Putting the receiver into operation

Connecting devices with AES3 digital input

G

H I

The digital balanced XLR-3M audio output G outputs the signals of both receivers in AES3 format.

￿Use a special double-shielded 110 Ω AES3 cable to connect the device with AES3 digital input to the digital balanced XLR-3M audio output G. This prevents that the digital data transmission interferes with RF reception.

A ready-made AES3 cable from Sennheiser is available as an accessory with a length of 10 m (see “Accessories” on page 45).

￿Via the “Clock” menu, select the desired sampling rate (see “Selecting the sampling rate for digitalization” on page 34).

Connecting an external word clock generator

The receiver can digitalize the audio signal and output it via the digital balanced XLR-3M audio output G. The built-in A/D converter supports sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz.

If you want to connect an external word clock generator instead, proceed as follows:

￿Use a shielded 75 Ω coaxial BNC cable to connect the external word clock generator to the BNC socket H.

￿From the “Clock” menu, select “Ext.” (see “Selecting the sampling rate

for digitalization” on page 34).

The display for external word clock synchronization B:

–lights up permanently when the digital audio output of the receiver is synchronized with the external word clock generator,

–flashes when “Ext.” is selected in the “Clock” menu but no external word clock generator is connected,

–flashes when the signal of the external word clock generator is available but has not synchronized the digital audio output of the receiver,

–is off when the receiver’s internal word clock generator is used.

• Both receivers of a twin receiver use the same word clock signal.

•The receiver has a BNC socket for word clock daisy chain output I for supplying the word clock signal to further daisy chained receivers using the supplied BNC word clock daisy chain cable. The word clock signal is also daisy chained when a receiver is switched off.
