Expand your wireless coverage with the Sennheiser ACA 3, a dual-channel 4:1 antenna combiner compatible with all stationary Sennheiser analog and digital receivers. Well suited for use in larger venues, houses of worship, and broadcast installations with distributed antenna systems, each channel of the unit allows you to combine and distribute the RF signal from up to four connected antennas to a receiver. The front panel offers switchable DC power controls for the eight BNC inputs (four for each receiver) for active antennas or head amps. The RF signal from each antenna input can also be switched off independently, allowing you easily isolate unused antennas.

• Switchable DC supplied on each antenna input for head amps or active antennas including the AB 3, AB 3700, A12AD, and AB 9000
• RF from each of the eight antenna inputs is switchable to isolate unused antennas
• LEDs indicate input state: RF on, DC on, and DC current overload (for a faulty ‘short circuit‘ antenna cable)

Q: 2. Can two of these EW-D active antenna splitters be daisy chained so that 6 receivers can share a single pair of antennas?

A: Yes, the Sennheiser EW-D ASA 4-Way Active Antenna Splitter with DC Distribution for EW-D Wireless Systems can connect to another unit using the "RF Out A" BNC connection of one unit into the "ANT RF in B" connection of a second unit.

Q: 3. Can I use this system with the 1/4'' and 1/2'' antennas? I don't really need the very big antennas. Thank you

A: You can use B&H # SEHALFWAVEDQ for compatibility with the Sennheiser EW-D ASA.

Q: 4. Is this compatible with EW300 receiver?

A: Yes, that's what I use it on.

Q: 5. Will this work for the EW-DX systems? The description says ED-D.

A: Yes, the Sennheiser EW-D ASA 4-Way Active Antenna Splitter with DC Distribution for EW-D Wireless Systems is compatible for use with Sennheiser EW-DX EM 2 Two-Channel Digital Rackmount Receivers. The EW-DX EM Receiver is the two-channel version of the EW-D Receiver, which is singe-channel.

Q: 6. Is the power supply 110~220v automatic?

A: Yes

Q: 7. Are the antenna systems from the analog wireless systems (G3/G4) compatible with the EW-D series receivers, or do I now need to get this splitter for my antennas to work?

A: No, the antenna systems for the G3/G4 series analog wireless systems are not compatible for use with the EW-D series systems. You will need to use the EW-D ASA for EW-D series wireless systems.

Q: 8. How long of a cable run do you need to start thinking about using this?

A: Depends on the type of cable being used. Basic RG8X cable with passive antennas would be 25 feet. Higher quality cabling like RG213 or 9913 can be run up to 100 feet.

Q: 9. We ordered this as a replacement part but it is the 6 model and we need the 12 . I do not see the 12 on your site, is it available?

A: Yes it is parallax free. Where the parallax turret would normally be is the adjustment for reticle color and brightness are selected using a dedicated side turret.

Q: 10. Can this work with R- and Q-band receivers simultaneously? The 1/2 wave antenna only supports either R or Q band.

A: The Sennheiser EW-D ASA covers the Q, R, and S frequency ranges, from 470 to 694 MHz. The limiting factor in terms of frequency range would be the antenna used.
