The EHT Integrated Amplifier is a class-A device which runs hot after a few minutes of
service. It requires adequate ventilation for safe operation!
. Connect the amplifier to the loudspeakers.
7. Connect the amplifier to program sources and/or a phono preamplifier.
8. Connect the amplifier to the mains.
9. Power on the program sources (while the EHT Integrated is still powered off). Wait
until the warm-up process on all these components has come to an end.
10. Power on the EHT Integrated Amplifier.
11. Wait until the unit has warmed-up.
Always switch on the program sources (or phono preamplifier) first and then switch on
the EHT Integrated amplifier, observing a delay of at least 30 seconds!
Never switch a program source (or phono preamplifier) on or off while the EHT
Integrated is powered on!
12. Choose the desired program source with the input selector. Adjust the listening
loudness manually or via remote control. The minimalist volume control module
features only two pushbuttons (volume up, Lauter and volume down, Leiser) and is
powered by 2pcsxAA batteries (not delivered with the unit). The batterie
compartment is locked with a metric size 2.5 Allan screw.
When powering off the system, always switch off the EHT Integrated Amplifier first, then
switch off the other components of the system observing a delay of at least 30 seconds!
Keep the original crate and the tube protection case for later use. They have been
specifically designed for safe transport under rough conditions! Shipping the amplifier in
inadequate packaging will result in catastrophic damages of the unit!
