Instruction manual Digital 9000 System

Preparing the Digital 9000 system for use
40 | Digital 9000
Connecting the receiving antennas/antenna boosters
왘 Use GZL 9000 antenna cables.
A/AB/AD 9000:
왘 Connect the RF out sockets 4 of the antennas/antenna boosters used
to the N-type sockets RF IN A E and RF IN B F of your EM 9046.
AB 9000:
왘 Connect the RF IN socket 6 of the two antenna boosters to one antenna
each.
왘 Use short cables to keep the cable attenuation as low as possible.
Adjusting the receiving antennas/antenna boosters
The EM 9046 receiver controls the preselection of the booster frequency
ranges. No further settings need to be made on the A/AB/AD 9000 anten-
nas/antenna boosters.
You can also use the antennas/antenna boosters with other receivers if
the following conditions are met:
왘 Use a receiver with booster supply voltage (e.g. EM 3732-II).
왘 Use a cable whose length and attenuation match the amplification of
17 dB of the A/AD/AB 9000 antennas and antenna boosters.
왘 Use the “Filter” rotary switch 8 to manually set the booster frequency
range (see table on page 39).
Preparing the SKM 9000 radio microphone
for use
Selecting the accupack/battery pack
For powering the SKM 9000 radio microphone, you can use:
•the BA 60 accupack
•the B60 battery pack for 2 AA size batteries (1.5 V)
Sennheiser GZL 9000 antenna cables are available in lengths of 5 m,
10 m and 20 m.
Charge the BA 60 accupack before using it for the first time (see
page 102).
CAUTION
Damage to the radio microphone and/or the accupack/battery pack!
If you touch the following contacts, they can become dirty or damaged:
• charging and data contacts 1 of the BA 60 accupack
• data contacts 4 of the B 60 battery pack
왘 Do not touch the contacts of the BA 60 accupack nor the contacts of the
B 60 battery pack.
