PERFORMANCE TIPS & TROUBLESHOOTING

up conﬁgured to record from their analog inputs.

You won't be able to record from the MOTU 896 to

a tape deck until it is switched to digital input.

Alesis blackface (classic) ADAT optical sync

If you are using a Classic (black-faced) ADAT as a

sync master in your MOTU 896 setup, and you

want to record sample accurately into it, you must

conﬁgure it to use its internal clock, instead of

slaving to the optical input. To do this, hold down

the SET LOCATE button and press the DIGITAL

IN button. This will toggle the ADAT between

external sync (shown as "diG") and internal sync

("int"). Note that the ADAT will return to the "diG"

setting each time it is powered off.

Alesis ADAT track offset

If you ﬁnd that sample accurate transfers from an

ADAT are displaced by a small amount, try to reset

the ADAT to its factory default state. This is

accomplished by powering on the ADAT while

holding down the RECORD and PLAY keys simul-

taneously. The ADAT lx uses a 'soft' power key so lx

users will have to unplug and plug the ADAT lx

while holding down the RECORD and PLAY keys.

Clicks and pops under word clock sync

Many problems result from incorrect word

clocking. It is essential that all digital devices in the

system be word locked. Consult chapter , “Making

sync connections” (page 21) for detailed

information on how to word clock your gear.

Whenever there is any weird noise or distortion,

suspect incorrect word lock.

Clicks and pops under ADAT Sync

Sometimes, the ADAT sync cable seems to be

plugged into the MOTU 896, and partially works -

but it isn’t really all the way in. This can cause clicks

when slaved to ADAT 9-pin. Make sure the cable is

seated ﬁrmly.

Clicks and pops due to hard drive problems

If you have checked your clock settings sync cable

connections and you are still getting clicks and

pops in your audio, you may have a drive related

problem. Set the MOTU 896 Clock Source to

Internal and try recording just using the analog

inputs and outputs of the MOTU 896. If you

encounter the same artifacts you may want try

using another drive in your computer. Clicks and

pops can also occur when the drive is severely

fragmented, the disk drivers are outdated, or if you

are using a SCSI accelerator that is not optimally

conﬁgured for working with audio.

Connecting or powering gear during operation

It is not recommended that you connect/

disconnect, or power on/off devices connected to

the MOTU 896 while recording or playing back

audio. Doing so may cause a brief glitch in the

audio.

Monitoring - How to monitor inputs?

Please refer to the documentation for the audio

application that you are using. If your application

does not support input monitoring, you will need

to use the MOTU 896’s hardware-based CueMix

Plus monitoring feature. Please see “Monitor input

— CueMix™ Plus” on page 39.

No optical inputs or outputs are available in host

audio application

Check to make sure you have the desired optical

inputs and/or outputs enabled in the MOTU

FireWire Audio Console.

Controlling monitoring latency

See “Monitoring live input” on page 41.
