The AUDIO OUT is a standard stereo phone jack, but it accepts a stereo or mono plug. For
single-channel use with instrument amplifiers, a mono cable with mono plugs at both ends
should suffice. For playing through both channels of a stereo amplifier, you will probably
need a stereo cable with a stereo phone plug at one end and two phono plugs at the other.
These will connect to the amplifier AUX or TAPE inputs. (To protect speakers, it is customary
to switch off the amplifier when making these connections.)
A 6.35mm line out is also provided at the rear panel, this is more typically used to connect
audio interfaces, PA systems etc.
Stereo headphones can be plugged directly into the AUDIO OUT jack. The headphones
should have a minimum impedance of 600 Ohms.
When power and audio output connections have been made, first switch Pro-1 power on with
back panel switch sited next to the DC input jack socket, then switch amplifier power on. If
you think the Pro-1 may not be operating, see the section titled “In Case Of Difficulty” in this
guide.
For other back panel connections, see the appropriate section later in this guide.
