3 General
8 Infrared emitter: Transmits frequency data from the receiver to the handheld or body-
pack transmitter. It also transmits the audio gain setting selected on the receiver to the
handheld transmitter.
The infrared emitter has a very narrow radiation angle (approx. 10°) and a maximum
range of 8 inches (20 cm) to make sure only one transmitter will be tuned to the same
frequency.
9 Output level control: This retractable rotary control attenuates the level of the balanced
audio output continuously by 0 to 30 dB.
Rear Panel
10 DC IN: Locking DC input for connecting the included power supply.
11 ANTENNA A/B: BNC sockets for connecting the two supplied UHF antennas (11a) or
optional remote antennas.
12 BALANCED: Balanced 3-pin XLR audio output for connecting to, e.g., a microphone
input on a mixing console.
13 UNBALANCED: Unbalanced 1/4" TS audio output jack for connecting to, e.g., a guitar
amplifier.
14 Output level switch: Slide switch for matching the BALANCED output level to the input
gain of the equipment connected to the receiver. The switch has two positions, 0 and
-30 dB. The UNBALANCED output level is not adjustable.
15 Type plate indicating available carrier frequency ranges and approval information.
16 Microphone element: The handheld transmitter uses a permanently attached D 5 or
C 5 microphone element (see packaging).
17 Infrared sensor: Receives the infrared signal emitted by the receiver for automatically
setting the transmitter's carrier frequency and audio input gain.
18 LCD display: Indicates the selected frequency in MHz or as a Preset subchannel, cur-
rent mode, transmitter audio gain setting, error messages, as well as the available bat-
tery capacity in 1-hour increments for dry and 2-hour increments for rechargeable
batteries.
19 ON-MUTE/PRG-OFF: This slide switch provides three positions:
ON: The microphone output signal is fed to the transmitter for transmission to the re-
ceiver (normal mode). The status LED (20) is lit green.
MUTE/PRG: The audio signal is muted.
Sliding the switch to "MUTE/PRG" places the transmitter in programming mode.
To switch the audio signal back on, slide the switch to "ON".
OFF: Power to the transmitter is off. The status LED (20) is dark.
20 Status LED: This bicolor LED indicates the following conditions:
Green: The battery will last for more than one hour, the transmitter is in normal mode.
Red: The battery will be dead in less than one hour and/or the the audio signal is muted.
Flashing red: Error message in the display.
Off: Power to the transmitter is off or the transmitter is in programming mode.
21 Battery compartment for the supplied AA size 1.5 V dry battery or a commercial
1.2 V, ≥2100 mAh NiMH AA size rechargeable battery.22 Charging contacts: The
recessed charging contacts allow you to charge a rechargeable battery on the optional
CU 400 charger without having to remove the battery from the transmitter.
23 Frequency sticker: Sticker attached to the transmitter shaft, indicating the available
carrier frequency range and approval data.
