Adjusting the input level

Adjusting the input level

Here’s the basic procedure for setting up an input channel to which a microphone or instrument is connected via [MIC/LINE INPUT] jack 1–8, and adjusting the input level while monitoring the signal via the stereo bus.

1 Turn down the [GAIN] knob for the [MIC/ LINE INPUT] jack to which your instrument/ mic is connected. Also lower the [STEREO] fader to the – ∞ position.

These connectors will also accept unbalanced output from instruments such as synthesizers or rhythm machines via standard mono 1/4" phone ↔ 1/4" phone jack cables.

2 Connect a microphone or instrument to the appropriate [MIC/LINE INPUT] jack.

[MIC/LINE INPUT] jacks 1–8 can be used with the following sources.

●[MIC/LINE INPUT (XLR)] jacks 1–8

These are XLR-type balanced input jacks. Use a male XLR ↔ female XLR cable to connect your micro- phone, direct box, or a guitar/bass preamp that has a balanced output jack.

•When using condenser microphones or direct boxes that require phantom power, turn on the rear-panel [CH1-4] switch which supplies phantom power to [MIC/LINE INPUT] jacks 1– 4, and/or the [CH5-8] switch which supplies phantom power to [MIC/LINE INPUT] jacks 5–8 as required.

●[MIC/LINE INPUT (TRS phone)] jacks 1–8

These are TRS-type balanced input jacks. Use a 1/4" TRS phone ↔ female XLR cable to connect your microphone, direct box, or a guitar/bass preamp that has a balanced output jack.

NOTE

•The XLR and TRS phone jacks for the same channel cannot be used simultaneously. Connecting sources to both inputs on the same channel at the same time can result in interfer- ence and a severely degraded input signal.

3 While playing the connected instrument or supplying appropriate sound to the connected microphone, rotate the corresponding [GAIN] knob clockwise to adjust the input sensitivity so that the [PEAK] indicator lights only occasionally.

HINT

•The [GAIN] knobs adjust the gain (sensitivity) of the analog input stage. In order to make recordings with the greatest dynamic range and minimum noise, set the [GAIN] knob as high as possible without causing clipping.
