DAX-‐16 Installation & Operation Manual Browser Support The DAX-‐16 uses new features of HTML5. It streams audio using ADPCM, which results in 25% of the bandwidth required for PCM. It also streams audio using PCM if bandwidth is available.
DAX-‐16 Installation & Operation Manual Front Panel The DAX-‐16 front panel includes signal presence indicators for each output. The LED lights when a channel has an output level of 10.7mV RMS or higher.
DAX-‐16 Installation & Operation Manual 3. Audio output number 8. This drives a two channel amplifier with outputs 8A and 8B. It also accepts two return signals (Vmon for A and B) to monitor the amplifier output. Use a standard DE-‐15 to DE-‐15 cable to connect this to an amplifier.
