1. Antenna Installation: Install 2 separate antennas on the antenna sockets ,
on the rear panel. Illustrated in Figure 1.
2. AC Power Operation: Connect the AC power cable to the AC Input Jack , then
plug the other end into an AC outlet having the correct voltage and rating, as shown
in Figure 1.

Level Switch Setting Position: When connecting from the receiver's
unbalanced ¼” output (ACT-71 only) to the "LINE-IN" jack of a mixer or an
electric guitar amplifier, switch the Level Switch to the “+16dB” position. Low
sensitivity may occur if switched to the wrong level position; therefore, don't use
the “0dB” or “-6dB” positions as they may not deliver a sufficiently high level of
input. When connecting from a receiver's balanced output to the "MIC-IN" jack of
a mixer, switch the Level Switch to the “0dB” position. Overload distortion may
occur if switched to the wrong level position. There are many different amplifiers
for Karaoke machines in today's market; however, the gain of many of these
amplifier's "MIC IN" is not consistent. Therefore, if distortion is encountered,
please switch the Level Switch to the “-6dB” position.
Mixed Output: Balanced output socket (XLR) must connect to the balanced input
socket of the mixer. This output socket generates the mixed output of Ch.1~Ch.4
and the output sensitivity can be adjusted to “+16dB” or “0dB” or “-6dB” by the
level switch on the right side of the socket. (ACT-72/ACT-74)

Electric Guitar Output: Using audio output cable with ¼” “phone plug” type
connectors, plug one end into the unbalanced output jack of a receiver (ACT-71
only), and the other end into the input jack of a guitar amplifier. Switch the Level
Switch to “+16dB” position (the switch will show “+16dB” on the receiver, but
actually puts out “+10dB” on the unbalanced jack).
Unbalanced Output: Using an audio output cable with ¼” “PHONE PLUG” type
connectors, connect one end from the unbalanced output jack of the receiver,
and the other end to the “LINE-IN” input jack of the mixer or guitar amplifier, as
shown in Figure 2. (ACT-71 only)
Balanced Output: Using audio output cables with “XLR” or “Cannon” type
connectors, connect one end to the balanced output jacks of the receiver, and
the other end to the “MIC IN” input jack of the mixer or amplifier, as shown in
Figure 1. (The configuration of the 3-pin connector is as shown in Figure 3)
