INSTALLING THE MD 108
1. Position the tuner the shortest distance from your preamplifier. Avoid putting the unit
where there are extremes in temperature.
2. Remove the AC cord from the pouch on the lid of the carrying case and plug it into the
AC receptacle at the rear of the unit. DO NOT PLUG THE CORD INTO THE WALL
POWER SOURCE AT THIS POINT.
3. Connect the tuner to your preamplifier using a set of cables consistent with the caliber
and type (balanced or unbalanced) of your system. Select the tuner input on your
preamplifier.
Note: Be sure that the preamplifier is set to zero.
4. Connect the FM antenna and/or cable to the A1 (if you only have one antenna) and A2
connector at the rear of the tuner.
5. Plug the tuner’s AC power cord into an AC power source. Be sure to use a continuous
power source so as to allow the stand-by mode feature to function properly. All the
tuner’s amplifiers are muted in stand-by mode.
6. When power is supplied, some of the tuner’s LED devices may be lit, indicating that the
tuner has been activated. It may also be that the tuner’s power is totally off and that none
of the LED devices will be lit. Either condition is normal.
7. If the power is “OFF”, use the power switch to turn the power to “ON”
Note: Each time the tuner is turned “ON”, there is a 15 second delay before the
tuner will operate. A light click will be heard, indicating that the relay has been
activated and the power is available. Also, the LED devices will be lit which
indicates power.
8. Once power has been initialized, the meters will light and the frequency meter should
show a reading between 87.5 and 108.5.
Ø Switch the tuner to Stereo mode
Ø Turn on the Blend switch
Ø Turn off the Mute switch
Ø Turn off the Dim switch
Ø Turn on the BW 3 switch
The tuner is now ready for operation.
Note: When the tuner is turned off, the LED devices for the main selectors will stay on.
UNIT LAYOUT
INPUTS (Located at rear of unit): The MD 108 has two antenna inputs, labeled A1 and
A2. These are controlled by the front panel input selector knob (Knob on left side of front
plate). The inputs D1 and D2 are for future use.
OUTPUTS (Located at the rear of the unit): The MD 108 uses high grade XLR
connectors for balanced output in a fully balanced system. Unbalanced output is handled
through the high quality gold plated WBT RCA connectors. Composite output, used for
monitoring the monophonic component of a signal, normally used by professional studios, is
handled through the composite output jack located on the rear panel.
