5 Volume 2
Please Read this Important Note:
Be very careful to check that the rear chassis power selection switch is set
to the correct local line voltage position (either 230 or 115 volts) before using
your machine!
Before connecting any equipment make sure that any machine to be
connected is turned off (on the Volume2 rear panel the power switch must be
pushed down).
Turning the Volume 2 on and off: The Volume 2 should always be the fi rst to
be turned on before either power amp or active loudspeaker. In powering
down the reverse should take place (fi rst turn off amps/speakers followed
by the Volume 2). In connecting any cables be sure that the Volume 2 and all
machines affected are turned off.
It makes good sense to think about where you place the unit before connecting
it. It should be positioned so that you can easily reach it, but there are other
considerations. Try not to place it near heat sources or in direct sunlight, and
avoid exposure to excessive vibrations, dust, heat, cold or moisture. It should
also be kept away from transformers, motors, power amplifi ers and digital
processors.
• Do not open the case. You may risk electric shock and damage to your equip-
ment.
• Leave repairs and maintenance to a qualifi ed service technician. Should
foreign objects fall inside the case, contact your authorized dealer or
support person.
• To avoid electric shock or fi re hazards, do not expose your unit to rain or
moisture.
• If the danger of lightning is foreseeable, unplug the unit. Never touch a
power cable during a thunderstorm—danger of life!
• Always unplug the cable by pulling on the plug only; never pull on the
cable.
• Never force a switch or knob.
• Use a soft, lint-free cloth to clean the case. Avoid cleaning agents as they
may damage the unit. if necessary, use an acid-free cleaning oil instead.
The power supply was carefully engineered to provide clean and consistent
current – an important prerequisite for excellent audio. Built around a toroidal
transformer, the power supply generates a minimal electromagnetic fi eld with
no hum or mechanical noise. The output side is fi ltered by an RC circuit to
extract noise and hums inherent in commercial AC power.
All audio-related components are fed by two separate voltage regulators to
minimize disturbance from other components.
An AC power cord is included for connection to the standard 3-prong IEC
connector. The transformer, power cord and IEC connector are VDE, UL and
CSA approved. The AC fuse is rated at 250 mA (230 V version) or 500 mA (115 V
version).
