Amplifier control
A. Turning on the amplifier
Before turning on
check
, if speaker is connected to the right output
connector
(n.27, n.28 or n.29
) according to the impedance of
used speaker (cabinet). All switches on the front panel trigger down
and fade out both volume controls
n.8 and n.12
.
Connect the enclosed line cable to connector
n.17 (Mains)
and
check if the right mains grid (US/EU) is set on the switch
n.18 (EU-230VAC, US-110VAC)
and then connect the power
plug to the mains socket. Turn on the device with POWER switch
(n.1)
.
Red control light STANDBY starts flashing with 1 second
interval, what means that tubes are warming up and amplifier is
getting ready. After the light is stable (approx. 1min) you can turn
on the output of the amplifier by switching the STANDBY trigger
n.2 to the higher position.
You can extend the life of your vacuum tubes by using
STANDBY switch if you turn on the STANDBY mode during the
break
1
(up to 30mins).
B. Best settings
There is no such thing as best settings, because every each
human ear/brain is unique and hears sounds differently. We set
the controls to have wide range so that you can find the best sound
for your hearing apparatus.

It is not recommened in common to operate amplifier with tubes
heated up
in
STANDBY mode
longer than 30 minutes (red LED
flashing) because of bad influence on life of vacuum tubes (cathode
poisoning might happen).
