Drawmer 4X4R Rackmount Active Splitter

Input Channels Explained

Each of the four channels are almost identical, with controls including:

• Mic/Line: switches the level of input between mic or line with LED indication. When in the line position, the phantom power switch is bypassed, the input has a 20 dB pad, and the input impedance changes to >10 kilohms.
• Phantom Power: this switch provides +48V phantom power down the XLR cable to microphones that require it.
• Gain: a twelve-position switch adds gain in 6 dB steps from 0 to +66 dB, making it incredibly easy to replicate on each channel.
• V.U. Meter: each channel has a six LED VU meter, covering a range of -20 to +18 dB.
• Listen: this switch routes the input from that particular channel to the headphone section for monitoring. Each channel can be activated separately (solo) or all can be monitored at once if preferred.

Linking

In certain situations, four outputs may not be adequate, for example at a news conference where each reporter requires a feed, and for this reason Drawmer has incorporated a very versatile and intuitive linking system that effectively converts the 4X4 into a pressbox. Linking is performed via three switches, so there is no need to open the unit up to swap jumpers, or worse still, re-solder connections.

If a link switch is active, the input feeding the four outputs of that particular channel is disabled, and re-routed to the input of the previous channel. If the link switch of that channel is also active, then it is re-routed further to the previous channel. In this way any combination of linking can be available.
