5. AC mains connection
The IEC power inlet and mains fuse holder are located on the left side toward the front and on the belly of
the machine. Disconnect the amplifier from the AC plug if you have to replace the fuse. Internal rail volt-
ages of 230 volts can cause serious electric shock.
6. Component connections
Before initial power-up, install the interconnects to the preamplifier and the cables to your loudspeakers. If
possible, connect the included ground wire between the grounding posts of your preamp and amplifier.
Interconnects
Use any high-quality RCA or XLR-terminated cable. Insure good non-oxidized contacts. Naturally, we rec-
ommend our own NF/XLR cable which has been designed for optimum synergy. Because The Light in the
Dark operates fully differential from input to output, XLR connections from the preamp are the preferred
means for optimal results, especially when that preamp happens to be our fully differential, fully balanced
(and fully complementary) The Tube valved linestage!
Loudspeaker cables
Insist on cables with superior non-oxidized contacts and sufficient conductor mass to supply adequate cur-
rent to the speakers. This insures proper damping factor for mandatory transducer control. (Cables of in-
sufficient conductor mass can strangulate an amplifier's current delivery.)
7. Power mains
To turn the machine on or off, rotate the left frontal control. Three blue LEDs inside the central display will
confirm power as will the glow of the valves. Thermal stabilization and final readiness are indicated after
about 2-3 minutes once the two outer LEDs have extinguished. Should one or both of these outer indica-
tors remain lit, contact your dealer or the factory to avoid internal damage. Optimal operation conditions
and stabilized sonics for The Light in the Dark are reached within a half hour of turn-on.
If there is a problem with the amplifier, either both or one or the other LED will remain lit, at which point
you should turn the amplifier off and contact your dealer / distributor or EINSTEIN directly. The unit will
achieve its optimal sound and operating temperature after approximately half an hour. It is recommended
that you don't tax the amplifiers unnecessarily during this warm up phase as it may result in lower tube
life.
