Operation Manual

  1. Read these instructions.

  2. Keep these instructions.

  3. Heed all warnings.

  4. Follow all instructions.

  5. Do not use this apparatus near water.

  6. Clean only with a dry cloth.

  7.  Do not block any ventilation openings. Install in accordance with the 

manufacturer’s instructions.

  8.  Do not install near any heat sources such as radiators, heat registers, 

stoves, or other apparatus (including amplifiers) that produce heat.

  9.  Do not defeat the safety purpose of the polarized or grounding-type 

plug. A polarized plug has two blades with one wider than the other. 

A grounding-type plug has two blades and a third grounding prong. 

The wide blade or the third prong is provided for your safety. If the 

provided plug does not fit into your outlet, consult an electrician for 

replacement of the obsolete outlet.

 10.  Protect the power cord from being walked on or pinched, particularly 

at plugs, convenience receptacles, and the point where they exit from 

the apparatus.

 11. Only use attachments/accessories specified by the manufacturer.

 12.  Use only with a cart, stand, tripod, bracket, or table specified by the 

manufacturer, or sold with the apparatus. When a cart is used, use 

caution when moving the cart/apparatus combination to avoid injury 

from tip-over.

 13.  Unplug this apparatus during lightning storms or when unused for 

long periods of time.

 14.  Refer all servicing to qualified service personnel. Servicing is required 

when the apparatus has been damaged in any way, such as power-

supply cord or plug is damaged, liquid has been spilled or objects 

have fallen into the apparatus, the apparatus has been exposed to rain 

or moisture, does not operate normally, or has been dropped.

 15. Use the mains plug to disconnect the apparatus from the mains.

 16.  WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO 

NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

 17.  DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING 

AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS 

VASES, ARE PLACED ON THE EQUIPMENT.

 18.  THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN 

READILY OPERABLE.

   TO PREVENT ELECTRIC SHOCK, DO NOT REMOVE TOP OR BOTTOM 

COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO 

QUALIFIED SERVICE PERSONNEL.

   TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE  

AC MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE 

AC RECEPTACLE. THE MAINS PLUG OF THE POWER SUPPLY CORD 

SHALL REMAIN READILY OPERABLE.

WATCH FOR THESE SYMBOLS:

The lightning bolt triangle is used to alert the user to the risk of electric 

shock.

The exclamation point triangle is used to alert the user to important 

operating or maintenance instructions.

IMPORTANT

VRacks require Class 2 output wiring.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as 

preamplifiers or tape decks directly above or below the unit. Because this 

amplifier has a high power density, it has a strong magnetic field which can 

induce hum into unshielded devices that are located nearby. The field is 

strongest just above and below the unit.

If an equipment rack is used, we recommend locating the amplifier(s) in  

the bottom of the rack and the preamplifier or other sensitive equipment at 

the top.

Important Safety Instructions

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject 

to the following two conditions: (1) This device may not cause harmful 

interference, and (2) this device must accept any interference received, 

including interference that may cause undesired operation.

CAUTION: Changes or modifications not expressly approved by the 

party responsible for compliance could void the user’s authority to 

operate the equipment.

NOTE: This equipment has been tested and found to comply with 

the limits for a Class B digital device, pursuant to part 15 of the FCC 

Rules. These limits are designed to provide reasonable protection 

against harmful interference in a residential installation. This equipment 

generates, uses, and can radiate radio frequency energy and, if not 

installed and used in accordance with the instruction manual, may 

cause harmful interference to radio communications. However, there is 

no guarantee that interference will not occur in a particular installation. 

If this equipment does cause harmful interference to radio or television 

reception, which can be determined by turning the equipment off and 

on, the user is encouraged to try to correct the interference by one or 

more of the following measures:

•  Reorient or relocate the receiving antenna.

•  Increase the separation between the equipment and receiver.

•   Connect the equipment into an outlet on a circuit different from that 

to which the receiver is connected.

•  Consult the dealer or an experienced radio/TV technician for help.
