Zaxcom RX-8 8-Channel Receiver Interface

Small enough for a bag, the Zaxcom RX-8 is an 8-channel receiver interface that holds two MRX slot-in receiver modules behind a built-in MicPlexer.

With two MRX414 modules it receives up to eight transmitters, and with two MRX214 modules up to four. The modules swap in any combination at any time, so the RX-8 changes with each day’s needs.

RF and Frequency Coordination

The built-in MicPlexer adds 3 dB of RF gain and feeds the antennas to both modules and to further receivers on the two SMA RF outputs. A front-end filter with a 35 MHz window blocks interference across 512 to 698 MHz.

A frequency scanner with Auto-Pick software chooses clear frequencies at the push of a button. Four OLED displays hold the menus for each receiver pair.

Outputs and ZaxNet

Eight channels of analog or AES digital audio leave on a DB25 connector wired to the Tascam standard. The RS422 port pairs the RX-8 with an IFB300 or TRXCL4, so the RX-8 can re-tune transmitters to match and adjust their gain over ZaxNet.

Dante on the RX-8D

The RX-8D adds Dante with Power over Ethernet for a receiver placed on set. It sends 16 channels back to the cart: 8 from its modules and 8 from four AES pairs on the DB25.

It also brings 4 balanced analog channels from the cart for IFB, voice of God, or monitoring, and one of them can carry timecode to the BNC jack for jamming slates. On PoE, a 12 V output supplies up to 1 A to other receivers or transmitters.

Power

The RX-8 runs from 9 to 18 V DC through a Hirose connector. On the RX-8D, the Hirose input backs up PoE and takes over without a break if PoE fails.
