Preparing the receiver for use

Recommendations for optimum reception

To ensure optimum reception even under difficult conditions, we recommend connecting remote antennas and, if necessary, using antenna splitters (see “Accessories and spare parts” on page 49).

When rack-mounting the receiver, you can mount the supplied antennas to the front of the rack by using an antenna front mount kit. When mounting more than one receiver into a rack, you should use remote antennas.

If you want to mount the receiver into a 19” rack:

왘 Read the corresponding chapter on page 13.

If you want to set up the receiver on a flat surface:

왘 Read the next chapter.

Setting up the receiver on a flat surface

CAUTION! Risk of staining of furniture surfaces!

Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining.

왘 Do not place the receiver on delicate surfaces.

Fastening the

stacking elements

The stacking elements are designed to help protect the operating elements from damage or deformation, e.g. if the receiver is dropped. Therefore, fasten the stacking elements, even if you do not want to stack your receivers.

Putting the receiver into operation



To fasten the stacking elements :

왘 Unscrew and remove the two recessed head screws (M4x8) on each

side of the receiver (see left-hand diagram).

왘 Secure the stacking elements  to the sides of the receiver using the

previously removed recessed head screws (see right-hand diagram).

Fitting the

device feet

If you want to stack receivers (see next section), only fit the device feet to the base of the lowermost receiver.

Do not fit the device feet when mounting the receiver into a 19” rack.

왘 Clean the base of the receiver where you want to fix the device feet.

왘 Fit the device feet to the four corners of the receiver as shown.

왘 Place the receiver on a flat, horizontal surface.

Stacking receivers You can stack several receivers on top of each other.

CAUTION! Danger of injury due to toppling receiver stacks!

High receiver stacks can easily topple over.

왘 Place the stack on an absolutely flat surface.

왘 Secure the stack against toppling over.

왘 Fasten the stacking elements as described in the previous section.

왘 Stack the receivers so that the recesses of the stacking elements

completely engage with each other.

Putting the receiver into operation

Connecting the

rod antennas

The supplied rod antennas  can be mounted quickly and easily and are suitable for all applications where – good reception conditions provided – a wireless transmission system is to be used without a large amount of installation work.

왘 Connect the two rod antennas  to the BNC sockets  and  at the

rear of the receiver.

Mounting the receiver into a 19” rack

Do not mount the stacking elements and do not fit the rubber feet when mounting the receiver into a 19” rack.

Putting the receiver into operation

CAUTION! Risks when rack mounting the receiver!

When installing the device in a closed or multi-rack assembly, please consider that, during operation, the ambient temperature, the mechanical loading and the electrical potentials will be different from those of devices which are not mounted into a rack.

왘 Make sure that the ambient temperature within the rack does not

exceed the permissible temperature limit specified in the specifications (see page 51).

왘 Ensure sufficient ventilation; if necessary, provide additional ventila-

tion.

왘 Make sure that the mechanical loading of the rack is even. 왘 When connecting to the power supply, observe the information indi-

cated on the type plate. Avoid circuit overloading. If necessary, provide overcurrent protection.

왘 When rack mounting, please note that intrinsically harmless leakage

currents of the individual mains units may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.

Rack mounting

one receiver

To mount the receiver into a rack, you require the GA 3 rack adapter (see “Accessories and spare parts” on page 49):

왘 Secure the rack mount “ears”  of the GA 3 rack adapter to the

receiver in the same way as described for the stacking elements (see page 11).

왘 Secure the blanking plate of the GA 3 rack adapter to one of the rack

mount “ears”  using two recessed head screws (M 6x10).



Putting the receiver into operation



왘 Connect the antennas. You have the following options:

– You can connect the supplied rod antennas  to the rear of the

receiver (see page 13). In this case, insert the two blanking plugs into the holes of the blanking plate.

– You can use the AM 2 antenna front mount kit (see “Accessories

and spare parts” on page 49) and mount the rod antennas to the blanking plate .

Rack mounting

two receivers

To mount the receiver into a 19” rack:

왘 Slide the receiver with the mounted blanking plate into the 19” rack.

왘 Secure the rack mount “ears”  to the 19” rack.

If you are using the supplied rod antennas:

왘 Align the antennas in a V-shape to obtain the best possible reception.

When rack mounting two receivers side by side, you can only front mount the antennas when using the ASA 1 antenna splitter in conjunction with the AM 2 antenna front mount kit and an additional GA 3 rack adapter (see “Accessories and spare parts” on page 49).

We recommend using remote antennas.

Putting the receiver into operation

To mount the receivers into a rack using the GA 3 rack adapter:

왘 Place the two receivers side by side upside-down onto a flat surface.

왘 Secure the jointing plate to the receivers using six recessed head

screws (M 3x6).

The rack mount “ears” are mounted instead of the stacking elements:

왘 Secure the rack mount “ears” to the receivers in the same way as

described for the stacking elements (see page 11).

To mount the antennas:

왘 Use remote antennas, if necessary in conjunction with the ASA 1

antenna splitter (see “Accessories and spare parts” on page 49).

To mount the receivers into the rack:

왘 Slide the receivers into the 19” rack.

왘 Secure the rack mount “ears” to the 19” rack.

Putting the receiver into operation

Connecting an amplifier/mixing console

The receiver’s ¼” (6.3 mm) jack socket  and XLR-3M socket  are connected in parallel, allowing you to simultaneously connect two devices (e.g. amplifier, mixing console) to the receiver.

왘 Use a suitable cable to connect the amplifier/mixing console to the
