Operation
Operation of the ZOTL10 amplifier is straightforward. It is not an integrated amplifier, but can
be used with a high-level source such as a preamp, CD player, DAC or electronic crossover. We
do recommend that it is paired with a preamp. The amplifier has one set of speaker binding posts
per channel. There is a volume control on the front panel that can be used or not depending on
which input the source is connected. There should be only one source connected to any of the
three inputs. Speakers from 2 ohms to 16 ohms can be connected to the speaker terminals. You
will not damage the amplifier if there is nothing connected to the speaker terminals, but we
advise that speakers are connected when the amp is in use, to optimize the function of the
protection circuit.
When the amplifier is powered up, the tube high voltage is delayed until the tubes are heated.
This takes about 45 seconds. A brief burst of electronic noise that sounds like static is normal.
The amplifier should quickly smooth out into its normal musical output. Be sure that the
amplifier is operating in a well ventilated environment to ensure the heat from the tubes
adequately dissipates.
Power Sources
The universal input automatically adapts to the input voltage almost anywhere in the world. The
voltage is rated to work with any voltage between 100VAC and 240VAC, and from 50Hz or 60
Hz.
Inputs
There are three different inputs. However,
only one input can be used at one time
. The three
are described below:
Direct Input: a stereo pair of RCA jacks go straight to the amplifier with nothing in the path.
XLR Inputs: a stereo pair of unbalanced, combo XLR and Phone plug jacks are also available.
Each 3 pin XLR contains one stereo channel. The XLR is standard Pin 2 hot.
Volume Control Inputs: There is another pair of RCA jacks that go through the volume control
located on the front panel when using the amplifier with a source device that does not have a
volume control. It is a Japanese ALPS Blue Velvet volume control.
