Putting the receiver into operation

Mounting and connecting remote antennas

Use a remote antenna (available as accessories) when the receiver position is not the best antenna position for optimum reception.

￿ Connect the remote antennas to the BNC sockets Oand Rat the rear of the receiver using a low-attenuation 50-Ωcoaxial cable.

Note:

Ready-made antenna cables from Sennheiser are available as accessories with length of 1 m, 5 m and 10 m (see “Accessories/spare parts” on page 43).

￿If you connect active antennas (e.g. A 3700, AD 3700) or antenna boosters (e.g. AB 3700), switch the DC supply voltage for external

active antennas and antenna boosters on (see page 30) so that the LEDs N and S light up; if you do not connect active antennas or

antenna boosters, switch the booster supply voltage off so that the LEDs N and S do not light up.

Note:

If the booster supply voltage is switched on (see page 30), it remains switched on even when the receiver is switched off.

￿Position antennas in the same room in which the transmission takes place! Maintain a minimum distance of 1 m between antennas and a minimum distance of 50 cm between antennas and metal objects (including reinforced concrete walls)!

Daisy chaining receivers

The receivers feature an integrated antenna splitter so that up to eight receivers can be daisy chained using the supplied short antenna daisy chain cables. The label V indicates the daisy chained frequency range.

￿ Connect the two supplied telescopic antennas or two remote antennas (available as accessories) to the BNC sockets O and R at the rear of the first receiver.

￿ Use the supplied 50 Ω antenna cables to daisy chain the receivers as shown in the diagram on the left.

Note:

The antenna signals are also daisy chained when a receiver is switched off. If the booster supply voltage is switched on (see page 28), it remains switched on even when the receiver is switched off.
