Thank you for purchasing the V90-DAC
digital to analog converter. We sincerely
hope that it will bring you many years of
outstanding listening pleasure.
Your new V90-DAC is designed and built to
provide trouble-free performance, but as with
all electronic devices, it is necessary to
observe a few precautions:
Do not use the V90-DAC near water. The
unit must not be exposed to dripping or
splashing and no objects filled with liquids,
such as vases, must be placed on the unit.
Keep the V90-DAC away from heat such as
radiators. No naked flame sources, such as
lighted candles, should be placed on the
unit.
Only use approved
Musical Fidelity
DC
power supply. The use of other adaptors or
supplies could seriously damage the V90-
DAC.
This Hi-fi product has been tested to ensure
that its operation is not adversely affected by
normal background levels of Radio
Frequency Interference (R.F.I.), and that it
does not itself generate excessive amounts
of interference. However, if a problem
persists, please contact your Musical Fidelity
agent.
Never open the case of the V90-DAC
yourself, as this will invalidate the guarantee.
Place all connecting cables where they are
not likely to be walked on or trapped by
items placed on them.
The V90-DAC will operate in accordance
with its specifications within the following
environmental range:
Temperature 5 to 45 degrees Celsius
Humidity 10 to 90% non condensing
There are no user adjustments inside.
Please refer all service work to an
authorised Musical Fidelity agent.
All connections must be made before the mains adaptor is plugged in,
and before any amplifier connected is switched on. Always switch off
the equipment attached to the V90-DAC before
connecting/disconnecting power, changing leads or inputs.
Using good quality digital RCA (SPDIF) leads (not supplied), connect
the digital coaxial output from a digital audio source (e.g. CD player) to
the V90-DAC socket.
Using good quality optical (TOSLINK) leads (not supplied), connect the
digital optical output from a digital audio source (e.g. CD player) to the
V90-DAC socket (or if input is not already
used).
Note the COAXIAL and OPTICAL 1 inputs are a
shared
input. The unit
will only respond to the first of these inputs to present a valid digital
stream if both are used.
A quality USB A-B cable is required to connect the unit to a computer.
Plug the B (square) end into the socket in the back of the V90-DAC and
the A (rectangle) end into a free USB socket on your computer. Set the
input select switch to “USB”.
Once the unit is plugged in and powered, the computer should detect
the new hardware and install a generic driver automatically (No setup or
driver disk required). The V90-DAC is then ready to play V90-DAC, CD
or any other form of music file recognised by the
computer.
Make sure following the amplifier is turned off. Connect the V90-DAC
left and right outputs to the line level inputs of the amplifier system.
Plug the DC connector lead from the power supply unit into the V90-
DAC’s power inlet socket, and plug the adaptor itself into a convenient
wall mains outlet. The blue LED will light to confirm the unit is ready for
use, and the green LED should also be lit indicating presence of digital
signal.
Turn the volume on amplifier to normal listening levels, set the
input selector switch to desired input, sit back and enjoy the music!
On the host computer, a new mixer will be available, which is the default
mixer whenever the DAC is plugged in. Use this mixer to select the
source or adjust levels if required. CD, MP3, WAV files played on any
software should now play through the DAC. This device has been
designed to work with Windows 98, ME, 2000, XP, Vista, 7 and 8, Linux
and Apple OS
The computer drivers for the USB input of the V90-DAC should install
automatically. To check correct installation follow these steps:
Check the computer has picked up the device and is currently using it
by clicking: (most Windows versions)
- Start
- Settings
- Control panel
- Sounds and Multimedia
- Audio
Check “V90-DAC 24/96” appears under PREFERRED AUDIO DEVICE
tab.
Check the computer has picked up the device and is currently using it
by clicking: (MAC OS X)
- System preferences
- Hardware
- Sound
Check that “V90-DAC 24/96” is selected under the OUTPUT tab.
If the computer’s warning sounds/chimes are to played through the
DAC, make sure it is selected under the SOUND EFFECTS tab too.
This device is a high speed serial data processor, and by its nature,
requires a very high volume of USB bandwidth. It will benefit greatly
from being the only device connected on its USB ‘port’. Sharing the
same port with other devices may cause unwanted artefacts such as
dropouts or temporary loss of signal. This especially includes the use of
the DAC on a USB hub/splitter alongside other USB components.
