MB-WT4

The IR wireless system shall consist of an IR (Infra-Red) tuner in a 1U,1/2 rack housing measuring 8.3” (W) x 1.7” (H) x 8.3” (D) and weighing 1.4 lbs. The unit is capable of being rack-mounted via an optional rack kit (MB-WT3). The tuner shall operate on two independent channels, each selectable to one of two available IR frequencies in the 3 mHz range (3.10 & 3.35 mHz). Each channel shall have an independent front panel output level control and corresponding ¼” output connector, one of which can function as a mix of both channels. The rear panel shall also have two BNC-type connectors for remote IR receivers, each supplying 24VDC for receiver operation. The unit shall power from a supplied external 24VDC power adapter and shall consume a max of 15W. The unit shall be called the TOA IR-702T.
