User manual SENNHEISER ASA 3000

[. . . ] Due to the built-in antenna boosters, the signals are routed without loss the the connected receivers. The active antenna splitter allows you to make receiver systems with up to 16 channels. Areas of application: Multi-channel RF installations (fixed or mobile) Permanent installations in small conference centres and similar venues 2 Safety information The 2 x 1:8 active antenna splitter must only be set up and connected by an electrical engineering expert. This must only be done by authorized personnel and is all the more important for units connected to AC outlets. [. . . ] Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of discoloration, since we don't know your furniture. To protect your furniture, we recommend placing the unit on a non-slip pad. Connecting the antennas You can connect the following antenna types to the BNC sockets and º of the input modules: two GZA 1036 or A 2003-UHF passive antennas or º ² two A 12 active antennas or two GZA 1036 passive antennas with AB 1036 antenna boosters. The ASA 3000 routes the antenna signals without loss to the respective antenna outputs. Notes: The ASA 3000 is delivered with the DC supply voltage for active antennas or antenna boosters turned on. The two LEDs DC FEED ANT A ³ and DC FEED ANT B · light up green. ³ · 6 ¸ If you use passive antennas only, the DC supply voltage can be turned off. To do so, remove the two input modules (see "Exchanging the input modules" on page 7) and set the two switches DC-Feed ANT A and DC-Feed ANT B ¸ to position "OFF". Connecting the receivers Up to eight receivers, e. g. Use BNC cables to connect the receivers to the BNC sockets ´ and ¾ as follows: ¾ ´ First receiver: Diversity section "A" to A1, diversity section "B" to B1. Second receiver: Diversity section "A" to A2, diversity section "B" to B2. Connecting the mains cable Connect the mains cable to the IEC mains socket µ and to the mains. The unit is ready for operation as soon as it is connected to the mains. µ Note: The ASA 3000 can be connected to any mains power supply with 100 V to 240 V AC (50 to 60 Hz). Exchanging the input modules The unit is fitted with two wideband input modules (470 to 870 MHz) which are suitable for most applications. However, to ensure optimum reception reliability, we recommend using two selective input modules (60-MHz window) (see "Accessories" on page 10). 7 When using the selective input modules: Make sure that all transmitters and receivers of your transmission system operate within the frequency window of the selective input modules!When using the wideband input modules: Use an active antenna (e. g. A 12 AD antenna) or an antenna with antenna booster (e. g. GZA 1036 antenna with AB 1036 antenna booster). To exchange the input modules: Use a crosstip screwdriver to loosen the screw of the catch for the input modules ¶. To remove the input modules ² and º, plug a BNC connector into the input modules` BNC sockets and pull hard (!) at the BNC connector. ¶ º ¶ ² Insert the new input modules and tighten the screw of the catch ¶. 8 Trouble shooting The LED POWER » does not light up The unit is not powered. Disturbed reception or no reception Possible causes: Transmitting antennas are not within the reception area Transmitters or receivers are not turned on Transmitter batteries are not inserted or batteries are low The antennas are not connected correctly The connecting cables are defective Too high cable attenuation due to too long antenna cables or wrong type of antenna cable The selected transmission and receiving frequencies are not within the frequency window of the selective input modules (optional) and antenna boosters (optional) When using active antennas or antenna boosters, the supply voltage must be turned on (see "Connecting the antennas" on page 6).
