AKG Acoustics WMS 400 Rear Panel, Audio Outputs, Bottom Panel HT 400 Handheld Transmitter

2 Description

5RF LEDs: The green OK LED is lit to indicate the receiver is receiving RF signal, the red MUTE LED indicates that no signal is being received.

6A and B diversity LEDs: These two LEDs are lit to indicate which of the two antennas is currently active.

7AF LEDs: Indicate the received audio level:

OK (green): -40 dB to +3 dB

CLIP (red): >3 dB (overload)

8Infrared emitter: Transmits frequency data from the receiver to the handheld or bodypack transmit- ter. 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 inch- es (20 cm) to make sure only one transmitter will be tuned to the same frequency.

9Output level control: This retractable rotary control attenuates the level of the balanced audio output continuously by 0 to 30 dB.

10DC IN: Locking DC input for connecting the included power supply.

11ANTENNA A/B: BNC sockets for connecting the two supplied UHF antennas (11a) or optional remote antennas.

12BALANCED: Balanced 3-pin XLR audio output for connecting to, e.g., a microphone input on a mix- ing console.

13UNBALANCED: Unbalanced 1/4" TS audio output jack for connecting to, e.g., a guitar amplifier.

14Output 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.

15Receiver type plate indicating available carrier frequency ranges and approval information.

16Microphone element: The handheld transmitter uses a permanently attached D 880 or C 900 micro- phone element (see packaging).

17Infrared sensor: Receives the infrared signal emitted by the SR 400 receiver for automatically setting the transmitter's carrier frequency and audio input gain.

18LCD display: Indicates the selected frequency in MHz or as a Preset subchannel, current mode, transmitter audio gain setting, error messages, as well as the available battery capacity in 1-hour increments for dry and 2-hour increments for rechargeable batteries counting down from "7 h".

19ON-MUTE/PRG-OFF:This slide switch provides three positions:

ON: The microphone output signal is fed to the transmitter for transmission to the receiver (normal mode). The status LED (20) is lit green.

MUTE/PRG: The audio signal is muted. The status LED (20) is lit red. Since power and the RF sec- tion remain ON, no unwanted noise will become audible from the sound system when you mute the audio signal.

Sliding the switch from "OFF" to "MUTE/PRG" places the transmitter in programming mode. The status LED (20) will extinguish.

To switch the audio signal back on, slide the switch to "ON". The status LED (20) will change to green.

OFF: Power to the transmitter is off. The status LED (20) is dark.

20Status 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.

21Battery compartment for the supplied AA size 1.5 V dry battery or a commercial 1.2 V, ≥2100 mAh NiMH AA size rechargeable battery.

22Charging 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.

23Frequency sticker: Sticker attached to the transmitter shaft, indicating the available carrier frequen- cy range and approval data.

24Color code for channel identification: If you use the transmitter within a multichannel system, you can remove the black cover, letter and insert one of the supplied paper strips, and replace the cover with the supplied clear-plastic cover.
