Buffer Size
The setting Buffer Size determines the
latency between incoming and outgo-
ing ASIO and GSIF data, as well as
affecting system stability (see chapter
11). Under Windows MME this setting
determines the DMA buffer size (see
chapter 9.4).
Inputs
Input selection for the channels 1, 7
and 8. Channel 1 can be the front In-
strument input, or the rear TRS jack, or
both simultaneously. Channel 7/8 can
be the front microphone input, or the
rear TRS jack, or both simultaneously.
Word Clock Out
The word clock output signal usually
equals the current sample rate. Select-
ing Single Speed causes the output
signal to always stay within the range
of 32 kHz to 48 kHz. So at 96 kHz and
192 kHz sample rate, the output word
clock is 48 kHz.
SPDIF In
Defines the input for the SPDIF signal. 'Coaxial' relates to the RCA socket, 'ADAT2' to the sec-
ond optical TOSLINK input.
SPDIF Out
The SPDIF output signal is constantly available at the phono plug. After selecting 'ADAT2' it is
also routed to the second optical TOSLINK output. For further details about the settings ‘Pro-
fessional’, ‘Emphasis’ and ‘Non-Audio’, please refer to chapter 16.2.
SPDIF Freq.
Displays the sample rate of the SPDIF (or AES) input signal.
Input Level
Defines the reference level for the rear analog inputs 1-8.
Output Level
Defines the reference level for the rear analog outputs 1-8.
Phantom Power
Phantom power (48V) can be selected for each microphone input seperately.
Instrument Options
Drive activates 25 dB additional gain for maximum sustain and brute distortion.
Speaker Emulation removes low frequency noise and cuts off higher frequencies.
