    Keep away from obstacles such as walls, floors, power amplifiers and steelwork.

12. Balanced Audio Outputs A/B/C/D Individual, balanced audio outputs via 3 pin XLR for audio channel.

Operation:

• Carefully, connect the antennae and lift into the vertical position ensuring clear line of sight to the transmitter.

• RF Signals may be affected by many factors. Avoid placing the receiver near metallic objects or near other sources of RF transmission including IEM transmitters and WiFi access points. The receivers should be located as close to stage as possible to minimise signal degradation due to large crowds, stage structures or long distances.

• Connect the included power supply to a suitable 240V AC~ 50Hz mains voltage outlet and plug the DC connector into the DC Power Input on the rear panel of the receiver (12-18V DC, 800mA minimum)

• Using the supplied audio cable, connect the MIX OUT on the rear panel of the receiver for all four audio channels to the mixer’s audio line input, alternatively the receiver also features balanced XLR outputs, one for each channel allowing full control of each channel.

• Switch on the power to the receiver, checking the display backlight illuminates

• Open the battery compartment on the transmitter (Beltpack – squeeze the buttons on the side and open the battery door forwards away from the belt clip. Handheld – unscrew the lower portion). Install the appropriate batteries into the transmitter, taking care to observe the orientation and polarity. Only use high quality, alkaline type batteries. Refit the battery compartment cover carefully.

• Switch on the transmitter, when switched on the display on the transmitter will illuminate. If the display does illuminate or glows dimly, the battery will require replacement.

• Follow the IR Sync and Frequency Setup Operation fully to ensure the transmitters are linked correctly to the receiver unit. Failure to follow this fully will prevent the microphone system from operating correctly. Factory presets may not be suitable for use.

• Adjust the volume on the front panel of the receiver for each of the channels to suit the gain structure of the mixer they are to be connected into.

• Channel (Frequency) Setup:
  Press the SW button to access the menu function and select a channel to be configured. As each channel is selected the display will remain illuminated and the other channels will dim. Press the MENU dial to select the GROUP and CHANNEL. The full list of selectable frequencies, groups and channels can be found on page 7 of this manual. Group “U” will allow the user to advanced access to tune the receiver by selecting either 1Mhz or 25Khz frequency steps. This mode may allow selection of frequencies which overlap or cause inter modulation with other receiver channels.

• IR Sync Operation:
  After making changes to the settings on the receiver, the IR Sync operation should be carried out to ensure the settings are replicated into the transmitter to ensure correct operation. Place the transmitter within 0.5m of the receiver with the IR receiver pointed towards the receiver’s IR window ensuring both transmitter and receiver are powered on. Press the ACT button and the receiver will begin IR Sync. When completed the receiver will show “Success” and the transmitter will then change to match the settings on the receiver. The microphone is now ready for use. Each transmitter should be synchronised individually.

• Frequency Scan Mode:
  To allow the user to select a frequency free from interference, the receiver features a frequency scan mode. Firstly, switch on any transmitters from other systems in the vicinity. Ensuring any transmitters are powered on, press the SCAN button to activate the receivers scan function on each of the individual channels one at a time. Once the receiver has completed the scan function and located a frequency suitable for use the display will show “Scan Complete”. Should the receiver be unable to detect a clear frequency, the receiver will show “Scan Fail”. In this instance, either manual selection of frequency may be required or if the local environment is busy with RF transmissions (i.e. if many other radio microphones are in use) then a change of location or equipment may be required.

NOTE:
The DQM 600/800 system is shipped with four handheld transmitters. The receiver in this system features a quad channel receiver allowing four handheld microphones to be used simultaneously, an additional belt pack kit maybe purchased if required to be used in place of the handheld transmitters. Each receiver channel in this system may only be used with one transmitter at any one time. If the user attempts to power on, and use two transmitters on the same receiver frequency the system will malfunction and not operate correctly as one transmitter will cut out the RF Radio signal to the second transmitter.
Available in two frequency ranges, the DQM 800 series is for use in the 823-832Mhz CH65 and 863-865Mhz CH70 band (CH70 is license free in the UK) while the DQM 600 series is for use in the 606-614Mhz CH38 band. To operate microphones in the 823-832Mhz CH65 or 606-614Mhz CH38 band the user must obtain a license from the relevant authorities in the UK before using the product. Outside of the UK, the user must clarify the frequencies with their local government office responsible for radio microphone frequencies.
