Controls and Connectors Descriptions

1.
Mic Inputs: Balanced XLR inputs featuring high-quality mic preamps. These inputs are wired in parallel with their
associated Line Inputs (2), and selected with the channel Mic/Line switches (4). To use the XLR jack as the input
source for a channel, the corresponding MIC/LINE switch will need to be in the up position. Phantom power for the
mic inputs is activated by the rear-panel switch (35).
2.
Line Inputs: Balanced/unbalanced line-level 1/4” analog inputs. Line inputs 1 through 5 are wired in parallel with
their associated MIC INPUTS (1), and selected with the channel MIC/LINE switches (4). To use the Line Input jack
as the input source for a channel, the corresponding MIC/LINE switch must be in the down position. Line inputs 5
through 8 appear as Left and Right channels of stereo inputs 5/6 and 7/8.
3.
Channel Inserts: These four 1/4” TRS jacks allow external signal processors to be inserted into the signal path of
input channels 1 through 4. The insert point is immediately after the input gain stage. The digital audio streams from
the computer routed to channels 1 through 4 will not pass through the insert jacks.
4.
Mic/Line Selector: Channels 1 through 5 each have a dedicated MIC/LINE input switch which selects between
the XLR (mic level) input (1) or the 1/4” (line-level) input (2). When the MIC/LINE switch is in the “up” position,
the XLR mic input will be selected. When the MIC/LINE switch is in the “down” position, the 1/4” line input will be
selected.
5.
Channel Input Gain: These analog level control knobs determine the input level of the corresponding channel’s
mic (XLR) or line input. The gain stage is after the Mic/Line Selector (4), therefore both the mic and line inputs will
be controlled.
NOTE: The best signal-to-noise ratios are achieved by maximizing the level of analog inputs at the A/D converters.
For best results, levels should be adjusted while paying close attention to not only to your audio software’s meters,
but also to the input channels’ PEAK LEDs (10).
6.
Channel Source Buttons: These buttons select the audio source for each channel. When the button is in the
“up” position, the analog input for the channel will be selected (as determined by the channel’s Mic/Line Selector
(4)). When the button is in the “down” position, the associated digital audio stream from the FireWire input will be
selected.
