Battery Operation; Battery Life; Setting Levels; Dip Switches - Shure M367 User Manual

AC OPERATION
Use the supplied power adapter to connect the M367 to a power
outlet.
M367: 100–120 VAC, 50/60 Hz
M367E: 220–240 VAC, 50/60 Hz
The operating voltage can be switched internally (see Internal
Modifiable Functions).
Appliance inlet is the main disconnect device (to power off
the M367, you must unplug the power supply).

BATTERY OPERATION

Open the battery compartment by grasping the sides of the
compartment, squeezing to release the locks, and pulling the
compartment outward. Insert two 9–volt batteries.
During battery operation, use the BATT CHECK button. Press
and hold to show battery level on the VU meter. Press once to illu-
minate the VU switch for 10 seconds, or set DIP switch 6 for contin-
uous illumination (see DIP Switches).

BATTERY LIFE

With two fresh 9–volt alkaline batteries, the M367 operates for
about eight hours. Some mixer features decrease battery life, as
illustrated in the following table.
NOTE: Momentary use of headphones or meter illumination will
not appreciably affect battery life.
Mixer Operation
No Signal
With +4 dBm continuous output
With six mics at 12 V phantom power
With six mics at 48 V phantom power
With output to headphones
With meter illumination continuously on
*until Power LED begins to flash, allowing approximately 30 minutes to
replace batteries.
CONNECTING M367 OUTPUTS TO TELEPHONE
LINES
Use the XLR outputs at line level to drive dc–biased, "dialed up"
telephone lines. A slight increase in distortion may occur. Use the
M367 limiter with the limiter threshold set to +4 dBm. Modify the
M367 output impedance to 600 Ω for proper fidelity (see Internal
Modifiable Functions). When connecting the M367 to a telephone
line, you must use an FCC–Registered interface adapter between
the mixer and telephone line.

SETTING LEVELS

1.Set the MASTER gain knob to the full off position.
2.Activate the 1 kHz tone oscillator by setting the 1 KHZ TONE
switch to ON. Adjust the MASTER gain until the VU meter needle
indicates "0". Adjust the input levels on the equipment connected
to the M367 outputs accordingly. Deactivate the tone by setting
the 1 KHZ TONE switch to OFF.
3.Adjust the Input gain controls based on the incoming signal lev-
els. The input PEAK LEDs should flicker red only on loud input
peaks.
4.Observe the output on the VU meter and adjust the MASTER gain
to obtain the desired levels. Try to keep the average levels
around "0 VU". The PEAK LED adjacent to the VU meter should
illuminate only on loud output peaks.

DIP SWITCHES

Access the DIP switches by removing the battery compartment
and top cover. Use the following table to set the switches
