2. INSTALLATION OF THE RECEIVER
(Fig?!)
IA Install two antennas perpendicularly and l'ully extended to the antenna input connectors
(2008400) at the rear panel ofthe receiver, as shown in Fig 3
2. Power Output Connection:
(a) Connect the ACfDC adapter cable to DC I2V INPUT JACK (25). then plug the adapter
unit into an appropriate AC outlet with caution to the correct voltage under both AC
outlet and adapter marked, as shown in fig. 4.
(b) With the appropriate AC power cable connects fi'om AC Input Jack (29) to an AC
outlet under the marked voltage 85465 V, as shown in Fig i

3 Audio Output Connection:
(3) Unbalanced Level Switch (24) Setting Position: When inputs the unbalanced output ofa
receiver into “Line-in" input jack ot'a mixer or amplifier or "Electric Guitar", switch the
Level Switch (24) to the right “HIGH" position. Low sensitivity may occur if switch to
the wrong position When input the unbalanced output ofa receiver into the "MICJN"
input jack of a mixer or amplifier; switch the Level Switch (24) to the lefi “LOW"
position. Overload distortion may occur if switch to the wrong position. When using
electric guitar, don’t use "LOW" position as it may have generated insufficient level.
(b) Unbalanced Output. Using audio output cable attached with "PHONE PLUG" type,
connect one end from the unbalance-mixed output jack (23) or the unbalanced Output
jack (22) of" the receiver, and the other end to the “LINE-IN” input jack of the amplifier.

(c) Balanced Output: Using audio output cables attached with “XLR' or ”Cannon" type,
connect one end (tom the balanced output jacks (2 l)&(27) of the receiver, and the other
end to the “MIC IN“ input jack of the mixer or amplifier, as shown in Fig. 3. (The
characteristic of the 3-pin connector is as shown in Fig 6)
(d) Guitar Output: Using audio output cable attached with ”PHONE PLUG" type, plug one
end from the unbalance-mixed outputjack (23) or the unbalanced output jack (22) ofa
receiver, imd the other end to the inputjack ofa guitar amplifier. Switch the Level
Switch (24) to “HIGH” position.

4. Make sure that the system performs correctly by placing the system away from noise
sources. Place the receiver at least 1 meter above the ground and away from noise
sources. Place the microphone at least 1 meter away fi-orn the receiving antenna, as shown
in Fig. 7.
5. The provided two rackmount brackets can be installed and mount into an EIA standard
rackmount case, as shown in Fig. 8. As an accessory, you may purchase from MIPRO a
front antenna rackmount brackets (FBJO), which can bc mounted easily as front antenna.

3. RECEIVER OPERATING PROCEDURES
I. Turn volume controls of the receiver and mixer in use to a minimum setting before tum on
the microphones or transmitters Met switches on the receiver. the power switch (1) red
indicator illuminates to denote normal power status
(Fist?)
2. IfSIGNAL LED indicators (4)(l l) of the receiver light on before switching on the
microphone or transmitter, it indicates the receiver is receiving interference signals. The
more LEDs light on the more severity of interference. This system has Pitlotqne and
NoiseLoclt dual-squelch features and no noise output will occur If multiple clumncls are
used and both SIGNAL and AUDIO LEDs firm and interference noise appear, simply

adjust the Squelch controls (26ji28) clockwise until AUDIO signal indicators to
extinguish (Fig 9) However. by adjusting the squelch controls. it affects the sensittvrty
let cl ot‘the receiver. therefore. shorten the operating distance and decreases the stability.
Adjust the Channel Sulcctor (5)( 12) to a non-interference channel ifadjusting the Squelch
control is not able to eliminate the interference
. Under normal circumstances. the SIGNAL indicator lights up when a microphone or
transmitter is turned on near the receiver to indicate the receiver is ready for normal
operation Once sounds to tilt: microphone and the AUDIO LED indicators (3)( 10) Will
glow according to the strength of sound level It“ nu LED glows or no sound outputs. the
system is not function properly. thus it must be checked
4 Receiver and Amplifier Volume Adjustment:
to) Single-channel Unbalanced Audio Output Switch the level switch (24) on the receiver
rear panel to the lelt “LOW" position. then adjusts the volume control (2) to 12 o'clock
positron (Middle posi on of the knob) Lastly. adjusts volume control of the amplifier
or mixer to an appropriate sound level The volume control (2) is used for fine
adjusting the microphone sensitivity. When knob turns to 12 o‘clock position. the
output level ol‘the wircicss microphone sensitivity is the same as the normal dynamic
microphone Once appropriate ul'thc receiver output level is fine adjusted, only to
adjust the mixer or amplifier volume control if the sound level needs to increase or
decrease Don't adjust the volume control (2) again.
(h) Dual-channel Unbalance-mtxed Audio Output. Same adjustment as the single-channel
volume control [2M9] because the output jack (23) is a mixed audio signal Each
volume control (ZH’JJ adjusts the loudness ofeaclt channel Each channel volume
control is independently controlled and rto cross-talk will occur
(c) I or 2 channel Balanced Output' According to the unbalanced audio output adjusting
method is acceptable The balanced output is irrelevant to the level switch (24).
(d) In order to obtain same sensitivity level for both wired microphones in use at the same
amplifier or miscr With audio cables connect both Wired microphone and tourism
output to each "MIC It ' input jack orthc amplifier rtr mixer Adjust both volume
controls ol'tlte amplifier or mixer to the same desired level. then properly tine adjust the
receiver volume control (2) to match the same sensitivity as the wired microphone.
(e) If the receiver output level is adjusted excessively, it will cause the saturation distortion
ot‘tltc mixer or amplifier when the microphone is loud Conversely. SIN ratio will
worsen it'thc rcccivcr volume control (2) is adjusted too low.
5 The battery charging system incorporates a proprietary built-in intelligent battery charger
system on the receiver. lt accommodates either 1 or 2 PCs 7 2 Volts rechargeable
batteries per charge The indicators (17m 8) red light indicate chargng while green light
indicate the batteries are fully charged and it cuts of!" charging current automatically to
avoid possible overcharged.
