4. Turn OFF procedure
● Always turn down the volume to minimum first.
When powering down your system, always turn the amplifier off first. The unit can be turned off at
any time. Important: If the amplifier was turned OFF even for a short period of time, you have to
wait at least 2 minutes before turning it back ON. Do not turn it ON then OFF and then ON again in
quick succession. This precaution will minimize the stress (high voltages) on internal components.
Note: during these 2 minutes "waiting time" in addition an electronic timer prevents the untimely
power-on of the amplifier.
At switching off a short „plop/pop“ (discharge of a capacitor or click of a relay) may be heard as
we did not install output relays at the speaker terminals influencing the sound quality.
These peculiarities are perfectly normal.
Always switch amplifiers off and wait 2 minutes before connecting or disconnecting any leads.
The amplifier is equipped with a two step release delay circuit. When you power off the amp it
takes approximately 40 second time until it’s completely turned off.
Meanwhile the protection circuit is activated (disruption), a short but intense switching noise of the
relay will be heard from the speakers (the B+ relay under charge disconnects the high voltage of
the power tubes). This is no reason for concern but completely normal.
Bottom plate
Note: The power switch (on/off) is located at the front left corner of the bottom plate!
To switch on or off always use the power switch of the equipment!
Never remove the bottom plate of the Vulcan before unplugging the unit from the wall!
