Operator`s manual

Standby is set to (that is, the power amp is active) if you want this preset to disable
and enable the power amp so the speaker renders your sound. If the
Standby switch is set to during programming, the amp will be muted when you select
this MIDI presets precisely because the function was enabled during
programming. Therefore the power amp will not boost the signal and the sound will
not be audible over the speaker.
Do not engage the Standby switch when copying with the Write/Copy (35) button, as
this launches a write operation. The control system treats the Standby switch much like
a function button. If you use it to edit the stored settings, the Status LED will flash.
To learn more about this, see section 35 and
in the appendix on page 23.
If the amp is in Standby mode, deactivating the Amp Mute function via the Amp Mute
Z-9 command will not activate it. The same goes for sending MIDI controller #7
commands and selecting MIDI presets programmed with deactivated. You
must first flip the Standby switch.
On the one hand, the amp's surveillance system monitors if speaker cords are plugged
into (57, 58), (59, 60), and (61). If none
of these ports is in use, flipping the Standby switch will not activate the power amp.
This ensures the amp is not operated without a connected load.
In addition, an electronic surveillance system monitors the power tubes. The Status
LED flashes to alert you to a defective power tube, blinking in different patterns to
identify the given tube. Specifically, it lights up briefly at regular intervals - once for V1,
twice for V2, thrice for V3, and four times for V4, five times for V5 and six times for V6
(V5, V6: Invader 150 amp). Because the tube monitoring system only works when the
power tubes are up and running, this indicator is not enabled until you activate the
power amp by flipping the Standby switch. To reset the power tube monitoring
circuitry, press the standby switch briefly.
I suggest you get into the habit of using standby during short breaks. In this mode,
current is not piped through the power tubes, so they don't get as hot (due to the lack
of anode dissipation) and are spared considerable wear. The amp is ready to run when
you flip the Standby switch because the tubes are already warm and don't require time
to heat up. For breaks of 30 minutes and longer, I recommend that you switch the amp
off in order to conserve energy.

If the amp is powered
up and the Standby switch is set to On, the Standby circuit is deactivated internally
and the Status LED shows this by flashing rapidly.
