POWERING UP
1. Make sure that the device is plugged in to the mains and that any external (effects) devices are correctly connected and
operation-ready.
2. Connect your bass to the QUADRUPLET'S INPUT using a shielded line cable.
3. Turn on the power using the POWER switch.
4. At the conclusion of the valve(tube) warm-up phase turn the MUTE switch off
5. Use the OUTPUT controls to set the desired volume level.
6. Adjust the controls to obtain the desired sound. To get to know the fundamental sounds of the QUADRUPLET, it is advi-
sable to begin by setting all the tone controls to 12 o'clock, before using the QUADRUMATIX switch to adjust each of
the four fundamental sounds in turn.
7. Set the correct levels of the power or bass amplifier using the OUTPUT control and the Input controls of the power
amplifier (or Gain control of the bass amp). It is advisable to begin by turning the OUTPUT control all the way to the
right before adjusting the Input control(s) of the power amplifier/bass amp. Once you have done this, you can reduce
the volume to the desired level by turning the OUTPUT control as far as necessary to the left again. This avoids the risk
that you might later overload the power amplifier by turning the OUTPUT control too far to the right.
Please note that...
- the tolerances of the counter-rotating potentiometers of the CRUNCH control can result in trivial level variations at the
DI OUT socket.
- when the unit is connected to a power amplifier, the LINE LEVEL switch on the rear panel should be depressed, but not
when the unit is connected between a bass and a bass amplifier. When the unit is operating at Instrument level, avoid
the use of over-long cables as these lead to signal loss (high ohm signal).
