7.0 BASIC OPERATION
With all connections made and secured, and with all cables tucked away, you
are now steps away from enjoying the sound quality of your I-30HD.
Also it
is a good idea to remove the tube cage and ensure that the tubes are seated
well before connecting to AC power, just in case they became loose in ship-
ping.
Then turn on your I-30HD in the following manner:
A. Press in the main power switch on the front panel. Immediately you will
see the front panel VU Meter’s backlight illuminate and where you will also
see the tubes start to glow. There is a 20 second delay before all the tubes
are operating normally, this is called a “Soft Start” to increase the longevity of
the tubes.
Allow the unit to warm up for another 1-2 minutes before using. Do not turn
the amplifier on and off until you have warmed up the system for at least 3
minutes.
B. While the unit is heating up, make sure the Volume Control is turned
counter-clockwise, to a lower level. This is good practice as not to damage
your speakers accidently should you have the volume turned up all the
way and one of the selected inputs has an audio signal present.
C. Select the desired Source Input by rotating the Input Selector Switch on
the front panel to the desired input setting.
D. Turn on the Input Device and, for an example a CD, press play on the CD
player.
You are now ready to begin listening to music. Adjust the volume control to
a comfortable and desired sound level.
NOTE: It is good practice for the first 480 hours play your selected music at
normal listening levels to further burn in the tubes and all components.
8.0 Removing the Protective Tube Cage:
To enhance your visual
enjoyment of your I-30HD Integrated Amplifier you may use a long shaft,
magnetized, Philips/Star-head screwdriver to access the mounting screws
accessible though the holes on the top cage (cover).
WARNING!
Take care in not
touching or handing
or cleaning HOT tubes
as they may cause a
serious burn or they
may shatter cutting you.
Keep Children Away.

6.
NEVER
bypass any fuse or replace any fuse with a value or type other
than those specified.
7.
NEVER
expose the I-30HD to extremely high or low temperatures. If the
integrated amplifier has been taken out of storage from an unheated envi-
ronment, let the unit acclimate to room temperature before making any
connections and applying power to the unit.
8.
ALWAYS
keep electrical equipment out of reach of children. This unit
has a Protective Cage / Tube Cover which guards against accidently
touching the glass tubes that are used for either power conditioning, am-
plification, or serving as a VU Meter when the product is in use, thus
avoiding a potential injury and burn. Keep children away. Do not handle
the tubes when hot, or wet them. Only touch the tubes only when they
are cold and the unit is unplugged from its source of AC Power.
9.
ALWAYS
unplug sensitive electronic equipment such as this unit
during lightning storms.
CONGRATULATIONS!
NOW YOU ARE READY TO START!
4.0 Installation & Placement
The I-30HD as is the case with any tube equipped device is more sensitive
than most other types of audio components to EMI (electro-magnetic inter-
ference) from power supplies and motors including vibration. Consequent-
ly, it should be placed at a minimum distance of 18 inches from power sup-
plies, turntables, tape decks, AC line filters, etc..
One should never place another component directly on top of this integrat-
ed amplifier, and as good practice, it is not recommended to directly place
this component on another audio component that generates heat.
NEVER PLACE THIS COMPONENT ON TOP OF A LOUDSPEAKER.
Vibration picked up by the tubes will damage them and shorten their useful
life.
When dressing cables, take care as to tuck away loose cables so someone
may not trip on them.
Allow also for ample air circulation around the I-30HD.
