Putting the receiver into operation

N O P Q R S

Connecting and positioning remote antennas

Use remote antennas when the position of the double receiver is not the best antenna position for optimum reception. Remote antennas are available as accessories.

￿Connect the remote antennas to the BNC sockets Oand Rusing a low- attenuation 50-Ωcoaxial cable.

Ready-made coaxial antenna cables from Sennheiser are available as accessories with length of 1 m, 5 m and 10 m (see “Accessories” on page 45).

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

active antennas and antenna boosters (see page 32) so that the LEDs N and/or S light up;

if you do not connect active antennas or antenna boosters, switch off the booster supply voltage so that the LEDs N and/or S do not light up.

If the booster supply voltage is switched on (see page 32), 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

ANT A

 

ANT B

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 type plate U indicates the daisy chained frequency

 

 

 

range.

 

 

 

￿ Connect the two supplied 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-Ωantenna daisy chain cables to daisy chain the

 

 

 

receivers as shown in the diagram on the left.

 

V

 

The antenna signals are also daisy chained when a receiver is

 

 

switched off. If the booster supply voltage is switched on (see

 

 

 

 

 

 

page 32), it remains switched on even when the receiver is

 

 

 

switched off.
