Congratulations on your purchase of the A/V Conference Room Processor. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies. Gefen’s reliable, plug-and-play products supplement cross-platform computer systems, professional audio/video environments and HDTV systems of all sizes with hard-working solutions that are easy to install and simple to operate.

The Gefen A/V Conference Room Processor

Integrating multiple audio/video sources in a professional setting has never been easier. Gefen’s new A/V Conference Room Processor with built-in audio ampliﬁ er connects set top boxes, Blu-ray players, gaming consoles, computers and more. Video is scaled and output in HDMI format with cinema-quality scaling up to 2K or 1080p Full HD resolution, supporting large-scale HDTV displays. Multichannel surround audio (Dolby® or LPCM) is mixed down to two-channel stereo plus support for a powered subwoofer. A built-in two-channel audio ampliﬁ er delivers 25 watts per channel from digital and analog sources, ideal for creating high-ﬁ delity sound in the conference room environment. Two speakers may be connected directly to the ampliﬁ er binding posts for “plug and play” installation in any confer- ence room, educational facility or presentation venue.

How It Works

Connect each video input source and corresponding audio source to connectors on the front or rear panel. Power up the A/V Conference Room Processor. The buttons on the front panel are used to select the active A/V source. Use the LCD menu system to select the scaler output resolution and desired A/V processing functions. The A/V Conference Room Processor will convert the selected A/V inputs to HDMI video output with two-channel analog line-level and speaker-level with powered subwoofer support.

INSTALLING THE IR REMOTE CONTROL UNIT

Installing the Battery

1. Remove the battery cover on the back of the IR Remote Control unit.

2. Insert the included battery into the open battery slot. The positive (+) side of the battery should be facing up.

3. Replace the battery cover.

The Remote Control unit ships with two batteries. One battery is required for operation and the other battery is a spare.

CAUTION: Risk of explosion if battery is replaced by an incorrect

type. Dispose of used batteries according to the instructions.

IR REMOTE CONTROL UNIT CONFIGURATION

Setting the IR Remote Control Channel

In the event that IR commands from other remote controls interfere with the supplied IR Remote Control unit, changing the IR Remote Control’s IR channel will ﬁ x the problem. The IR Remote Control unit has a bank of DIP switches used for setting the IR channel.

The DIP switch bank is located underneath the battery cover.

1 2

Channel 2:

Channel 0: Default

Channel 1:

Channel 3:

Battery compartment of the IR remote showing the exposed DIP Switch bank between the battery chambers.

It is important that the IR channel on the Remote Control unit, matches the IR channel set on the Gefen A/V Conference Room Processor. For example, if both DIP switches on the IR Remote Control unit are set to IR channel 0 (both DIP switches down), then the A/V Conference Room Processor must also be set to IR channel 0. See page 36 on how to change the IR channel on the A/V Conference Room Processor.
