MOTU FIREWIRE CONTROL PANEL (MAC OS 9)

At the 4x sample rates (176.4 and 192kHz), the

headphone output can be assigned to any analog

output pair or the Phones setting, as described

above. But at the 4x sample rates, the Phones

output is not available as an output destination for

software on the computer. Instead, it is only

available as a destination for the two CueMix DSP

mixes. In other words, it can only take CueMix

inputs.

Sample Rate Conversion

This option lets you control AES/EBU sample rate

conversion. Sample rate conversion is available

when the 896HD is operating at the 1x sample rates

(44.1 and 48kHz) or the 2x sample rates (88.2 or

96kHz). AES/EBU is disabled entirely at the 4x

samples rates (176.4 and 192kHz). Each option is

explained below.

None

No sample rate conversion occurs. Both the AES/

EBU input and output match the sample rate of the

896HD’s system clock.

AES In

The AES/EBU input locks to the sample rate of the

input signal (whatever it happens to be) and

converts it to the 896HD system clock rate. The

Rate Conversion LEDs on the 896HD front panel

indicate the incoming sample rate and that rate

conversion is occurring.

AES Out slave to AES in

To m a ke t h e AES/EBU output sample rate match

the sample rate currently being received by the

896HD’s AES/EBU input, choose AES Out slave to

AES in. This setting requires a connection to the

896HD’s AES/EBU input from a device that is

transmitting an AES/EBU clock signal.

☛ Be careful when both the 896HD’s AES/EBU

input and output are connected to the same

external device: this option is likely to create a

clock loop.

☛ When you are using the AES/EBU input as a

clock source for sample rate conversion on the

AES/EBU output, you cannot use the AES/EBU

input for audio input.

AES Out x 2 / AES Out ÷ 2

Choose one of these sample rates when the desired

AES/EBU output rate needs to be twice the 896HD

system clock rate (when the system clock is at

either 44.1 or 48 kHz) or half the system clock rate

(when the system clock is at 88.2 or 96 kHz). Either

way, the AES/EBU output remains resolved to the

896HD system clock. For further details about this

option, see “Syncing AES/EBU devices” on

page 26.

Programmable Meters

This option lets you choose which bank you wish

to monitor with the eight programmable meters on

the MOTU 896HD front panel. Your choices are:

Analog Out, ADAT In or ADAT Out.

AES/EBU Meters

This option lets you choose to monitor either AES/

EBU input or output with the programmable AES/

EBU meters on the MOTU 896HD front panel.

Clip Hold Time

The Clip Hold Time option controls how long the

top red LED remains illuminated after clipping

occurs (see Figure 6-2 below).

Figure 6-2: The Clip Hold Time option.

If you want the ability to clear the LED manually

from your host audio software or the Cue Mix

Console, Choose Inﬁnite from the Clip Hold Time

menu. In Digital Performer or AudioDesk, you can

clear the 896HD clip LEDs by choosing Audio

menu>Clear All Clipping Indicators.

The ‘Clip Hold Time’ option controls

how long this LED remains illuminated.

This LED lights up momentarily.
