START UP CONTINUED
Now that you have the tubes installed and know what each one is for, hook your
speakers and source up to the amplifier and turn it on.
Be sure to have the vol-
ume control all the way down.
After the tubes slowly light up and begin to work
(about 20 seconds) you can slowly start to raise the volume.
If you hear distor-
tion it means the amp is still warming up.
60 seconds is the official warm up
period before music will play without distortion.
POWER OUTPUT
Your amplifier will drive almost a dead short meaning a 2 ohm speaker wouldn't
bother it a bit.
Because of this unique ability for a single ended amplifier it
is able to drive every speaker with a good frequency balance.
The issue is never
going to be the amplifiers ability to drive a given speaker but rather how loud
it will get and if that volume is satisfactory.
Complex, low efficiency speakers
typically have busy crossover networks which convert some of the initial 1st watt
of power into heat before it ever reaches the drivers.
With only a couple watts,
you don't want to waste any power into heat if you don't have to.
Ideal speakers
are generally simpler designs with higher efficiencies.
INPUT SENSITIVITY
This is the amount of signal required to get full output from the amplifier or
put another way, how much signal it takes to get the amp to clip.
For whatever
reason the industry over the years has typically used 1 volt as the requirement
to bring an amplifier to full power and this is fine.
However, the standard out-
put of almost all CD players is 2 volts.
We designed the Zen amps to use the
full 2 volts to come to full power meaning that with a CD player hooked directly
to the amplifier you would be able to turn the amplifier volume all the way up
and reach the power limit just at the onset of clipping.
This makes it very dif-
ficult to clip or distort the amplifier and consequently the amplifier has the
worlds most graceful clipping—so much so that many people don't even know when or
if the amp is distorting.
