Benefits & Features

• Flexible wizard driven room configuration setup software.
• Support for Symetrix ARC wall panel remotes for simple, intuitive end-user operation.
• 8 switchable mic or line inputs with filtering, EQ, feedback elimination, and gain-sharing automixing; assignable to any of 8 rooms.
• 4 line level background music (BGM) inputs with filtering, EQ and Automatic Gain Control (AGC).
• 8 outputs with programmable highpass and lowpass filters, 8-band parametric EQ, limiting and delay.

Product Details

Selectively combine or separate automixing, paging and background music in up to eight (8) rooms in hotels, banquet halls, schools, and conference venues.

Hospitality and meeting centers demand easily operated, yet sophisticated audio systems. Complete signal processing, automixing and combining of eight (8) microphones and four (4) background music (BGM) sources into as many as eight (8) rooms, each with comprehensive loudspeaker management. Combinations of audio, page, and BGM routing, including non-adjacent spaces, are assigned in the setup software.

For real time user control the Symetrix ARC-SWK wall panel (sold separately) is perfectly suited for audio source selection and volume control. Multiple ARC-SWK’s dynamically synchronize as spaces are combined and separated. Preset room combinations can be recalled from the 788’s front panel, the ARC-2i wall panel, or a third-party control systems. “Soft wall” sensors accommodated with eight (8) analog control inputs for a simple triggering of combinations.

Software Wizards effortlessly guide connection, wall panel programming, and graphical layout of the rooms and their relationships.

MECHANICAL DATA

Space Required:
1U (WDH: 48.02 cm x 22.15 cm x 4.37 cm / 18.91 in x 8.72 in x 1.72 in), depth is specified from front panel to back of connectors.
Allow at least 3 inches additional clearance for rear panel connections. Additional depth may be required depending upon your specific wiring and connections.

Electrical:
100-240 VAC, 50/60 Hz, 25 Watts maximum.
No line voltage switching required.

Ventilation:
Maximum recommended ambient operating temperature is 30 C / 86 F. Ensure that the left and right equipment sides are unobstructed (5.08 cm, 2 in minimum clearance). The ventilation should not be impeded by covering the ventilation openings with items such as newspapers, tablecloths, curtains, etc.
