RF Wireless Systems 3000 Series Receivers

Mounting the telescopic antennas

The EM 3031 and EM 3032 receivers are fitted with an adjustable RF squelch, which mutes the audio output when the antenna voltage drops below the chosen thresh- old. The squelch can be adjusted between 0 and approx. 100 µV. When the squelch has been triggered, the “MUTE” warning will light up on the receiver display. The receivers are additionally equipped with an AMF advanced muting function. This muting function is triggered when the RF signal suddenly drops by approx. 50 dB. The receiver will then be muted for about 3 seconds to avoid the annoying crackling noise which is caused when a transmitter is switched off.

The EM 3031 and EM 3032 receivers have a headphone output for monitoring the incoming audio signal; the monitoring signal is mono. Sennheiser’s closed HD 25 headphones are an ideal choice for monitoring purposes. In order to enable monitor- ing even in unfavourable conditions (e.g. low AF signal level from the transmitter) and with high ambient noise (on the stage, for example), the signal from the headphone output is up to 30 dB louder than the LINE output signal. However, this may lead to distortion if the level of the incoming signal is quite high and if the volume control is turned up. In this case, turn back the volume until the distortion disappears. If the sound remains distorted, the transmitter itself is overmodulated.

The Sennheiser transmitter range includes many models which transmit battery status information. The EM 3031 and EM 3032 receivers are able to receive this status information. They display the remaining battery or accupack capacity of the transmitter in %. When the battery is going flat and the remaining capacity lasts for only 20 to 30 minutes of operation, the “LOW BATT” warning on the display starts flashing. You should immediately replace the transmitter battery.
