FREQUENTLY ASKED QUESTIONS
Q: Should I use balanced connectors with my OctoPre?
A: Preferably yes; the Line level analogue inputs and outputs are balanced, operating at
+4dBu. If you wish to connect unbalanced equipment to the OctoPre LE’s Line inputs
however, this can be done, but the signal level will be 6dB lower. Channels 1 and 2 will
expect to receive an unbalanced signal if the INST switch on those channels is selected.
Q: Does the OctoPre LE have the same kind of spectacular bandwidth that
has given the Red and ISA range units their reputation for ‘open-ended’
sound?
A: Yes. The audio bandwidth of the OctoPre LE is 10Hz to 122kHz!
Q: Can I take my OctoPre LE with me when I travel internationally?
A: It depends. There are three versions of the OctoPre LE mains transformer. One is
suitable for use in North America and Japan, with mains voltages in the 100-120V
range. The other two versions are designed for use in the UK and Europe (the only
difference being the mains plug), with mains voltages in the 200-240V range. If you
buy an OctoPre LE in a particular territory, it will be configured for ONLY that
territory’s mains voltage range. For example, if you’re travelling from the USA to the
UK, you CANNOT use your US model OctoPre LE with the supplied mains
transformer. But if the mains voltage in the country you’re visiting is in the same
range, you can use the OctoPre LE with no problems - so taking an OctoPre LE from
the USA to Japan, or from Germany to France, for example, would be fine. An
external supply for different territories is available from your local Focusrite distributor.
Q: Can I retrofit a digital board to an analogue OctoPre LE at a later date?
A: Yes, and you can do it yourself - it can easily be retro-fitted by the customer
without any soldering etc, just a few screws to undo and three clip-connectors to join to
the main PCB.
