Sennheiser ASA 3000 Instructions for Use - Page 7

If you use passive antennas only, the DC supply voltage can be turned off. To do so, remove the two input modu- les (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. EM 3031, or eight twin receivers, e.g. EM 3032 or EM 3532, can be connected. ̈ Use BNC cables to connect the receivers to the BNC sockets ´ and ¾ as follows: First receiver: ¾ ´ Diversity section "A" to A1, diversity section "B" to B1. Second receiver: Diversity section "A" to A2, diversity section "B" to B2. etc. Connecting the mains cable ̈ Connect the mains cable to the IEC mains socket µ and to the mains. The ASA 3000 has no power switch. The unit is ready for operation as soon as it is connected to the mains. Note: µ 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
