UNITY GAIN Setting:
Pressing the Unity Gain button on the remote control will cause the “U” symbol to be displayed.
The second press of this button will make the VK-5SE to go into its Unity Gain mode. This will be
indicated by the character “U” on the volume display.
WARNING: Please use this function carefully. as invoking this setting will apply a full scale
signal from the source selected at this time to your power amplifier. If external surround
sound processor is used, set its volume control to low level before switching the VK-5SE into
its UNITY GAIN position.
Overcurrent Protection:
Both channels in the VK-5SE are protected from certain overload conditions via electronic current-
sensing circuits. If an overcorrect condition is detected in either channel (for example, a short in
one of the regulator tubes), the unit will immediately be disabled, its high voltage supplies
disconnected and the output muted. The protection circuit may be reset by turning the unit Off for
a short period of time. However, if the fault condition remains, the unit will again be disabled and
therefore require professional service.
Fuse Protection:
A blown fuse in the VK-5SE is an indication of a serious problem. If a replacement fuse fails as
well, no further attempts should be undertaken. Please contact the factory for professional service.
The proper fuse ratings are as follows:
For 100-120 VAC Units:
2A 250V Slow Blow
For 200-240 VAC Units:
1.5A 250V Slow Blow
Factory supplied fuses should be only replaced with the same type and rating parts.
Servicing
The Balanced Audio Technology VK-5SE should require no service other than changing tubes to
maintain its high performance. The vacuum tubes used in the VK-5SE are high-quality 6H30s and
5881s rated for approximately 5000 hours of use. Please direct any further service inquiries to the
factory.
Cleaning
To remove dust, occasionally wipe the front and top surfaces of your VK-5SE with a damp soft
cloth. If fingerprints appear, you may use a mild, non-alkaline soap solution. Do not use abrasive
cleaners, as they may damage the fine finish of the unit.
