Description
8-input Audio Switcher With Integrated Triggers, Relays, and Silence Sensor
The Broadcast Tools ACS 8.2 Plus provides matrix audio switching of 8 stereo inputs to 2 stereo plus 2 mono outputs. Any input assigned to output one has fading capabilities. Matrix switching allows any/or all inputs to be assigned to any/or all outputs. The ACS 8.2 Plus is equipped with a front panel monitor selection switch. This allows the user to select which stereo output the VU meters and headphone amplifier monitors. Optional* AGC modules may be added to each output channel to maintain consistent levels. The ACS 8.2 Plus may be controlled via front panel switches, contact closures, 5-volt TTL/CMOS logic and/or the multi-drop RS-232 serial port (An optional USB adapter is available). Installation is simplified with plug-in euroblock screw terminals.
The ACS 8.2 Plus is the ideal hardware to add to BSI Simian, when stations are fed by a number of different satellite network providers. Simian can easily switch between audio inputs and / or respond to incoming trigger closures.
If you are familiar with the Broadcast Tools SS 8.2, the ACS 8.2 Plus is it’s upgraded replacement. Some of the new features are a fully digital audio signal path and the ability to fade between input channels on output 1. Trigger and relay terminals are now on de-pluggable screw terminals for easy installation.
Typically, output 1 is fed direct to the Air chain, while output 2 is wired to the computer record input. This allows one satellite source to be fed to Air, while another is recorded in the background.
An internal stereo silence sensor with front panel LED indicators and relay with adjustable threshold and duration can be used to monitor the incoming satellite feed and trigger Simian to provide a backup service in case of failure.
Each input has a variable level control, so that the volume from all networks can be matched, a task made easier with the front panel LED VU Meters.
There’s also a Stereo headphone amplifier with front panel output selection switch, headphone jack and level control. Outputs are also provided for a Stereo powered speaker output with front panel level control
The ACS 8.2 Plus has enough incoming triggers to respond to satellite network feeds as well as EAS alarms and mixing console remote starts.
