2 and 3. The output is XLRM-type balanced, non-inverting. AT-MX341a mixers can be daisy-chained via the included AT8325/1.0 Link Cable and special connectors on the rear panel. The control bus and the audio are carried between mixers by the link cable. -

(This control does not affect the meter indication.) 8. Master Threshold / Manual control. Sets the reference level that must be exceeded for a microphone to be considered “in use.” Adjust to keep background noise level from triggering microphones. “Manual” setting bypasses all of the SmartMixer’s automatic functions. -

4. Output. Balanced line-level output. Can be changed to mic-level output via internal switch (see page 7). XLRM-type connector. 5. Inputs. Balanced microphone inputs for low impedance dynamic or condenser mics. Can be changed to line-level inputs via internal switches (see page 7). XLRF-type connectors. -

5. Turn Power switch “on.” The mixer will perform a self-test and turn each microphone “on” and “off ” consecutively. 6. Connect a microphone to Input 1 and turn the Gain 1 control to the “nine o’clock” position. The channel 1 LED will light if the microphone is operational. -

The switching is so fast and silent that the meeting can still be completely interactive. Mode 3…One Priority Pre-select switch Up The selected priority microphone can come on at any time and can override any other mic that is on (popularly called “The Chairperson” mode). -

In instances when the number of microphones in use is high, it may be necessary to increase the amount of “off ” attenuation per microphone to keep the total ambient noise level low. There are “off ” attenuation adjustments inside the unit. To adjust the “off ” attenuation of channel 1, unplug the unit, remove the top cover and locate the trimpot designated on the circuit board by “VR5”... -
Page 9: Control Voltage Out
Control Voltage Out When a microphone channel turns “on,” as indicated by a Selected Channel LED on the front panel, the channel’s associated Control Voltage Out goes “high” (+4 VDC). This signal can be used to light indicator lamps, switch speaker zones on and off, select video cameras, etc. The control voltage should not be connected directly to an inductive load such as a relay coil, as damage to the mixer may result. -

The combined output is then taken from the last mixer in the chain. Because lockout information is passed between mixers through Link In/Out, the last-microphone-on condition is not violated. Thus only one microphone per installation will stay on when no one is speaking. -
