iTube 302 Valve Amplifi er
• Before connecting anything to or from your iTube
302, switch OFF the power to the iTube and to the
components you want to connect.
• Make sure that all connections between the iTube
and other components are made correctly, so
L(left) goes to L, R(Right) to R, + to + and - to -.
Don’t forget to refer to the owner’s manual of each
component that you want to connect.
• Always turn OFF the power switches when you’re
connecting or disconnecting from the mains.
• Disconnect the power supply from the mains if
you’re not planning to use your iTube 302 for a
while eg holidays.
• Any speakers you connect should have an
impedance of 4-8 ohms – if it’s not written on the
back of the speaker, check with the manufacturer.
Amplifier Connections
• Connect to your speakers using high quality, bare
(stripped) speaker wire. If your speaker wires are
not connected properly you may hear no sound at
all, or if the wires are mixed up, it will sound weird
with a disturbing loss of bass.
• When using bare speaker wires, fit at least 1.6mm
of insulation inside the speaker terminals so that
there’s no bare wire showing.
• Make sure the wire holders are firmly screwed in to
stop the wires from becoming loose. If wires touch, the
speakers or the unit could be damaged. That’s bad.
