The Link Electronics 812-OP/E is a digital and analog audio signal generator module. This unit is designed to perform two basic functions. The first basic function of this module is to produce a single AES/EBU digital audio signal for use as a digital audio reference or digital tone source. Second, it is to produce a balanced stereo analog audio signal of up to +28dBu for use as a test tone.
The user may select the amplitude and frequency of the audio tone from a fixed set of 8 combinations. Within this set of eight there are three frequencies (1KHz, 400Hz, 60Hz) and three levels (0dBFS, -10dBFS, -20dBFS). With this, the module has the ability to produce "digital silence" while producing one of the eight combinational tones on the output.
LEDs are used to indicate tone frequency and level, digital silence, lock status, and power indication.
This device is a rack card that operates within the SPG-812 frame.
