MIC / LINE
1. Inputs – Connect either XLR or ¼" cables to the inputs.
2. Inserts – Place additional equipment (like compressors,
equalizers, etc.) into your signal path using "insert" cables.
3. Mic/Line or Guitar Switch (Channels 1-2 only) – Switch
to a high-impedance circuit to record electric guitars/basses.
4. Gain Knobs – Set the preamplifier gain level.
5. Monitor Blend Knob – This knob controls the amount of
direct signal (from the analog and digital inputs) that gets
blended in to outputs 1/2. This direct signal monitoring
bypasses the computer for lag-free listening while tracking.
6. Metering Section – 5-segment "ladder" meters show the
precise digital input signal for each analog channel.
Status lights indicate Firewire connection to the computer,
current sample rate, and ADAT, S/PDIF, and MIDI activity.
Stereo output meters show the levels for outputs 1/2.
7. Phones 1&2 Volume – The IO|14/26 has two separate
headphone outputs.
8. Main Level – This knob sets the output level of channels
1/2.
9. Mic/Line or Phono Switch (IO|26 only) –If you want to
connect a turntable to your IO|26, use the RCA "phono"
inputs (on the rear of the unit) and engage this switch.
10. Phantom Power – These switches let you supply +48v
"Phantom Power" to condenser microphones that require
power. Each button engages/disengages phantom power for
a pair of inputs (i.e., channels 1-2, 3-4, 5-6, and 7-8).
