SQELCH SqELCH

Adjusting the squelch threshold (receivers only)

The Sennheiser evolution wireless series ew 500 receivers are equipped with an adjustable squelch which eliminates annoying noise when the transmitters are switched off. It also suppresses sudden noise when a transmitter leaves the reception area and there is no longer sufficient transmitter power received by the receiver.

￿Select the “SQELCH” menu by pressing the SET button until “SQELCH” appears on the display; after a short pause the current squelch setting is displayed.

￿	With the / buttons you can now select a different setting. The
	squelch can be switched off (0 dB) or adjusted in 5-dB steps from
	5 dB to 40 dB. Selecting a smaller value reduces the squelch threshold,
	selecting a higher value increases the squelch threshold. The new
	setting starts flashing on the display. Set the squelch threshold – with
	the transmitter switched off – to the lowest possible value that
	suppresses hissing noise. If the squelch threshold is set too high, the
	transmission range will be reduced.
	Note:
	With the transmitter switched off and the squelch threshold set to
	“0 dB”, hissing noise will occur. With the EM 500 receiver, the “PEAK”
	warning of AF level bargraph will light up.

￿Press the SET button to return to the top menu level. The display then switches back to the standard display.

Att	Selecting the sensitivity range (SKP 500 only)
	Condenser microphones require a different sensitivity range than dynamic
	microphones. With the SKP 500 plug-on transmitter, you can switch the
	sensitivity range by 20 dB.
	￿	Select the “Att” menu by pressing the SET button until “Att” appears
		on the display; after a short pause the current setting – i.e. “Att off” or
		“Att on” – is displayed.
	￿	With the / buttons you can now switch between two different
		sensitivity ranges.
		: Sensitivity range 1 for dynamic microphones
		– “Att off” flashes on the display
		: Sensitivity range 2 for condenser microphones
		– “Att on” flashes on the display
	￿	Press the SET button to return to the top menu level. The display
		then switches back to the standard display.

Note:

For recording of quieter signals (e.g. wildlife) with a condenser microphone, you may find it better to set the sensitivity to “Att off”.
