Rear Panel Connections; Getting Started - Focusrite TwinTrak Pro Mode D'emploi

REAR PANEL CONNECTIONS

CHANNEL 1 (L) and CHANNEL 2 (R)
dBu) TRS jack LINE INPUT connector on the rear panel, with balanced XLR MIC
INPUT and unbalanced 1/4" jack INSTRUMENT INPUT connectors located on
the front fascia. The TRS jack INSERT connectors on the rear panel allow an
additional processor to be inserted into the signal chain between the pre-amps and the
other processing sections of the unit. OUTPUTS are provided on both balanced (+4
dBu) XLR and unbalanced (-10 dBV) 1/4" jack connectors. There is also a TRS jack
COMPRESSOR SIDE-CHAIN INSERT connector – see page 6 for details.
- The balanced (+4 dBu) TRS jack FX SEND and FX RETURN connectors
FX
allow effects units to be used in the monitor section without affecting what is being
recorded. See LATENCY-FREE MONITORING and MONITOR LEVELS on
page 7 for further details.
LATENCY-FREE MONITORING
MONITOR INPUT connectors allow the output of a stereo mixer or sound card to
be connected to the TwinTrak Pro's LATENCY-FREE MONITORING system.
There are also balanced (+4 dBu) TRS jack HEADPHONES MIX connectors and
balanced (+4 dBu) XLR MONITOR OUTPUT connectors, allowing the TwinTrak
Pro to be connected to an external monitoring system. See LATENCY-FREE
MONITORING CONNECTIONS on page 8 for further details.
- The co-axial (RCA phono) S/PDIF connector allows a digital
DAC INPUT
signal to be fed to either the monitoring section, or to the line input for further
processing. This section also features a BNC wordclock out connector. See DIGITAL
CONNECTIONS on page 9 for further details.
- An optional ADC is available and can be retrofitted at any time.
ADC OUTPUT
This provides an S/PDIF output as well as a BNC wordclock in connection. See
DIGITAL OUTPUT OPTION on page 9 for further details.
- Each channel has a balanced (+4
- The balanced (+4 dBu) TRS jack

GETTING STARTED

1. Ensure that nothing other than the mains supply is connected to your TwinTrak
Pro, then switch it on via the POWER switch on the right hand side of the unit. If
your unit is permanently connected to a patchbay, ensure audio is not being fed to any
connected speakers, thus avoiding any 'turn-on' speaker pops.
2. Connect the appropriate OUTPUTS (either +4 dBu balanced XLR or –10 dBV
unbalanced jack) from both channels on the rear panel of the TwinTrak Pro to your
recorder or audio interface. If using the digital output option, connect the digital
output to the digital input of your recorder or audio interface. See page 9 for more
information on the TwinTrak Pro digital output option. If using your digital input,
connect the digital input to the digital output of your recorder or audio interface.
3. Connect the MONITOR inputs to your desk or sound card output and connect
the MONITOR outputs to your monitor amplifier inputs or external powered
monitor speakers.
4. Ensure that each processing section is switched out (IN switch disengaged and
unlit).
5. Connect your input sources as required. Microphones can be plugged into the XLR
MIC INPUTs on the front fascia. If you wish to connect a line-level source (to use the
TwinTrak Pro's dynamics processing when mixing down, for example) connect this to
the TRS LINE INPUTs on the rear panel. Alternatively, you may connect electric
guitars or similar instruments to the INSTRUMENT INPUTs via the unbalanced
1/4" jack inputs on the front fascia. Be sure to select the right gain option (HIGH
GAIN switched in for instruments that require extra gain, such as passive instruments)
- see page 5 for more on the HIGH GAIN setting.
6. Check that the correct input is selected in the DISCRETE CLASS A PRE-AMP
section. If recording a line level source connected to the rear panel LINE INPUT,
ensure the LINE switch is engaged. If recording an instrument through the front
INSTRUMENT INPUT, ensure the INST switch is engaged. The MIC LED will
illuminate if neither the INST or LINE switches are engaged. The MIC input is then
automatically selected.
7. Make sure the phase reverse (Ø) and HPF ( ) switches are disengaged and that the
LEVEL control is fully counter-clockwise.
8. If using a condenser or dynamic microphone that requires phantom power, engage
the +48V switch. If you are unsure whether your microphone requires this phantom
power, refer to its user guide. Phantom power can damage some microphones,
especially ribbon microphones, so beware.
