1. MIPRO ACT receivers have an advanced computer network-interfaced controlling

system.

2. Wiring Instructions

!

The network interface of ACT-717/727/747、ACT-717B/727B/747B receivers is

the ''REMOTE'' connector that can be linked to a computer by a MIPRO-DVU or

MIPRO-DVJ hardware device. By using a RS-232 or USB connector, you can link

to a computer through the RS-232 COM PORT or USB PORT. (See diagram

below)

!

Plug one side of the provided cable (w/ RJ-11 connectors) to the REMOTE OUT

socket on the rear of the receiver and the other end of the phone cable to the

REMOTE IN socket on the rear of the second receiver. Repeat this connection

for each receiver in the system as per the illustration. Finally, connect the

REMOTE IN socket on the rear of the first receiver to the MIPRO-DVU or

MIPRO-DVJ.

!

This system can link, monitor and control up to 64 receiver channels

simultaneously.

!

The connecting cable to the computer can be up to 300 meters (330 yards) in

length; however, signal stability decreases the longer the cable distance.

Therefore, the cable length is recommended not to exceed 100m (110 yards) to

maintain the highest quality as well as a high speed of transmission.

True Diversity Receivers

True Diversity Receivers

1.

Since the installation of the antenna influences the operating efficiency of the

receiver, the most important rule is to minimize the distance as much as possible

between the receiving antenna and the microphone for the best reception and

performance.

2.

Use MIPRO supplied antennas to ensure proper receiver sensitivity.

3.

A built-in worldwide approved switching power supply assures stable performance

in the range of 100~240V AC power input.

4.

Please note the main disconnected device is the AC Inlet.

5.

The antenna socket provides an 8V DC biased output. Therefore, shorting on the

antenna socket should be avoided. Temporary shorting on the antenna socket will

not affect system performance; however, continuous shorting on the antenna

socket will cause permanent system damage.

6.

If extended reception distance is needed, installing a MIPRO directional antenna kit

(AT-90W) will increase the reception distance.

7.

Proper antenna distribution is vital to achieving ideal performance from multiple

wireless systems operating in the same environment. To greatly reduce antenna

clutter in multi-system installations, a MIPRO AD-707/AD-707a UHF antenna

divider system is recommended. Each AD-707/AD-707a supports up to four UHF

diversity receivers to operate from a single pair of antennas. When combined with

an AT-70A omnidirectional extension antenna and an AT-70B antenna booster or

an AT-90W directional antenna, the AD-707/AD-707a antenna divider provides

optimal signal reception with minimal dropouts or interference.

8.

Preset non-interfering channels within the same channel group are recommended

to ensure optimum performance from multiple wireless systems installed in the

same venue. Use of preset non-interfering channels from different channel

groups may cause interference, thus is not recommended.
