While some audio amplifiers have analog audio detection circuits, these are not always reliable, especially at lower listening levels. Because the DAT1 is monitoring the digital signal the 12-volt trigger is activated immediately, as soon as the music starts and at any volume level.
The 12-volt DC trigger standard is very useful to custom installers, audio enthusiasts, and pro audio users alike, because it uses inexpensive 3.5mm mono cables to send turn-on/off commands to external amplifiers, smart home controls systems, cooling fans, dropping projector screens and other accessories. Unfortunately, most streaming devices, TVs, CD/DVD/Blu-ray players, video game systems, computers and others don’t have a 12-volt trigger output. The Bobwire DAT1’s on-board software analyzes the optical digital signal to determine when the connected device is powered on, paused or playing music, and then activates one of the two 12-volt outputs accordingly.
Additional features include an optical audio looping output so that the digital signal may be passed on to another DAC or surround sound receiver. The analog audio output utilizing a high resolution 24-bit, 192-kHz digital to analog converter. The 12-volt outputs are rated to 500 mA each which allows them to directly drive high power devices such as cooling fans and multiple relays. LEDs are provided for each of the 12-volt outputs to aid in troubleshooting. Included in the box is the DAT1 device, high-current power supply, 3-foot optical cable and 6-foot trigger cable.
