PLAYING DTS ENCODED MATERIAL

When presented with a valid digital input signal, it takes the Millennium 2.4.6 a moment to deter-
mine whether the input is DTS encoded or not, and we want to insure that you don’t get a blast
of noise from the analog inputs if it is indeed a DTS disc, so you might hear a click when playing
even a non-DTS disc.

even a non-DTS disc.
The Millennium 2.4.6 automatically
assumes the source is DTS, energizing its output relays
whenever it senses a valid signal at the digital input port. If the Millennium 2.4.6 then deter-
mines the signal is not DTS, it releases the relays after a few moments. The result is that you
may hear the relays clicking whenever a valid digital source is detected.

When the Millennium 2.4.6 is set up for “pass through” operation, the analog outputs from your
Receiver or Preamp are connected to the inputs of the Millennium 2.4.6. In this configuration,
when you play back a disc, the analog noise is presented to the Millennium 2.4.6’s analog
inputs, while the digital DTS data is simultaneously presented to the Millennium 2.4.6’s digital
input because DTS data is placed on a disc where the music data would normally go. Of course,
your disc player can’t tell the difference between the DTS datastream or analog program
sources. It takes a moment for the Millennium 2.4.6 to recognize the digital signal, and then
switch its outputs to substitute DTS for the pass-through audio. A

very tiny bit of the DTS
datastream sound is passed through in that instant, which you then hear as a ‘click’. The audible
DTS datastream sound from the analog inputs is the raw DTS digital data being converted to
audio.

The simplest way to reduce the volume of the DTS datastream sound presented to the input of
the Millennium 2.4.6. is to turn down the volume of the Receiver or Preamp, which is driving the
Millennium 2.4.6. You can then compensate for this reduction by turning up the MASTER level
on the front of the Millennium 2.4.6 clockwise until the volume is satisfactory. However,
the Millennium 2.4.6. is to turn down the volume of the Receiver or Preamp, which is driving the
Millennium 2.4.6. You can then compensate for this reduction by turning up the MASTER level
on the front of the Millennium 2.4.6 clockwise until the volume is satisfactory. However,
DO NOT
switch to Manual Mode with the MASTER level turned up to avoid damage to your system.
If you hear a hissing sound in the background whenever you play a DTS disc it is likely you’re
hearing channel to channel ‘cross-talk’, which means that one channel of your system is
hearing channel to channel ‘cross-talk’, which means that one channel of your system is
cross-
ing over and
talking on another adjacent channel. The very high input impedance and high
gains of most line-level systems make them susceptible to noise on adjacent lines. Try running
the Millennium 2.4.6 in manual mode, and then disconnect the analog outputs from your player
or transport. If the noise disappears, you know this is the source. You can reduce this effect by
moving the analog lines from your player or transport to another input, perhaps physically farther
from the input currently selected. Some rearrangement of the system wiring may be necessary.
Another possible cause is multiple ground paths, or a ‘ground-loop’. Ground-loops can be creat-
ed in
the Millennium 2.4.6 in manual mode, and then disconnect the analog outputs from your player
or transport. If the noise disappears, you know this is the source. You can reduce this effect by

from the input currently selected. Some rearrangement of the system wiring may be necessary.
Another possible cause is multiple ground paths, or a ‘ground-loop’. Ground-loops can be creat-
ed in
any system, and are not specifically DTS related. They are usually characterized by low
frequency humming sounds or pops and clicks when lights or other electrical equipment are
switched on and off, which could manifest itself as a low level hissing sound when a DTS disc is
played. Eliminating any unnecessary interconnects, reducing the length and increasing the qual-
ity of those you do need, and adding ground straps between components are all steps to cir-
cumvent this problem.

NOTE 1: When the Millennium 2.4.6 is inserted into a pre-existing system, rather than employed
as a stand alone DTS Decoder/Preamp the audible DTS datastream may be more apparent. In
order to mask this artifact during normal operation, simply set the Millennium Master gain at a
higher level (ie. 3 o’clock) and the preamp/receiver ahead of the Millennium at a lower level (ie.
9 o’clock). Final adjustment of both paramenters suggested is a matter of a few moments of
experimentation once you have your Millennium 2.4.6 installed.

NOTE 2: Due to occasional software data errors, the Millennium 2.4.6 may stop decoding the
DTS bit-stream. If this occurs, turn the power off and re-start, with the MASTER gain off.
