3. Inputs and Controls 1. INPUT Toggle switch selects between the analog (A) and digital (D) inputs. 2. [ANLG] XLR connector is designed to receive analog balanced line level audio signal from sources such as preamplifiers, sound cards, monitor controllers and mixing consoles. Pin 1 is tied to chassis ground. Pins 2 & 3 are fully floating differential inputs. Pin 3 must be referenced to ground for single ended input signals. The analog signal is converted to 24bit/192kHz digital audio via a precision, ultra-high-fidelity analog to digital converter section inside the MiniMain12. 3. [AES3] XLR connector is designed to receive digital AES3 standard audio signal from sources such as sound cards and digital audio workstations. The digital signal must be attenuated at the source In The Box. Non-attenutated digital audio will produce very high sound pressure levels that can damage your ears and potentially the speakers. 4. [CHNL] Toggle switch selects between the left (L) or right (R) channel inside the AES3 data signal. 5. LEVEL Eight position rotary switch adjusts the level of both the Analog and Digital inputs in precise dB increments from +dB to dB. 6. SUB Three position toggle switch adjusts the level of the subwoofers from dB to +dB or dB. 7. VOICE mm stereo phone jack for connection to Voice Selector Switch. See Section 7 for Voice Emulation setting details. The default setting with no switch connected is Flat. 8. USB The universal serial bus connector is for factory adjustments and calibrations. This connector is not an audio input.
