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 chas-
sis 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 preci-
sion, ultra-high-fidelity analog to digital converter section inside the MicroMain35 Gen2.
3. [AES3] XLR connector is designed to receive digital AES3 standard audio signal from sources such as
sound cards and digital audio workstations (DAW). The digital signal must be attenuated at the
source (“In The Box”).
Caution: Non-attenuated digital audio will produce very high sound pres-
sure levels that can potentially damage your hearing and/or the speakers. Each AES3 XLR carries
both left and right audio signals. For stereo or multiple speaker operation the monitor output sig-
nal must be assigned to two or more AES3 output XLRs within the DAW. Otherwise, a passive AES
splitter or an active AES distribution amplifier is required to deliver signal from a signal from a sin-
gle AES output XLR. Use the CHNL switch on the back of each speaker to select appropriate left or
right audio signal from the stereo AES signal.
4. [CHNL] Toggle switch selects between the left (L) or right (R) channel coming from the AES3 data
signal. This switch is only active when the INPUT toggle is in the (D) position.
5. [LEVEL] Eight position rotary switch adjusts the level of both the Analog and Digital inputs in pre-
cise 1dB increments from +3dB to –6dB.
6. [SUB] Three position toggle switch adjusts the level of the subwoofers from 0dB to +2dB or –2dB.
7. [VOICE] 3.5mm stereo phone jack for connection to MEME™ Selector Switch. See Section 9 for
MEME™ settings and connection details. The default setting with no switch connected is Flat.
8. [USB] The universal serial bus connector is for factory adjustments and calibrations. This connec-
tor is NOT an audio input.
