Removal or Installation of the volume modules - The volume modules can be plugged in, or unplugged from the Platinum mother board. They are
held in place with two plastic snaps which can be released by pinching together. The boards are automatically detected, so when unplugged the DAC will
output the same level signal as it would with them plugged in at 0 dB. The volume knob will now select the input and the remote volume buttons will have
no effect.
Install the Signature DAC Upgrade - This upgrade provides hand matched DAC modules for superior sound quality. These DACs can run at twice
the speed (384 kHz sampling rate) with 1/2 the settling time. The noise level is cut to 1/3 the normal value and the signal-to-noise ratio is up to 145 db.
They are user installable and come as a matched set of four, replacing the existing DACs. Remove the clamp holding the DAC modules in. Pull each module
straight out without tipping or twisting. Align the new module with the pins and push firmly back in. Take care that each connector is aligned. Do one
DAC module at a time.

Each Platinum is comprehensively tested
and the actual outputs measured. A test
plot should be included in your Platinum
like the one below. Just a few comments
on the test plot. Most measurement
systems cannot measure as low a level
as -145 db. That is the noise floor of our
test system which means the Platinum
may measure better, but we cannot see
it. The rise at low frequencies is always
present on our test setup and the right
channel always shows a little more noise
than the left (the right cable runs closer
to the digital input cable).

No “Source” indicated on LEDs - Check for bad cable, or cable plugged into the wrong output on the transport.
No sound - Check that source is valid audio source. Change to a standard CD just to be sure. Check that analog outputs are connected properly. Check
that volume is turned up. Check Single-End or Balanced switch on the back.
Still no sound - connect an analog output from the source directly to the preamp input. Verify that the rest of the system is working. Now move the
same analog cable to the DAC and plug in the analog source to the analog inputs. Verify the DAC pass-through is working. Now plug in a digital source.
You should hear a click and the front display should indicate frequency.
You hear audio clipping (with outboard preamp) - the output level may be too high for your preamp. Check the input specifications on your preamp.
(See Platinum specs). If you do not have the volume option, get it and turn the MSB volume down to -6 dB. This provides the standard 2 V RMS industry
specification.
The unit does not work powered on 240 V - unplug power quickly or capacitors may smoke. The unit is configured for 120 V Check voltage selector
on back.
Frequency readout is off - The Platinum shows the actual input frequency and does not show the upsampling that may occur internally.
96K source indicates 48 k on front panel - Check setup menu of DVD player. Digital output should be set for 96 k output. Some models do not
support this feature and downmix to 48 k
DVD-A source does not indicates 192k - DVD-A players must be upgraded to provide a true 192K output. Production players downmix to 48K.
Many DVD-A disks are produced in 44.1, 48 and 96 k as well.
