3 Setting Up

• Prior to setting up the receiver, check that the AC mains voltage stated on your power supply is identical
to the AC mains voltage available where you will use your system. Using the power supply with a differ-
ent AC voltage may cause damage to the unit.
• In the the following sections, flashing characters are identified by angle symbols ">" and "<". All numerical values
shown are examples of possible settings.
Reflections off metal parts, walls, ceilings, etc. or the shadow effects of musicians and other people may weaken or can-
cel the direct transmitter signal.
For best results, place the receiver or remote antennas as follows:
1. Place the receiver/antennas near the performance area (stage). Make sure, though, that the transmitter will never
get any closer to the receiver than 10 ft (3 m). Optimum separation is 16 ft. (5 m).
2. Check that you can see the receiver from where you will be using the transmitter. Shadow effects caused by peo-
ple or objects may disrupt the radio link.
3. Place the receiver at least 5 ft. (1.5 m) away from any big metal objects, walls, scaffolding, ceilings, etc.
• You can either use the receiver freestanding or mount it in a 19" rack using the supplied rack mounting kit.
1. Unscrew the four rubber feet (1) from the receiver bottom panel.
2. Unscrew the two fixing screws (2) from each side panel.
3. Use the fixing screws (2) to screw the short bracket (3) to one side panel and the long bracket (4) to the other side
panel. The brackets are contained in the supplied rack mounting kit.
4. Install the receiver in your rack.
1. Unscrew the four rubber feet (1) from each receiver's bottom panel and remove the screws (5) from the rubber feet
(1).
2. Unscrew the two fixing screws (2) from the right-hand side panel of one receiver and from the left-hand side panel
of the other receiver.
3. Remove the plastic covers (3) from the side panels with the fixing screws (2) still on.
4. Insert one connecting strip (4) into each free slot in the side panel of the first receiver, making sure to align the hole
in each connecting strip (4) with the appropriate threaded hole in the receiver bottom panel.
5. Fix the three connecting strips (4) on the first receiver using three of the screws (5) you removed from the rubber feet.
6. To join the two receivers, slide the connecting strips (4) on the first receiver through the free slots in the side panel
of the second receiver. Make sure to align the hole in each connecting strip (4) with the appropriate threaded hole
in the bottom panel of the second receiver.
7. Fix the connecting strips (4) on the second receiver using the three screws (5) you removed from the rubber feet.
8. Screw a short bracket (6) to the outer side panel of each receiver using for each bracket two of the screws (2) you
removed from the receiver side panels.
9. Install the receivers in your rack.
• Be sure to keep the remaining screws (5) for later use.
• Connect the audio output to the desired input:
- BALANCED socket (8) - XLR cable - microphone input: set output level switch (10) to "-30 dB".
- BALANCED socket (8) - XLR cable - line input: set output level switch (10) to "0 dB" or "+6 dB".
- UNBALANCED jack (9) - 1/4" jack cable - unbalanced 1/4" microphone or line input jack.
1. Check that the AC mains voltage stated on your power supply is identical to the AC mains voltage avail-
able where you will use your system. Using the power supply with a different AC voltage may cause dam-
age to the unit.
2. Plug the feeder cable (1) on your power supply into the DC ONLY socket (2) on the receiver rear panel and screw
down the DC connector (3).
3. Plug the power cable on the power supply into a convenient power outlet.
1. Press the front panel ON/OFF switch to switch power to the receiver ON.
The display will indicate the currently active frequency.
If power to the transmitter is OFF or the RF level at the antennas is zero for some other reason (e.g., shadow ef-
fects), the "MUTE" label will appear on the display and the audio output will be muted.
If the antennas receive RF signal, the bargraph meters below "A" and "B" indicate the field strength of the signal
received by the active antenna.
The bargraph below "AUDIO" indicates the audio level. "CLIP" illuminates to indicate audio signal clipping.
2. After approximately 5 seconds, the display will change to the last active status screen (before powering down) and
the "LOCK" label. The receiver is now in LOCK mode.
3. To power down, press and hold ON/OFF until the display goes dark.
