other designs Class A while avoiding the problems of
distortion in Class B.
The innovative design of ACRH-2.6 complements metal
film resistors and printed circuit silver coating.
Connections
All inputs and outputs of the preamplifier are unbalanced
RCA connectors.
The back panel is organized by blocks from left to right
(for this explanation see figure 1): the first RCA block
contains the inlets to the amplifier (1), the second is for
the preamp (2), the third has four inputs, which have the
same gain and impedance (3); the fourth section is the
input of the basic high quality phono stage for a turntable
(4); and the last one is the direct output avoiding the
volume control, so you can use the ACRH-2.6 together
with a 5 channel preamplifier for a high end multichannel,
it can also be used as an input and output circuit for a
processor (5).
The preamplifier has two outputs per channel, they are
connected in parallel. One will be connected to the
amplifier input, completing the integrated system. The
other is available to connect an active subwoofer or
perhaps an adapter multi-room extension or surround
system (6).
To wire the speakers, connect the 5 ways binding post of
the amplifier terminals to corresponding speaker, use a
good cable with a 12 gage or more. It is recommendable
to avoid long runs, less than 10 meters.
Connect the speakers red to the red and the black to the
black (7), it is VERY important to avoid any short circuit,
this will lower the life expectancy of the ACRH-2.6.
The output stage has big current capability and it is
protected by fuses, if a fuse blows, it might be because
the ACRH-2.6 was overdriven or the speaker cable has a
short circuit.
Check for proper connections before turning the ACRH-
2.6 on, for this see figure 2.
The minimum loudspeaker impedance is 4 Ohms, avoid
paralleling speakers that can lower the speakers below
this recommended impedance.
When the power line is connected to the AC wall outlet
the filaments of the tubes and the remote control receiver
will be turned on.
The filament will be on as long as the AC is connected,
so the unit will be in standby mode, and can be turned on
and use immediately, also the life expectancy of the
tubes will be longer.
IMPORTANT: Avoid turning the unit on immediately after
you connect the ACRH-2.6 to the wall outlet, let it warm
the filaments for a couple of minutes.
