MIPRO ACT-51 Single-Channel Diversity Receiver - Manual (Page 6)

1. Antenna Installation: Install 2 separate antennas on the antenna sockets ,
on the rear panel. Illustrated in Figure 1.
2. Connecting the power supply: Connect the AC/DC adapter cable to the 12V DC
Input Jack illustrated in Figure 1. Next plug the adapter unit into an appropriate
AC outlet with caution to the correct voltage and rating, as shown in Figure 1.
3. Audio Output Connection:

! Level Switch , Setting Position: When connecting from receiver's
balanced output to the “LINE-IN” jack of a mixer or amplifier or “Electric
Guitar”, switch the Level Switch , to “+10dB” position. Low sensitivity may
occur if switch to the wrong level position. When connecting from receiver's
balanced output to the “MIC-IN” jack of a mixer or amplifier; switch the Level
Switch , to “0dB” position. Overload distortion may occur if switch to the
wrong level position. When using electric guitar, don't use “0dB” or “-6dB”
position as it may have generated insufficient level. There are lots of amplifiers
for Karaoke machine in today's market; however, gain of amplifier's “MIC IN” is
not unified. Therefore, if distortion is encountered, please switch the Level
Switch , to “-6dB” position.
! Unbalanced Output: Using audio output cable attached with “PHONE PLUG”
type, connect one end from the unbalanced output jack , of the receiver,
and the other end to the “LINE-IN” input jack of the amplifier, as shown in
Figure 1.
! 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 2.)

RECEIVER OPERATING TIPS
! Prior to powering on the receiver, ensure all transmitters are turned off and the
mixer's volume control is set to a minimized setting.
! Normally, the RF meter level glows when a transmitter is powered on to indicate
the receiver is ready for operation. Once an audio signal is received from the
transmitter, the AF (audio) meter level glows based on signal strength. If the meter
or indicator does not glow or there is no audio output, the system may not be set
up properly. Re-check that the transmitter is turned on and the receiver and
transmitter are on the same frequency (if not, the transmitter will need to be reset
via the ACT function).
! The microphone output level needs to be adjusted at the amplifier or mixer. There
is no need to adjust output levels at the receiver itself.
! The antenna inputs provide 8-volt DC biased and are designed to work with MIPRO
antenna boosters. If the connecting cable is longer than 10 meters (approx. 30'), it
is advisable to install an antenna booster to ensure optimal reception.
! Antenna dividers and receivers must be from the same frequency band.
