X5 Owner’s Manual
The X Series amplifiers have the tremendous dynamic range (>150
dB) to do justice to the 24 bit recordings of the 21
st
Century. The
simple but powerful circuitry moves easily from total silence to
explosive transient and back to silence without a trace. It’s a spooky
experience.
So relax and enjoy your amplifier. Call us if you ever have a problem
or question. Thank you for buying our product.
You can position the amplifier anywhere you want, but it requires
ventilation. We do not recommend placing it in enclosed cabinets or
small closets without means for air to circulate freely. The amplifier
idles at about 200 watts.
Let’s talk about power requirements. The amplifier draws about
2 amps (continuous rms) out of the wall during normal audio
operation, and this reflects mostly the idle current that we run
through the output stage. If you are driving a low impedance load,
you will draw more than this, but this will not be typical.
The X5 is provided with the more conventional AC line cord, which
is rated at 15 amps. The circuit ground is attached to the chassis in
the conventional manner.
Under no circumstances should you defeat the ground connection of
the power cord. For your safety, the chassis of the amplifier should
be earth grounded.
Looking at the rear panel you will see the AC power cord receptacle,
a power switch, fuse holder, five pairs of output connectors, a pair of
5 way connectors for remote turn-on, five RCA input connectors and
five XLR balanced input connectors.
Make sure that the power switch is off (down). Plug the AC cord
into the back of the amplifier, and then into the wall. Then turn the
switch on (up). The lights in your house will blink when the power
supply charges the capacitors.
On the front panel, the “Standby” LED indicator should be glowing
blue, indicating that the power is on. The “Power” LED should
not be on. If the “Power” LED is on, don’t get excited, just use
the front panel stand-by button to go to stand-by mode, with the
“Standby” LED on and the “Power “ LED off.
OK, so the amplifier is sitting there in stand-by mode with just the
