INPUT CONNECTIONS
HIGH IMPEDANCE MICROPHONES: The amplifier is
shipped in a configuration for direct connection of high
impedance microphones (50k ohms) to the four MIC input
receptacles of the amplifier. The microphone lead should be
a single-conductor shielded cable under 35 feet long and
terminated in a Cannon XLR-311C connector
(Bogen
Part
No. 85-0124-01) as shown in figure 2.
In the event jumpers on the printed circuit board have
been rearranged and must be returned to the configuration
for direct connection of high impedance microphones,
connect the two jumpers involved as follows: the first
jumper between terminals 11 and 19, and the second
be-
tween 8 and 18. Three jumpers are not involved and are
stored by connecting both ends to an assigned terminal: the
first jumper on terminal 20, the second on 24, and the third
on 25.
BALANCED LOW-IMPEDANCE MICROPHONES:
Low-
impedance accessory transformers are required to permit
the amplifier to accept inputs from microphones rated from
50 to 600 ohms. Before connecting microphone, insert
appropriate plug-in transformers and reset jumpers adjacent
to transformer sockets as described in the Accessories
sec-
tion. Use a two-conductor shielded cable for the
+
micro
phone lead, terminated in a Cannon XLR-311C connector,
as shown in figure 3.
