8) Attach Power Cord - Connect the IEC end of detachable power
cord to the amplifier, and plug opposite end into corresponding
outlet. See Figure 4.
10) Connections to other components -. The input connections from
the preamplifier are made via RCA jacks on the rear of the
amplifier. Be sure to use high quality interconnect cables - they
do make a difference. See figure 4.
11) Polarity - The Rogue M-120 amplifier is a non-inverting
amplifier (positive signal in gives positive signal out) so, for best
sound, care should be taken to ensure correct polarity at the
speaker terminals. If your preamplifier is also non-inverting, then
connect the positive (+) outputs of your power amplifier to the
positive (+) terminals of the loudspeakers and the negative (-)
outputs to the (-) negative loudspeaker terminals. If your
preamplifier is inverting, then connect the positive outputs (+) of
you power amplifier to the negative (-) loudspeaker terminals,
and the negative outputs (-) to the positive (+) loudspeaker
terminals. If you are unsure whether your preamplifier is
inverting, check the owners manual or contact the manufacturer.
If all else fails, try both connections and listen to which sounds
better (do this using several different recordings as not all
recordings are made with correct phase).
9) Amplifier Location - The Rogue M-120 amplifier is an open tube
design and is designed such that natural convection flow patterns
provide cooling as required. This cooling has been designed and
tested to ensure long term reliability and safety. Therefore, to
ensure proper cooling, the unit should be located in a position so
that these air flows are not impeded. Since there are vents on the
bottom of the unit, it should always rest on a firm surface to
ensure adequate spacing between the resting surface and bottom
of unit.
WARNING - To ensure proper cooling, the amplifier
should not rest on carpet or other soft surface. In addition,
the unit should not be set in an enclosed shelf, and should
have a minimum of 6 inches of free space on all sides.
Failure to allow proper spacing will cause the unit to
overheat.
