MixMode
Some performers need to hear more of their own voice or instrument, while others
want to hear more of the band. With MixMode, the performer creates their own mix
using the balance control (▼▲ buttons) on the bodypack.
To use MixMode, send a solo mix of the performer to the CH. 1 IN input on the
transmitter, and send a band mix to the CH. 2 IN input.
Set the performer's bodypack for MixMode. The bodypack combines the two signals
and sends them to both earphones, while the balance control on the bodypack ad-
justs the relative levels for each.
LOOP Applications
Use LOOP OUT L (left) and R (right) outputs to send a copy of the audio signal going
into the transmitter to other devices. Following are a few of the many applications for
these outputs.
Note: The input level control and the input pad do not affect the LOOP OUT signals.
MixMode for Multiple Systems
Configure each system for MixMode. From the mixing console, send a mix of the
whole band to input 2 of the first transmitter. Connect the LOOP OUT R output to the
CH. 2 IN input of the next transmitter. Continue the chain with all the transmitters.
Next, create solo mixes for each performer. Send each mix to input 1 of the transmit-
ter for that performer.
Floor Monitors
Send the audio from the LOOP outputs to onstage loudspeakers. The bodypack and
the onstage monitors receive the same audio signals.
Note: The LOOP audio outputs will not drive passive loudpeakers, and must be sent
to a power amplifier or an active loudspeaker.
Recording Devices
To record a performance, connect the LOOP outputs to the inputs of a recording
device.
Point-to-Point Wireless Audio
Use PTP mode to allow a P9T to transmit to a UHF-R receiver. This allows a transmitter
and receiver setup where both units are racked and powered by AC.

Squelch
Squelch mutes audio output from the bodypack when the RF signal become noisy.
While squelch is activated, the blue LED on the bodypack turns off.
For most installations, squelch does not need adjustment, and it keeps the performer
from hearing hiss or noise bursts if the RF signal becomes compromised. However,
in congested RF environments or in close proximity to sources of RF interference
(such as large LED video panels), the squelch may need to be lowered to prevent
excessive audio dropouts. With lower squelch settings, the performer may hear more
noise or hiss, but will experience fewer audio dropouts.
Important: Before lowering squelch, first try to eliminate the problem by finding
the best set of frequencies for your installation and removing potential sources of
interference.
Caution: Turning off or lowering the squelch setting can increase the noise level and
cause discomfort to the performer:
• Do not lower the squelch setting unless absolutely necessary.
• Turn earphone volume to the lowest setting before adjusting squelch.
• Do not change the squelch setting during a performance.
• Turn up the transmitter level setting to make noise or hiss less noticeable.
Squelch Settings
Default factory setting.
HIGH (NORMAL)
Moderately decreases the signal-to-noise ratio required
MID
to squelch the receiver.
Greatly decreases the noise squelch threshold.
LOW
Turns off noise squelch leaving only pilot squelch on.
PILOT ONLY*
Turns off noise and pilot tone squelch. (Sometimes
NO SQUELCH*
used as a debugging tool by monitor engineers or RF
coordinators to "listen" to the RF environment.)
