When the METERS light is illuminated (on the right), this section of LEDs provides metering for 2408mk3’s analog input and output activity. Each channel has a 5-segment column of LEDs measuring -42 dB to 0 dB. When the METERS light is not illuminated, The LEDs in this section indicate the CLOCK, SOURCE, and BOUNCE settings in the 2408mk3. When the 2408mk3 is under control of the PCI-424 card (and the host computer), you cannot change the settings using the SELECT and SET buttons, as they are under control of software running on the computer. The only thing you can do in this mode is press the SELECT button to switch between the clock status display and analog metering.
When the 2408mk3 is not under PCI control (no 2408mk3- compatible software is running, or the computer is turned off), the 2408mk3 operates as a stand-alone format converter, and you can use the SELECT and SET buttons to change the CLOCK, SOURCE, and BOUNCE settings.

Bounce When the 2408mk3 is operating as a stand- alone format converter (no 2408mk3- compatible software is running on the computer or the computer is turned off), the BOUNCE setting lets you shift tracks during a transfer. Use the SELECT button to activate (illuminate) the BOUNCE LED. Press the SET button repeatedly to make the desired bounce setting. Your choices are:
■ No shifting
(1-2)
■ Shift all tracks down by two
(3-4)
■ Shift all tracks down by four
(5-6)
■ Shift all tracks down by six
(7-8)
Tracks that are shifted lower than track 1 wrap around to track 8 and shift down from there. The “Swap L to R” option swaps the channels in each pair, in addition to the amount they are shifted. This allows you to copy any source track to any destination track. For example, you can copy track 4 to track 1 by choosing “3-4” and “Swap L to R”.
This is a standard quarter- inch stereo headphone jack. Its output matches analog outputs 1 and 2, but the volume knob to the right controls the headphone output only.
Source When the 2408mk3 is operating as a stand-alone format converter (no 2408mk3-compatible software is running on the computer or the computer is turned off), the Source setting determines which audio format (ADAT, Tascam, Analog or SPDIF) will be the source of the transfer. Use the SELECT button to activate (illuminate) the SOURCE LED. Press the SET button repeatedly to make the desired source setting. Your choices are:
■ Analog (all inputs at +4) ■ Analog (all inputs at -10) ■ Analog (mixed input levels) ■ The stereo SPDIF input ■ ADAT Bank A ■ ADAT Bank B ■ ADAT Bank C ■ ADAT banks A, B and C ■ Tascam (with the same bank
choices as shown above for ADAT)
The setting for Analog with mixed input levels uses the input level settings you’ve specified with the MOTU PCI Audio Console (by clicking the Interface Options button).
Internally, the 2408mk3 is divided into three banks of I/O: Banks A, B and C. This section of the 2408mk3’s front panel shows you the input and output activity for each bank if it has been assigned to either the ADAT, Tascam or SPDIF digital I/O formats. When you are operating the 2408mk3 under computer control, the 2408mk3 always outputs to both ADAT and Tascam, regardless of which one you have chosen in AudioDesk or the PCI-424 configuration software. The top (orange) row of lights show input activity for each channel in the bank, and the bottom (green) lights show output. At 88.2 or 96 kHz, TDIF and ADAT optical support 4 channels per bank.
Clock When the 2408mk3 is operating as a stand-alone format converter (no 2408mk3-compatible software is running on the computer or the computer is turned off), the CLOCK setting
determines what digital clock the 2408mk3 is slaving to. The choices are:
■ 44 / 48 / 88 / 96 - These four LEDs indicate the sample
rate. If the 2408mk3 is set to slave from an external source, and no clock source is present, these lights blink to show that the 2408mk3 does not currently detect a clock signal. If the 2408mk3 is running under its internal clock, use the SET button to choose the desired sample rate.
■ Int (Internal) - Means that the 2408mk3 is running under
its own internal clock.
■ PCI - This LED means that the 2408mk3 is slaved to the
PCI-424 card. This light is not available when the 2408mk3 is in stand-alone mode.
■ Dig (Digital input) - This option refers to the digital I/O
format being recorded. For example, if you are converting from ADAT to Tascam, and you have selected ADAT as the source, the 2408mk3 will slave to the clock supplied by the ADAT optical digital input.
■ Word - the 2408mk3 is slaved to its word clock input. ■ Vid (video) - the 2408mk3 is slaved to a video signal
received on its VIDEO IN (BNC) connector.
■ LTC (Longitudinal Time Code) - the 2408mk3 is slaved to
SMPTE time code on an analog input.
You can use the SET button
only when the 2408mk3 is operating as a stand-alone format converter (no 2408mk3-compatible software is running on the computer or the computer is turned off). When the 2408mk3 is in stand-alone operation, press the SET button repeatedly to cycle through the current CLOCK, SOURCE or BOUNCE settings, which control what the 2408mk3 will do as a format converter.
When the 2408mk3 is in stand-alone operation, press the SELECT button repeatedly to illuminate the desired CLOCK, SOURCE or BOUNCE LED. Then press the SET button repeatedly to make the desired setting. When the 2408mk3 is under control of the computer, press the SELECT button to toggle between the clock display and analog metering in the ANALOG OUT section of the front panel.
When these three lights are illuminated, they indicate that the 2408mk3 is operat- ing under control of the PCI-424 card. They also indicate that the LEDs in the ANALOG OUT section are displaying the 2408mk3’s current clock settings (as you have chosen in the PCI Audio Console software). Press the Select button to toggle the ANALOG OUT section between this clock display and analog output metering.
This knob controls the volume of the headphone output.
This knob controls the volume of the main outs on the rear panel.
When the 2408mk3 is resolving to video or SMPTE time code, the LOCK light glows green when lockup has been achieved. The TACH light blinks once per second when the 2408mk3 is successfully reading address (time code) information.
