OPERATIONAL NOTES
SWITCHING ON
The power switch is located on the right hand corner of the front panel. Flip the
switch up to turn on the unit and down to turn off the unit. When powering up or
down this unit, it is recommended to have the MANLEY JUNIOR STEREO DAC muted
as to avoid amplifying powering up/down noises which occur as the digital receiver
"loses clock" with the digital source. Also, it is recommended to mute the MANLEY
JUNIOR STEREO DAC while changing digital input connections or powering up or
down digital sources. Failure to abide by the above recommendations can result in
damage to your loudspeakers if these noises are amplified to excessive levels.
CHANGING THE GAIN
Your MANLEY JUNIOR STEREO DAC has been factory calibrated using precise test
equipment for 10dBs of equal gain in both channels. If you wish to change this
setting, we recommend using a reference test compact disc and either an
oscilloscope if available and/or an AC / VTTM / or DMM meter to measure levels at
the output of the DAC. Remember, never play sine wave test tones at high levels
through your loudspeakers.
SPECIFICATIONS
WARRANTY
All Manley Laboratories equipment is covered by a limited warranty against defects in materials
and workmanship for a period of 90 days from date of purchase to the original purchaser only. A
further optional limited 5 year warranty is available to the original purchaser upon proper
registration of ownership within 30 days of date of first purchase.
Proper registration is made by filling out and returning to the factory the warranty card attached to
this general warranty statement, along with a copy of the original sales receipt as proof of the
original date of purchase. Only 1 card is issued with each unit, and the serial number is already
recorded on it.
If the warranty registration card has already been removed then this is not a new unit, and is
therefore not warranted by the factory. If you believe this to be a new unit then please contact the
factory with the details of purchase.
This warranty is provided by the dealer where the unit was purchased, and by Manley Laboratories,
Inc. Under the terms of the warranty defective parts will be repaired or replaced without charge,
excepting the cost of tubes. No warranty is offered on tubes, unless:
1. a Manley Laboratories preamplifier is used with a Manley Laboratories amplifier, and
2. the warranty registration card is filled out.
In such a case a 6 month warranty on tubes is available with the correct recording of the serial
number of the preamplifier on your warranty registration card.
If a Manley Laboratories product fails to meet the above warranty, then the purchaser's sole
remedy shall be to return the product to Manley Laboratories, where the defect will be repaired
without charge for parts and labour. The product will then be returned via prepaid, insured freight,
method and carrier to be determined solely by Manley Laboratories. All returns to the factory must
be in the original packing, (new packing will be supplied for no charge if needed), accompanied by
a written description of the defect, and must be shipped to Manley Laboratories via insured freight
at the customer's own expense. Charges for unauthorized service and transportation costs are not
reimbursable under this warranty, and all warrantees, express or implied, become null and void
where the product has been damaged by misuse, accident, neglect, modification, tampering or
unauthorized alteration by anyone other than Manley Laboratories.
The warrantor assumes no liability for property damage or any other incidental or consequental
damage whatsoever which may result from failure of this product. Any and all warrantees of
merchantability and fitness implied by law are limited to the duration of the expressed warranty.
All warrantees apply only to Manley Laboratories products purchased and used in the USA.
Some states do not allow limitations on how long an implied warranty lasts, so the above
limitations may not apply to you. Some states do not allow the exclusion or limitation of incidental
or consequential damges, so the above exclusion may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which vary from
state to state.
