RTS SSA-424 Dual Digital Hybrid- USED



The SSA-424 Dual Digital Hybrid intervaces two, 2- wire intercom lines to two, 4-wire intercom lines. Unlike earlier analog hybrids, the SSA-424 features advanced digital signal processing to achieve automatic nulling of the 2-wire lines. Plus, each hybrid features convenient peak-reading level meters to quickly match the levels between the lines that are being interfaced. The result is easy and accurate setup. With the SSA-424, all need for test tones, nulling adjustments and ducking adjustments have been eliminated.

Two Independent Hybrids: Interface two separate 2-wire lines to two separate 4-wire lines.

Automatic Nulling: Digital hybrids eliminate all nulling and ducking adjustments. Quick, trouble-free setup. Puts an end to concerns about echo and feedback when interfacing 2-wire lines.

Peak Reading Level Meters: Quick and accurate visual audio level adjustment. No extra setup equip- ment or guesswork is required.

Direct ADAM/Zeus Audio Connection: Accepts standard ADAM/Zeus DB9 or RJ11 keypanel cables.

Transformer Isolated: All audio inputs and outpus are transformer isolated to prevent ground loops and hum.

Call Signal Option: Detects call signals from any of the compatible 2-wire intercom systems, and then provides a +5VDC output to the 4-wire intercom system. Accepts a contact closure input from the 4- wire system and converts it to the call signal format required by the 2-wire system. The SSA-424 can be directly connected to an ADAM, ADAM CS, or Zeus GPI (General Purpose Interface). GPI inputs can be programmed to activate call signals and audio paths to any of the available types of communication within the 4-wire system, including intercom ports, camera ISO circuits, IFB circuits, etc. GPI outputs can be set up to place calls only from a specific keypanel within the 4-wire system, or from any keypanel within the 4- wire system that wishes to call the 2-wire system.

Half-rack Wide, 1RU High: Two SSA-424’s fit into a single rack space. Compatible with RTS TW rack mount hardware. Can be mixed with other TW equipment.

Universal Power Pack: Ready for worldwide use. Automatically accepts any mains voltage from 100- 250 VAC, 50/60 Hz. Power pack equipped with locking DIN connector for attachment to the SSA- 424.
