GETTING STARTED – A QUICK GUIDE
1. Ensure that nothing other than the mains supply is connected to your OctoPre LE,
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 to avoid any turn-on speaker pops.
2. Connect the analogue line outputs of the OctoPre LE to your recorder or audio
interface. If using the digital converter option, connect the OctoPre LE's ADAT
output to the ADAT input of your recorder or audio interface. See page 4 for more
information on the OctoPre LE digital options.
3. Ensure that each channel's LEVEL is set fully anti-clockwise.
4. Connect your input sources to the eight channel inputs as required. Microphones
should be plugged into the XLR MIC INPUTS on the rear panel. If you wish to
connect line-level sources, connect these to the LINE INPUTS on the front panel; this
will automatically switch off the corresponding microphone inputs. You may connect
an electric guitar or bass to the Line inputs on channels 1 and 2.
5. If using the INSTRUMENT INPUT on channel 1 or 2, ensure that the
corresponding INST switch is engaged. If using a MICROPHONE (XLR) INPUT
on the rear panel, ensure that nothing is connected to the corresponding LINE INPUT
on the front panel.
6. If using one or a number of condenser microphones that require phantom power,
activate the 48V 'All On' switch on the front panel. This will provide phantom power
to ALL microphones connected to the rear panel MIC INPUTS. If you are unsure as to
whether your microphone requires phantom power, refer to its user guide, as phantom
power will damage some microphones, most notably ribbon microphones or radio mic
receivers. NB Dynamic microphones will be unaffected by phantom power.
7. Increase the LEVEL control for each channel you wish to use, ensuring that the red
O/L LED does not illuminate. To visually monitor the incoming signal on a particular
channel, press the source switch beside the dBFS meter until the desired channel's O/L
LED is lit (See METERING section below). It is advisable to set the incoming signal
to be an average of between -10 and -6dBFS.
8. If using microphones, ensure that the microphone placement is at its best. Before
you start recording, alter the microphone placement until you get as close as possible to
the sound you want. Note that moving the microphone may have an effect on the level
of the signal entering the OctoPre LE, requiring an alteration to the LEVEL setting.

FACILITIES AND CONTROLS

POWER
This switch turns the unit on. We recommend that the unit be powered up before
connecting to any equipment that it is feeding, to avoid clicks or thumps, which may
harm output devices. It is also a good idea to allow the unit to stabilise for a couple of
minutes before use to ensure that the internal circuitry is properly acclimatized.

LINE INPUTS

Line (and instrument for channels 1 and 2) inputs are provided on the front panel for all
eight channels via balanced 1/4" jack sockets. An unbalanced signal will be accepted for
all channels and expected for channels 1 and 2 when in instrument mode. Connecting a
jack plug into a front panel line input automatically cuts the corresponding mic XLR
input on the rear panel and selects an appropriate gain calibration for the level dial on
that channel.
INST (Switch) [CHANNELS 1 & 2 ONLY]
When engaged (in), the corresponding 1/4" jack front panel (line) input will accept an
unbalanced instrument signal and the gain dial for that channel will be calibrated to an
appropriate level.
