SAFETY PRECAUTIONS

WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should be
taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with wet
hands.

• The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the
presence of uninsulated “dangerous voltage” within the product’s enclosure that may constitute a risk of
electric shock to you.

• The exclamation point within an equilateral triangle is intended to alert the user of the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the unit.

• Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.

• Unplug the Preamplifier Tuner from the AC outlet when plugging in or unplugging cables, when left
unused for an extended period of time, when moving, or when you suspect lightning in your area.

• Prevent damage to the power cord. Do not bend, pull, place objects on, alter, etc. Replace the power cord
if it becomes damaged. Always grasp the plug on the power cord when plugging in or unplugging the
Preamplifier Tuner from the AC outlet.

• Your system may produce sound levels capable of causing permanent hearing loss. Do not operate for
extended periods of time at high volume levels.

• Make sure the Preamplifier Tuner is placed on a level surface.

• The Preamplifier Tuner is equipped with raised feet to provide ventilation, reduce acoustic feedback, and

provide protection against scratching the surface the unit is resting on. We advise against removing or
altering feet.

• Do not stack anything on top of the Preamplifier Tuner (processor, source, etc.) Leave a minimum of 2”
clearance from the top of the Preamplifier Tuner to the next shelf (or component) to insure proper
ventilation.

• The Preamplifier Tuner should be located away from other sources that may be sensitive to heat.

• Do not perform any internal modifications to the Preamplifier Tuner.

• Always connect the Preamplifier Tuner’s power cord to an unswitched AC outlet for normal operation.

• If young children are present, adult supervision should be provided until the children are capable of

following all rules for safe operation.

• Do not plug the Preamplifier Tuner’s power cord into an outlet with an unreasonable number of other
devices. Be careful if using extension cords and ensure the total power used by all devices does not
exceed the power rating (watts/amperes) of the extension cord. Excessive loads may cause the insulation
on the cord to heat and possibly melt.

• Mistaking CONTROL OUTPUT or CONTROL INPUT connectors for audio/video inputs or outputs may
damage your Preamplifier or other components.

• Damage may occur to your speakers when the power rating of the driver is exceeded while playing back
music processed by the Preamplifier. Ensure that all the drivers in your system are capable of handling
not only the average power being delivered by the power amplifiers, but also the peak power that is likely
to be generated during strong passages. If you are unsure of your speaker's power rating, contact the
speaker manufacturer or the dealer where you purchased them.

• The Preamplifier Tuner should be serviced by qualified personnel when:

A. The Preamplifier Tuner is not functioning properly.
B. The Preamplifier Tuner was exposed to rain or other type of moisture.
C. The Preamplifier Tuner was dropped, or the chassis is damaged.

THE BASICS

The following is intended to familiarize users with common terms and applications of home audio equipment.

Amplifier - An amplifier takes the output of a preamplifier and increases its level to that necessary to drive a
speaker. Your preamplifier Tuner includes full-range, high-pass, low-pass and mono preamplifier outputs for
connecting to external amplifiers and/or powered speakers.

Preamplifier - A preamplifier typically includes the capability to select from a number of sources, adjust volume

levels and route the signal to an amplifier. Optionally the preamplifier may include the capability to process the
audio signal to adjust for room and listening taste preferences. Your Preamplifier Tuner is capable of adding or
subtracting bass and treble to correct for any needed room equalization. A loudness circuit may be used to further
shape the audio signal for increased clarity and intelligibility at low levels.

Sources - Your Preamplifier Tuner can directly provide audio from its built-in AM/FM tuner. Typically you will want

to connect a number of additional sources (CD, DVD player, etc.) to your Preamplifier Tuner. Your Preamplifier
Tuner is designed to accommodate a wide range of audio sources.

Speakers and Bass Management - An audio system typically uses 2 speakers located front left and right.

Additionally, a sub woofer may be used with good results anywhere in the room. Small speakers usually require a
crossover to remove low frequency (bass) audio and pass this on to a sub woofer. You Preamplifier Tuner
includes an electronic crossover that adds the capability to work with large speakers (full range), or small
speakers (high-pass) and a sub woofer (low-pass). Excellent results can also be achieved using large speakers
and a sub woofer.

Zone - A zone is usually a room with speakers installed in it. Using Code Sets, your Preamplifier Tuner may be

configured for use in systems of up to 16 zones.

MAKING THE CONNECTION

It’s tempting to just plug in your new Preamplifier Tuner and have great sound pour out. Before you do that, take a
few minutes to plan out how you want the Preamplifier Tuner to fit into your audio system. Ask yourself the
following questions:

y What source components do I want to connect to my Preamplifier Tuner? (CD, DVD, etc.)

y What equipment will be receiving the audio? (Amplifier, Powered Speakers, etc.)

The answers to your questions determine how many cables you need to connect to the back of the Preamplifier
Tuner. Good preplanning equals great sound. Keep these recommendations in mind:

y List all components in your system and indicate which jacks of the Preamplifier Tuner each component will be

connected to. Your Preamplifier Tuner has six sets of inputs. It is convenient to connect a DVD player to the
input labeled DVD or a VCR to the input labeled V1 or TAPE, etc. However, your equipment may differ from
the labeling on the back of your Preamplifier Tuner. In most cases you can connect any type of source to any
input (see FREQUENTLY ASKED QUESTIONS). For example, if you have a satellite receiver you can
connect it to V2. You can also reprogram the source name that will appear on your Preamplifier Tuner’s front
panel. (See SETUP - SOURCE NAMES)

y Also note the length of the cable for each component’s connection and describe how it should be routed or

draw your routing scheme below your list. You may want to label each cable with a name or number at both
ends. Use high quality connections to maintain high quality audio.

y Think about the type and length of cable you need and obstacles in the cable’s path (doorways, furniture,

walkways, etc.). To decide which ones are right for you talk to your dealer about the various cable products
that are available.

y For safety, keep all cables out of high traffic areas (hallways or doorways) and away from equipment that

radiates power, including amplifiers, power cords, heaters, etc.

y If you might expand your audio system later, keep these ideas in mind as you plan current cable runs.

y To provide the best tuner reception, make sure the antenna is at least several feet away from the Preamplifier

Tuner and any other equipment that may produce high frequency interference such as Personal computers,
CD players, halogen lamps, etc.

Take a look at the back panel of the Preamplifier Tuner. You will notice that the RCA-type audio input and output
connectors are identified by colors, red for right channel and white for the left channel audio.
