READING THE LCD SCREEN
The LCD screen displays the status of each function, as follows:
1. Input Level Meter: 3-segment input level meter displays level of incoming signal. Always
check for clipping prior to inserting earphones into ears.
Signal present
Nominal
–6 dB from clip
2. Battery Life Meter: Indicates the amount of voltage left in the battery. If no indicators are
present, change the battery as soon as possible.
HIGH: 6-8 hours of operation.
MEDIUM: 2-6 hours of operation.
LOW: less than 2 hours of operation.
NOTE: Battery life depends on many variables, including battery type (brand),
earphones used, and volume setting.
3. Input Attenuation: Displays the sensitivity of the bodypack's input. Use “0 dB” attenuation
for low levels (–10 dBu), and use “–15 dB” attenuation for higher levels (+4 dBV).
4. MixMode (MIX): Allows the user to receive the monitor mix in either MixMode (MIX ON) or
Stereo (MIX OFF). If the bodypack is receiving only one signal, use MIX ON. See Mono, Ste-
reo and MixMode Control on page 8.
5. High Frequency Equalization (EQ): Adds 6 dB at 10 kHz for improved treble response.
6. Limiter (LIM): Activates and deactivates an internal limiter which provides protection against
loud signals.
WARNING!
Turning the Limiter OFF defeats protection against hazardous sound levels.

MONO, STEREO AND MIXMODE CONTROL
The bodypack provides simple configuration of a monitor mix and enables the user to customize
an individual mix in a multiple mix environment. Three monitoring modes are available - mono,
stereo, and MixMode.
Mono: The bodypack receives one signal from the mixer and sends that signal to both earphones.
For mono signals, use MixMode (MIX ON).
Stereo: The bodypack receives two signals (L and R) from the mixer and sends the signals to the
left and right earphones, respectively. The balance knob adjusts the balance between the left and
right earphones. For stereo signals, use the MIX OFF setting.
MixMode: Allows the performer to easily adjust the monitor mix during the performance. In Mix-
Mode, the bodypack receives two signals, such as a band mix and a vocal mix. The balance knob
adjusts the mix of these two signals. The mixed signal is sent to both the left and right earphones.
For example, if the band is overpowering the vocals in the mix, the vocal levels can be increased
and the band mix level decreased by simply adjusting the balance knob.
