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.

Easy to configure complete room combining
Eight (8) Mic/Line Inputs with filters, EQ, and feedback elimination into Gain-sharing Automixing, assignable to any of the eight rooms or used as a common paging source.
Four (4) Line Inputs with filters, EQ and Automatic Gain Control (AGC), handle Background Music (BGM) with ease.
Eight (8) Outputs: Route audio to as many as eight (8) unique rooms, common or overflow areas.
Wizard-driven software set-up; network ready.

INPUTS

Number of Inputs: Twelve (12) total; Eight (8) switchable balanced mic or line, Four (4) balanced line level

Connectors: Phoenix

Nominal Input Level: +4 dBu line or -40 dBu mic level (software selectable) with 20 dB of headroom

Input Gain: +20 dB, +40 dB or +50 dB, mic inputs; +0 dBu or +11.8 dBu, line inputs (both via internal jumpers)

Maximum Input Level: +23 dBu

Input Impedance: > 4 kΩ balanced, > 2 kΩ unbalanced

CMRR: > 55 dB @ 1 kHz, unity gain

Mic Pre-amp EIN: > -127 dBu, 22 Hz - 22 kHz, 100 Ω source impedance

OUTPUTS

Number of Outputs: Eight (8) balanced line level

Connectors: Phoenix

Nominal Output Level: +4 dBu line level with 20 dB of headroom. For unbalanced analog output, float (do not connect) the minus output terminal. Unbalanced usage results in 6 dB lower output level.

Maximum Output Level: +24 dBu

Output Impedance: 200 Ω balanced, 100 Ω unbalanced

SYSTEM

Sample Rate: 48 kHz

Frequency Response: 20 Hz - 20 kHz, +/- 0.5 dB

Dynamic Range: > 110 dB (A-Weighted), input to output

THD+Noise: -85 dB (un-weighted); 1 kHz @ +22 dBu with 0 dB gain

Interchannel Crosstalk: > -90 dB @ 1 kHz, typical

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.

Certifications: UL 60065, cUL 60065, IEC 60065, EN 55103-1, EN 55103-2, FCC Part 15, RoHS
