analog outputs 1-8.
Instrument Options
Drive activates 25 dB additional gain
for maximum sustain and brute
distortion.
Lim. activates a soft-limiter with a
threshold of –10 dBFS. Note: The
Limiter can only be switched off with
input selection Front.
Speaker Emulation removes low fre-
quency noise and cuts off higher fre-
quencies.
Phantom Power
Phantom power (48V) can be selected
for each microphone input separately.
SPDIF In
Defines the input for the SPDIF signal.
'Coaxial' relates to the RCA socket,
'ADAT2' to the second 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 29.2.
SPDIF Freq.
Displays the sample rate of the SPDIF (or AES) input signal.
Word Clock
The word clock output signal usually equals the current sample rate. Selecting 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.
