Digital Output Option - Focusrite VoiceMaster Pro Mode D'emploi

- This controls the level of the FX RETURN input on the
FX LEVEL (knob)
rear panel. For example, reverb could be applied from an external processor using the
(mono) FX SEND and (stereo) FX RETURN connectors, so that a vocalist can hear
his/her vocal with reverb whilst recording.
- This controls the mix sent to the HEADPHONE
HEADPHONE MIX (knob)
output, and allows you to mix between VOICE & FX (a combination of the signal
sent to the main output plus the FX RETURN signal, as controlled by the FX
LEVEL knob) and MONITOR (the signal from the EXT MONITOR INPUTS).
HEADPHONE LEVEL (knob and TRS jack socket)
controls the level sent to the stereo HEADPHONE jack.
EXT MONITOR INPUTS (rear fascia)
balanced (+4 dBu) quarter inch TRS jacks. They allow routing of your main stereo
mix outputs (e.g. from a digital recording system) to the VoiceMaster Pro's
LATENCY-FREE MONITORING section. This means that you can monitor both
the stereo mix already recorded, AND the processed signal from your VoiceMaster Pro
at the same time. (So you can leave your VoiceMaster Pro permanently rigged up in
your recording system for tracking, whilst also allowing you to monitor the output
from your main DAW (e.g. finished stereo mix with VoiceMaster Pro-processed,
recorded vocals.) See the LATENCY-FREE MONITORING section above.
MONITOR OUTPUTS (rear fascia)
balanced, (+4 dBu) quarter inch TRS jacks. They allow routing of your main stereo
mix from e.g. a digital recording system (DAW etc) to a pair of monitor speakers.
Note that these monitor outputs are separate from the headphone bus/latency-free
monitoring section, so the outputs relay only signal that is fed from the Ext. Monitor
Inputs. (The headphone bus allows monitoring of the VoiceMaster Pro-processed
signal when tracking.)

DIGITAL OUTPUT OPTION

In addition to the analogue outputs, a high quality 24 bit, 128x over-sampled digital
output may be fitted as an option, which can operate at sample frequencies of 44.1, 48,
88.2 or 96 kHz. All of the following functions are available on the rear panel when this
option is fitted:
ADC EXT INPUT (rear panel)
+22 dBfs) line level input on the rear panel allows an additional signal to be routed
through the 'spare' channel of the stereo digital output. This input always routes
external signal to the right hand channel of the A/D converter. For example, two
VoiceMaster Pro units could be used simultaneously, with a single digital output
option. The first VoiceMaster Pro unit would feed the left channel of the A/D card
installed. The second VoiceMaster Pro unit output would be connected to the ADC
EXT INPUT, and would feed the right channel of the same A/D card, allowing two
channels of A/D conversion.
- This 24 bit output is S/PDIF format on an RCA phono
S/PDIF OUTPUT
connector. If 16 bit resolution is required, the receiving device should dither the 24 bit
signal to achieve 16 bit performance.
SAMPLE FREQUENCY (switch)
sample frequencies as marked on the rear panel. The left-hand switch selects between
44.1kHz (switch in) and 48kHz (switch out), and the right hand switch doubles the
selected frequency, providing for 88.2 and 96kHz sample frequencies.
EXT WORD CLOCK INPUT
BNC connector, the VoiceMaster Pro will attempt to synchronise to it. When the unit
is correctly locked to the external clock source the ADC LOCK LED (on the front
panel) will light to indicate correct operation. (The ADC LOCK LED should light
continuously. If this flickers it indicates bad jitter on the synchronising signal, requiring
investigation of the Wordclock-generating device.)
Fitting Instructions
See the separate A/D option owner's manual for instructions on how to fit the A/D
option.
