QUAD VA-ONE+, Owner'S Manual

Page: 7 / 12

PRECAUTIONS
Install this unit where good ventilation and heat radiation are assured. Do not install where the temperature is abnormally high
such as in direct sunlight, or where it is dusty or humid, as this could result in damage to this unit despite proper heat radiation.
Do not install this unit where it will create a distraction when driving a car.
Installation location
The amplifier has many vacuum tubes, generating considerable heat. Never close the ventilation holes located on the vacuum
tube cover and the bottom plate. If the amplifier is installed on a rack or the like, secure ample space for cooling and leave the
door open. Do not pile up other items on the amplifier and never put books or magazines or CD/DVD cases on top of it. This
can cause malfunctioning.
Note:
For efficient heat dispersal, do not install this equipment in a confined space such as a book case or similar unit.

SETUP
Connect the music source to a suitable input on the unit. Connect your loudspeakers to the Loudspeaker Output terminals. Set the
volume to minimum, connect the unit to the mains supply and switch on. The amplifier takes 30 seconds or longer to warm up
before you can use it.
The VA-ONE+ is also able to drive headphones from the front panel jack. Inserting the headphone plug will automatically switch
off the speakers.
Analogue interconnect cables should be low capacitance and well screened. Avoid excessively long analogue or digital cables.
CAUTION
The volume should be set to minimum when you switch on the unit. When the unit is playing a music track, adjust the volume knob
slowly and keep the volume at a comfortable level. Listening to loud sounds for a long period can damage your hearing
permanently. If you hear distortion, you may be listening too loud. Turn the volume down.
There are no user adjustable settings inside the unit. Please do not remove the top cover as this will expose high voltage parts which
present a danger to life.
The unit generates heat while working, so it should be placed in a well-ventilated position, and enough space is required behind
it to ensure that leads are not unduly strained or damaged.
Very frequent switching on and off of any electronic equipment puts some stress on components, particularly in the power supply.
The unit should be switched off when not in use to save electricity and to maximize operating life of the valves.
Do not plug rechargeable headphones or earphones into the front panel jack as these may cause damage.
Standby Mode
VA-ONE+ will be in standby mode when powered on. The Bluetooth LED indicator on front panel is lightly lit. Press any button on
the front panel or the standby button on the remote control to bring VA-ONE+ out of standby.
Note: VA-ONE+ will be switched to the Bluetooth source input when the unit is activated for the first time, and switched to the last
input source used after that.
Users can press on the remote control to bring VA-ONE+ in or out of Mute mode when playing music. When entering the
Mute mode, the LED indicator will flash.
