Quality directly for return authorization. Aqua - Acoustic Quality will remedy the problem by
repair or replacement, as we deem necessary, to restore the product to full performance.
Products must be returned using original packaging material only. Packing material may
be purchased from Aqua - Acoustic Quality if necessary. This warranty is considered void
if the defect, malfunction or failure of the product or any component part was caused by
damage (not resulting from a defect or malfunction) or abuse while in the possession of
the customer. The warranty excludes the following components:
-Audio tubes
-NOS (New Old Stock) Components
CAUTION: Changes or modifications to this equipment not expressly approved by the

GENERAL SAFETY INFORMATION
The following general safety precautions must be observed during all phases of operation
of this equipment. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture, and intended
use of the equipment. Aqua - Acoustic Quality assumes no liability for the customer’s
failure to comply with these requirements.
• DO NOT operate the product in an explosive atmosphere or in the presence of
flammable gases or fumes. For continued protection against fire, replace the line fuse(s)
only with fuse(s) of the same voltage and current rating and type. DO NOT use repaired
fuses or short-circuited fuse holders.
• Keep away from live circuits. Operating personnel must not remove equipment covers or
shields. Procedures involving the removal of covers or shields are for use by service-
trained personnel only. Under certain conditions, dangerous voltages may exist even with
the equipment switched off. To avoid dangerous electric shock, DO NOT perform
procedures involving cover or shield removal unless you are qualified to do so.
• DO NOT operate damaged equipment. If the built-in safety protection features have been
impaired through physical damage, excessive moisture, or any other reason, REMOVE
POWER and do not use product until safe operation is verified by service-trained
personnel. If necessary, return the product to Aqua - Acoustic Quality for service and
repair to ensure that the safety features are maintained.
• DO NOT service or adjust alone. Do not attempt any internal service or adjustment
unless a person capable of rendering first aid and resuscitation is present.
• DO NOT substitute parts or modify equipment. To avoid the occurrence of additional
hazards, do not install substitute parts or perform any unauthorized modification to the
product. Return the product to Aqua - Acoustic Quality for service or repair to ensure that
the safety features are maintained.

1. Unpacking
To protect the top loading tray mechanism from damage in transit, it has been blocked by
spongy material.
IMPORTANT : If the CD transport subsequently needs to be transported, these
protections should be reinstalled.
PACKING MATERIAL
Please retain the original box for re-use in case your equipment ever needs to be
transported. The packing material has been especially designed to protect your valuable
equipment from mechanical shock in transit.
2. Operation and Features
Make sure the supplied voltage is the one required by the device. Please ensure the
quality of the connecting cables, paying particular attention the coaxial / AES EBU digital
cable. Often, numerous tests have revealed the importance of this cable for obtaining the
best sound quality.
