Stereo Phase Correlation Display” for more information.
Direct Inputs
The Direct Inputs (DI’
s) are used for connection of electric instrument pickups or
unbalanced sources such as synthesizers. The DI’
s we’
ve designed for the
P2
analog
match (or exceed) the sonic performance of acclaimed, dedicated DI products. They
provide excellent articulation and control for electric/acoustic bass, detail and
smoothness for stringed instruments and keyboards. Simply plug the instrument cable
into the front panel DI-1 or DI-2 connector. When an instrument is connected to the DI
input, it overrides the microphone connection. Here are some tips for using the DI’
s:
The HPF may, in some cases, be used to produce useful tonal variations. 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 M-S 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/impedance value. While the input
impedance of the
P2
analog
is quite high (2.5 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
qualified technical personnel. Contact
TRUE Systems Technical Support for more
information.
Use only ¼” unbalanced (tip/sleeve) plugs to connect to the DI. See the “Front Panel
Controls” section for more information.
More About M-S Decoding:
M-S (Mid-Side) decoding is a particularly creative feature of the
P2
analog
. While the
M-S microphone technique has been around for many years, the opportunity to use it is
frequently limited by the need for specialty microphones and/or decoders.
What is M-S?
It is a stereo microphone placement technique
that uses a center, forward-facing omni or
cardioid mic (Mid) and a side-facing figure 8 mic
(Side). The signals from these two mics are
passed through matrix circuitry that combines
them in particular phase and level relationships to
produce a stereo L and R output.
