Antenna Splitter 1:4

Instructions for use

Brief description

The ASP 2 passive RF antenna splitter has been designed for routing antenna signals to several receivers in a multi-channel system, i.e. up to four diversity receivers are supplied with the signals of only two antennas. The antenna splitter incorporates DC distribution for powering up to four receivers in addition to two antenna boosters via a single mains unit. By linking two ASP 2 antenna splitters, an 8-channel system can be operated with only two antennas. By using the GA 2 rack adapter, two antenna splitters or one antenna splitter and one rack-mount receiver (e.g. EM 100 G2, EM 300 G2 or EM 500 G2) can be mounted into a 19" rack. Areas of application: ! Small to medium RF installations (fixed or mobile) ! Permanent installations in small theaters, conference centers and similar venues

Delivery includes

! 1 ASP 2 antenna splitter ! 1 set of plastic feet ! Instructions for use

Safety instructions

Caution! Never open the unit! If units are opened by you in breach of this instruction, the warranty becomes null and void.
Attention! Make sure that the air vents of the unit are not covered or blocked! Keep the unit away from central heating radiators and electric heaters!
Caution! Set up the unit on an even surface or mount it into a rack! Lay the cables in such a way that no-one can stumble over them!
Attention! Keep liquids and small parts which conduct electricity away from the unit! Use a slightly damp cloth for cleaning the unit. Do not use any solvents or cleansing agents!

Putting the unit into operation
The below connection diagram shows the connections for a 4-channel diversity system.
Setting up the unit The unit is suitable for use as table top or can be mounted into a rack.
For mounting the unit into a 19" rack, use the GA 2 rack adapter (optional accessory). For table top use, fix the plastic feet to the base of the unit. Note: 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.

Connecting the antennas

You can connect the following antenna types to the antenna inputs and : ! two A 1031-U or A 2003-U passive antennas or ! two A 12 active antennas or ! a combination of passive antenna (A 1031-U or A 2003-U) and antenna booster (AB 2).
Connecting the receivers You can connect up to four rack-mount receivers (e.g. EM 100 G2, EM 300 G2 or EM 500 G2) to the ASP 2. The splitter incorporates DC distribution for powering the receivers.
Pass the cables coming from the antenna spitters DC outputs through the cable grips at the rear of the receivers. Insert the hollow jack plugs into the sockets of the receivers. Connect the BNC cables and of the antenna splitter to the receivers as follows: ! Antenna outputs (OUT A) to antenna inputs (ANT I) ! Antenna outputs (OUT B) to antenna inputs (ANT II)

EM 500 G2

Note! We recommend protecting unused RF outputs with a 50 terminator in order to keep to the specified distribution attenuation.
Connecting the mains unit The NT 1 mains unit can power up to four receivers. The DC power is also available at the antenna inputs for powering two optional antenna boosters.
Pass the cable through the cable grip. Insert the DC connector on the power supply cable into the DC input. Note:

The antenna splitter has no power switch.

If problems occur.

Error checklist Problem Receivers cannot be switched on Disturbed reception or no reception Possible cause Possible solution
Receivers are not powered Check the connections of the mains unit or the DC connections Transmitting antennas are Reduce the distance not within the range of the between transmitter and receiving antennas receiving antennas Transmitters or receivers are not switched on Antennas are not connected correctly Connecting cables are defective Too high cable attenuation due to too long antenna cables or wrong type of antenna cable Switch the transmitters or receivers on Check the antenna connections Replace the connecting cables Only use the recommended antenna cables (see Accessories on page 21) or use shorter antenna cables Transmitters and receivers See operating manual of the transmitter or receiver are not on the same frequency
If problems occur that are not listed above or if the problems cannot be solved with the proposed solutions, please contact your local Sennheiser agent for assistance.

The guarantee period for this Sennheiser product is 24 months from the date of purchase. Excluded are accessory items, rechargeable or disposable batteries that are delivered with the product; due to their characteristics these products have a shorter service life that is principally dependent on the individual frequency of use.

Without this proof (which is checked by the responsible Sennheiser service partner) you will not be reimbursed for any repairs that are carried out. Depending on our choice, guarantee service comprises, free of charge, the removal of material and manufacturing defects through repair or replacement of either individual parts or the entire device. Inappropriate usage (e.g. operating faults, mechanical damages, incorrect operating voltage), wear and tear, force majeure and defects which were known at the time of purchase are excluded from guarantee claims. The guarantee is void if the product is manipulated by nonauthorised persons or repair stations. In the case of a claim under the terms of this guarantee, send the device, including acces-sories and sales receipt, to the responsible service partner.
