¼" INSTRUMENT INPUT JACK
This ¼" jack accepts unbalanced, low-level, high impedance instrument sources such
as electric guitar, acoustic guitar with a pickup, and electric bass. The input gain
is adjusted using the Line 1/Inst knob on the front panel. When an instrument is
plugged into this input, it disables the Line 1 audio input on the rear panel.

LINE 1/INST
This knob adjusts the Line 1 and Instrument Input gain.
PEAK LEDS
These LEDs light when the input signal is within 5dB of analog clipping. If the Peak
LEDs flicker occasionally, the signal is approaching clipping levels, but does not neces-
sarily indicate distortion or actual clipping.

MONITOR MIx
The Alpha Studio gives you the ability to hear your analog input signals directly and
immediately while recording, without having to adjust levels in software, and before
the delay caused by digital converters and computer recording latency. This zero-laten-
cy analog monitoring is controlled by the Monitor Mix knob, which you can use to
adjust the blend between the Alpha Studio’s live analog inputs (called “Direct”) and
any audio coming back from the computer via USB (“Playback”). To adjust the play-
back mix coming back from the computer (previous tracks, effect returns etc.), use
