TRIMMING THE ANALOG INPUTS

The 896HD analog inputs provide trim knobs on

the front panel. To calibrate an audio input:

1 Record-enable a track in your host software.

2 Choose the desired 896HD input for the track.

3 Open the mixer or other window that displays

the track’s audio input level.

4 As you feed signal to the input, adjust the input’s

corresponding trim knob on the front panel of the

896HD until peaks in the level meter are as high as

possible without clipping (hitting zero dB).

PROCESSING LIVE INPUTS WITH PLUG-INS

If you patch a live input (such as a MIDI

synthesizer) through a plug-in effect in your host

software, you might hear a slight delay. There are

several ways to reduce this delay. For details, see

chapter 11, “Reducing Monitoring Latency”

(page 85).

USING A FOOT SWITCH

Use a foot switch connected to the 896HD to

trigger recording punch-in and punch-out, or any

other feature in your host audio software that is

assigned to a computer keystroke. By default, the

foot switch triggers the 3 key on the computer

keypad. To trigger a different set of keystrokes with

the foot switch, visit the MOTU FireWire Audio

Console. (See “Enable Pedal” on page 43.)

SYNCHRONIZATION

As of this writing, Mac OS X does not allow third-

party applications to take advantage of the

896HD’s sample-accurate sync features. Refer to

www.motu.com for further developments.

However, if most applications that support external

sync will be able to supports the 896HD’s word

clock sync capabilities. Consult chapter 3,

“Installing the 896HD Hardware” (page 15) and

use the synchronization diagrams in that chapter

to synchronize your software and the 896HD to the

other components of your system.
