DHTRQUAD System
DHTRQUAD System
DHTRQUAD System
Thank you for purchasing the DHTRQUAD wireless system. For users who need an
advanced UHF wireless system, the DHTRQUAD provides an excellent solution.
With 120 selectable channels, the DHTRQUAD is perfect for applications such as
live shows, broadcast, meetings, & musical instruments. Touch buttons and liquid
crystal displays allow for a quick and simple system setup. The "User Guide"and"
Quick Setting Guide" included in your system will provide all the details you need to
operate the system efficiently.
Frequency Band
Most countries closely regulate the radio frequencies used in the transmission of
wireless information. These regulations state which devises can use which
frequencies, and help to limit the amount of RF (radio frequency) interference in all
wireless communications. The DHTRQUAD offers 120 selectable channels within
either the 584-607MHz (Code D) or 655-679MHz (Code L) frequency ranges.
To facilitate system setup and protect against RF interference, each system comes
with multiple predefined frequency groups and channels. When using a single
receiver/transmitter, the operating frequency will generally not have to be changed.
In an installation with multiple receivers/transmitters, each set must operate on a
separate channel from the others. The group and channel system provides an
optimum frequency spread when using multiple receiver/transmitter systems.

Transmitting frequency automatic setup:
Place the Transmitter “IR” window to face the Receiver “IR” window.
Then press the “ASC” button on the desired Receiver. The Transmitter
will automatically match the Receiver frequency.
Attention: The distance between the Receiver and Transmitter
IR windows should be less than 0.5m during the ASC IR setup. When

Setting up multiple receivers
Setting up multiple receivers
1) Power on any pre-existing wireless systems and transmitters except the first DHT system.
2) Power on the first DHT Receiver.
3) The Control and set buttons are on the front of the receiver.
4) Press the set button until the group number flashes on the LCD screen
5) Press the up/down buttons to select group 1.
6Press the set button twice to get to the scan mode.
7) Press the up or down button. The unit will now go into scan mode. You will probably see the RF
meters light up if the scan sees other transmitters.
8) When it stops scanning, it will stop on the clearest frequency, and will be flashing the frequency
on the LCD screen.
9) Press the set button and it will set itself to that frequency. Do not wait to press the set button as
the DHT Receiver will revert back to the original frequency, and the process will need to be restarted
10) If the unit cannot find a good frequency within group 1, start the process again scanning
group 2, if that is also not clear try group 3, and so on till you get a good frequency.
When the DHT Receiver has been set to a clear frequency, use the ASC feature to sync the
receiver frequency to the transmitter.
11) Turn the transmitter on, aim the red infrared window on the transmitter towards the one on
the receiver and press the ASC button on the front of the receiver. The transmitter will sync to
the receivers frequency.
If you have more DHT systems to tune follow the same procedure on each one, always leaving
the previous system transmitter on.

The 3 position Squelch Adjustment helps to prevent extraneous RF from being picked up and turned
into audio when the transmitter is off. The higher level will reduce the useable distance of the transmitter
from the receiver. Use the lowest setting to keep the receiver quiet when the transmitter is off.

Issue Indicator Status Solution
Troubleshooting
Transmitter LCD off. Turn on transmitter.
Make sure the batteries are installed
correctly.
Receiver LCD off. Make sure AC adapter is securely
plugged into electrical outlet and into
DC input connector on rear panel of
receiver.
Receiver indicates RF. Increase receiver volume.
Make sure Gain adjustment switch on
the transmitter is set correctly (applies
only to MBP76 Bodypack.)
Receiver indicates No RF,
Transmitter LCD is on.
Make sure Transmitter and Receiver
are set to the same frequency.
Make sure Transmitter is in range of
Receiver.
Make sure no large metal objects are
near Transmitter or Receiver.
The battery power indicator
light on LCD flashes.
Change the batteries in transmitter.
Distortion or
unwanted noise.
Receiver Indicates RF. Remove nearby sources of RF inter-
ference (CD players, computers,
in-ear monitor systems, etc.)
Distortion level
increases gradually.
Sound level different
from cabled guitar or
microphone, or when
using different guitars.
Adjust Transmitter Gain and Receiver
Volume as necessary.
Transmitter power indicator
light flashing on the LCD.
Replace Transmitter batteries.
Maintain a line of sight between transmitters and antennas.
Avoid placing the receiver near metal surfaces or any digital equipment (CD players, computers, etc).
Keep the receiver away from the wall and at least 1m from the ground.
Cellular telephones and two-way radios can interfere with the operation of wireless systems.
Do not use these devices in close proximity to the wireless systems.
