SSA-424 u ser m anual 5 1 description and specifications 1.1 g eneral d escription 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. compatible 2-wire intercom systems include rts? tw, audiocom ? , and clear-com ? . compatible 4- wire intercom systems include telex?s adam?, adam?cs, and zeus? digital matrix intercom systems. the SSA-424 is also available with optional call signal interfacing. this option provides bidirectional call signal compatibility between the 2-wire and 4- wire intercom systems. with features like digital signal processing, peak- reading level meters and optional call signal interfac- ing, the SSA-424 dual digital hybrid assures ease of setup and maximum transparency between intercom systems. 1.2 g eneral f eatures 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. aux j4b j3b j2b j1b j1a j2a j3a j4a aux 4 wire system 4 wire system 2 wire system telex communications, inc., made in u.s.a. -15 -12 -9 -6 0 +3 +6 +9 +12 level set system b -15 -12 -9 -6 -3 0 +3 +6 +9 +12 4w 2w to to SSA-424 4w level ref sel 12 bal 2w chan sel level set system a -3 4w 2w to to power 4w level ref sel 12 bal 2w chan sel 1 2 bal off off tm rtn +5v rtn +15v -15v -15v 0.3a +15v 1.6a +5v 3a j5 power 0db +4db +8db +12db -10db 0db +4db +8db +12db -10db 1 2 bal off off figure 1.

6 SSA-424 u ser m anual 1.3 f ront and b ack p anel d escriptions 1.3.1 f ront p anel there is a power on/off and call indicator at the left of the front panel. this indicator lights continuously when the SSA-424 is turned on and flashes when an incoming call signal is detected. the remainder of the front panel is divided into controls and indicators for the two separate hybrids, labeled system a and system b. for each hybrid, there is a 10-segment, peak reading level meter to display the 4-wire output level (to 4w). there is a recessed level set control to the left of the 4-wire meter (level set) and there is also a recessed, 5-position range select control for the 4-wire output (4w level ref sel). under the 4-wire meter, is an identical meter for the 2-wire output level, and there is a recessed level set control for the 2-wire output to the left of the meter. under the 2-wire meter, there is a recessed, 5-position selector. the selector has two off positions for when no 2-wire input is connected. the three remaining switch positions select the 2-wire system as follows: position 1 selects rts tw channel 1; position 2 selects rts tw channel 2 or a clear-com channel; the bal position selects an audiocom balanced channel. there are 3 led indicators to display the current selection (2w chan sel). 1.3.2 b ack p anel the power pack connector is located at the right end of the back panel. this is a locking din connector. the remainder of the back panel is divided into connectors for the two separate hybrids. connectors are labeled with ?j? numbers followed fy ?a? or ?b? to indicate system a or system b. for each hybrid, there is an aux connector. this is used to connect to/from the optional call signal card. below the aux connector, there are both a db9f connector and an rj11 connector for 4-wire intercom connection. these are directly compatible with standard adam/ zeus keypanel cables. next to the 4-wire connectors, there is a 3-pin female xlr audio connectorfor connection to the 2-wire intercom system. the pin- out of this connector is determined by the position of the tw chan sel control on the front panel. 1.4 s pecifications 2-wire ports input/output impedance: 5,000 ohms, nominal operating level: -10dbu to 0 dbu, nominal level adjustment range: 12db 4-wire ports input impendance: 10k ohms, nominal output impedance: 200 ohms operating levels: -10 dbu, 0 dbu, +4 dbu, +8 dbu, +12 dbu system to system frequency response:200 hz to 4.5 khz, +1/-6db s/n ratio (ref 1 khz, 0 db@2-wire): tbd crosstalk: tbd environmental operating temp: -20c to 50c (-4f to 122f) storage temp: -40c to 85c (-40f to 185f) humidity: 0 to 95%, non-condensing mains voltage 100 to 250 vac, 50/60 hz dimensions 1.72?
