SWIVEL ADAPTER
FIGURE 4
Making sure the thumbscrew will clamp on the silver
metal segment of the connector, NOT ON THE BLACK
PLASTIC PART, tighten the thumbscrew.
CAUTION: Tightening the thumbscrew on the plastic
section of the connector could damage the connector
body.
Tilt the adapter to aim the microphone as desired.
To remove the microphone without disturbing the
swivel adapter and cable, reach into the open slot of the
adapter and press the cable-lock button while disen-
gaging the microphone.
BATTERY INSTALLATION
To install batteries, remove the two screws in the bottom
corners of the preamplifier case. Lift off the case cover
exposing the battery compartment. The use of 9-volt alka-
line batteries (NEMA 1604A or equivalent) is highly
recommended. Two batteries are required; always replace
batteries in pairs.
To prevent possible damage due to leakage, remove the
batteries if the unit will not be used for a long period of
time.
INTERCONNECTING CABLE
One 4.6m (15 ft) cable is supplied for connecting the
SM98 Microphone to its preamplifier. To retain access to
the switches located on the preamplifier, it is sometimes
desirable for the units to be located a greater distance
apart. Up to 15m (50 ft) of additional cable can be used
between the SM98 Microphone and preamp with no loss in
response or output.
POWERING THE SM98
The SM98 can be powered by two internal 9-volt alkaline
batteries or by an external simplex supply of 11 to 52 volts
dc.
To use batteries, move the Battery On/Off switch to On.
The green LED will indicate at least 8 hours of battery life
remaining by flashing once when the switch is moved to
On. If the LED does not flash, the batteries should be
replaced. A battery-powered SM98 preamplifier output
can be connected to any balanced-line low-impedance
input.
To use simplex power, connect the preamplifier output
to a balanced-line microphone input supplying 11 to 52
Vdc simplex (phantom) power. The batteries may be left in
place while the unit is externally powered. There will be no
battery drain as long as the simplex voltage exceeds the
battery voltage with the battery switch On, or if the battery
switch is turned off.
