Your new V90-HPA 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-HPA 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-HPA away from heat such as radiators. No

naked flame sources, such as lighted candles, should be

placed on the unit.

Power Supply Note:

Power Supply Note: Power Supply Note:

Only use

approved

Musical Fidelity DC power supply. The

use of other adaptors or supplies could seriously damage

the V90-HPA.

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-HPA 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-HPA 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.

Connections

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-

HPA before connecting or disconnecting power, changing

leads or inputs.

Using good quality RCA leads (not supplied), connect the

Two headphone sockets are available to allow a greater

range of headphones to be used without need of adaptors.

Connect headphones into the correct output socket of the

V90-HPA.

Note: If connecting into an

existing

system, the V90-HPA

can conveniently be connected to the TAPE REC outputs of

any pre- or integrated amplifier. If the TAPE REC outputs

are still required by e.g. tape or CD recorder, then the

OUTPUT

OUTPUTOUTPUT sockets (back panel) of the V90-HPA reproduce

the input source currently selected by the setting of the

OUTPUTOUTPUT sockets are unaffected by the

volume control and are therefore suitable for recording

either from LINE or USB inputs.

Plug the DC connector lead from the power supply unit into

the V90-HPA power inlet socket, and plug the adaptor itself

into a convenient wall mains outlet. The blue LED will light

On the host computer, a new device will be available,

whenever the V90-HPA is plugged in. Use this device to

listen to music stored or played from this host computer.

CD, MP3, WAV files played on any software should now

play through the internal USB DAC.

This device works with the normal USB audio drivers as

supplied with Windows XP, Windows VISTA, Windows 7, 8

and Apple OS-X and later. Musical Fidelity does not supply

or support any third party or update drivers for this device.

The computer drivers for the USB input of the V90-HPA

should install automatically. If they do not, please consult

computer system administrator/technical support. To check

correct installation follow these steps:

PC /Windows users

PC /Windows users PC /Windows users

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-HPA 24/96” appears under PREFERRED

AUDIO DEVICE tab.

Mac users

Mac users Mac users

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-HPA 24/96” is selected under the

OUTPUT tab. If the computer’s warning sounds/chimes are

to played through the internal 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 unit on

a USB hub/splitter alongside other USB components.

With the USB cable plugged in, the internal USB DAC is

automatically recognised no matter what input is currently

selected. When INPUTS selector switch is set to USB, the

green LOCK LED will light to show that the USB DAC is

correctly setup. The green LOCK LED goes out when the

INPUTS switch is set to LINE position but the internal USB

DAC is still connected and ready to use whenever required.

Use

Use Use

With volume turned down, switch unit on and plug in

headphones. Select USB or LINE INPUT as required using

the input switch. Adjust the volume control for a comfortable

listening level, sit back and enjoy the music.

These products have been designed so that it may be left

on indefinitely, but please note that the mains adapter may

become warm to the touch - this is normal.
