DAS 8.4 Plus Installation and Operation Manual
DESCRIPTION
Product Description
The Broadcast Tools DAS 8.4 Plus provides AES/EBU digital audio rout-
ing/switching of any one of eight AES/EBU inputs to any/or all four AES/EBU out-
puts. The DAS 8.4 Plus may be used in Multicast applications, where an AES
enabled EAS device assigned to input eight is routed to all four outputs via a con-
tact closure or serial command. When the alert/test is completed, the DAS 8.4 Plus
will return to its previous I/O configuration. The DAS 8.4 Plus may be controlled
via front panel switches, contact closures, 5-volt TTL/CMOS logic and/or the multi-
drop RS-232 serial port. The front panel is equipped with input and output selection
pushbuttons, output assignment LED’s, sample rate LED indicators and a headphone
amplifier with a front panel T/R/S/ jack and level control. Additional features: 96
KHz AES receiver, a 24-bit D/A converter with analog balanced stereo output, head-
phone amplifier and 16 x 16 GPIO port. Installation is simplified with plug-in
euroblock screw terminals. 1-RU chassis
Additional Features
• Routing type switching, any one input may be assigned to any/or all outputs.
• Multicast function and remote control port
• Logic functions via microprocessor and non-volatile memory
• Internal digital/analog audio activity/silence sensor monitors any one of four
output channels selectable with the front panel monitor switch. The unit is
equipped with four front panel sample-rate LED indictors, SS, AES/EBU
Digital Error and stereo 10-LED meters; adjustable analog Silence Sensor/AES
Digital error alarm delay and restore duration. Analog silence sensor sensitivi-
ty is factory set at -30db.
