Panel and Connector Arrangement

(2) REC VOL (Recording Volume)
Adjusts the input level from the front panel’s INPUT L and INPUT R jacks. Use the knob
to adjust the level when recording a sample, or when passing an input signal directly
through the A3000 outputs for realtime output (“A/D In” feature).
This knob does not affect the input level to the DIGITAL IN and OPTICAL IN connectors
on the optional I/O expansion board (AIEB1 board).
(3) PHONES jack
Connects to a set of stereo headphones. The PHONES jack always produces the same
signal as the STEREO OUT jacks. Note that headphone impedance should be between
16 and 150 ohms.
(4) INPUT L, INPUT R jacks
Use these jacks to input an analog signal for recording, or for realtime output (“A/D In”
feature). Use the INPUT L jack if you are supplying a monaural signal.
(5) Display
The display indicates the status and settings for the currently selected function, and
presents messages and confirmation prompts. When you are working at a parameter-
setting page, the top line of the display indicates the parameter names, while the bot-
tom line shows the current values. The names and values appear directly over the knobs
that you use to make the settings.
(6) Knob “push” lamps
The lamp above the knob lights up to indicate that the knob can be pushed to execute
some action. If the lamp is off, pushing the knob has no effect.
(7) Knobs
You use the knobs to set the various parameter values, to switch display pages, and
execute operations. In most cases you turn the knob to set a value, and push the knob to
execute an operation — for example, to start or stop recording. Knobs are numbered 1
to 5.
