TG 1000 – General Instructions for Transmitters
36
5. General Instructions for all Transmitters
• Check the transmitter battery and replace or recharge it if
necessary. Use fresh alkaline batteries only or recharge the
rechargeable batteries.
• Switch off the transmitter before changing the batteries.
• If the transmitter is not being used for weeks or months, please
remove the batteries. Batteries can leak when not being used
for a long time and corrode the conductor strips and
components. Repair is not then possible. In this case all warranty
claims are null and void. The description “leak proof” on
batteries is no guarantee that they will not run out.
• From time to time the battery contacts should be cleaned with
a soft cloth moistened with spirits or alcohol.
• Do not throw used batteries into the domestic rubbish, but hand
them in to local collection points.
• For charging rechargeable batteries use standard battery
chargers.
6. Comments on the Audio Level
In the development of TG 1000 it was the objective to create a
system that transmits audio as accurately as possible, that has a clear
level and is as simple as possible to handle.
In order to cover all relevant practical applications with a wide
dynamic range, there are several ways to adjust the audio levels.
Level settings on the transmitter
The TG 1000 system does without the possibility of setting the level
on the transmitters, except the sensitivity switch on the beltpack
transmitter. In return, the analogue-digital conversion, and the
CODEC used with a very high dynamic range are performed. If
required or desired, this concept makes it possible to comfortably
adjust the volume on the receiver without having to synchronise the
transmitter or to make new settings.
Gain switch of the beltpack transmitter:
This switch allows setting a passive attenuation of -12dB. This is
required if sources with an extremely high signal level (e.g. electric
guitars or basses with active pick-ups) are to be connected.
For electret microphones the setting of 0 dB must be used. Should
distortions still occur at very loud signals, the use of microphones
with a lower sensitivity is required, as in this case, the distortion
arises in the microphone itself. The output level of the electret
microphone can not be higher than the supply voltage, which is
provided by the beltpack transmitter, and this level can smoothly be
processed even in the 0 dB position. The -12dB attenuation would
indeed reduce the level, but not prevent the distortion.
Level settings on the receiver
The output volume can be set between 0 and +42 dB for the hand-
held transmitter (menu item “Handheld Gain”) and beltpack trans-
mitter (menu item “Beltpack Gain”) on the receiver front via the
rotary switch.
“Handheld Gain” adjustable range: 0 to +42 dB
“Beltpack Gain” adjustable range: Instrument Active 0dB
Instrument Passive 0dB
Mic 0 to +42 dB
Amplification by the entire system
If the “Instrument passive” function is selected in the “Beltpack
Gain” menu item and the passive pre-attenuation in the beltpack
transmitter is not used, the output level exactly corresponds to the
input level.
With active instruments you should use the passive pre-attenuation
inside the beltpack transmitter.
If the “Instrument Active” function is selected in the “Beltpack
Gain” menu item, a 0 dB structure is produced again.
