Features of Array 2.1 SE 300B/805 Integrated/ Power Amplifier
Selected and matched 300B, 805 and 6922 tubes
Can be switched between Integrated amplifying mode (Blue light on switches
will glow) and Power amplifying mode (RED light on switches will glow) by
pushing the two toggle switches to
mode (indicated as Bypass and Integrated) on the back panel
A remote control featuring volume control function and muting is supplied
Four line stage stereo inputs (Integrated amplifying mode)
One line stage stereo inputs (Power amplifying mode)
Separate wide-band audio power transformers
Separate wide-band audio output transformers
All transformers are electrically isolated and mechanically shock-mounted
Additional internal damping material for added control of mechanical resonance
the same direction of the desired
4 and 8-ohm output impedance taps for optimum speaker impedance matching
The internal wiring circuit is welded through completely manual lap welding,
with uniform and firm welding points. All insulating wires are silver-plating
flame retarding wires
Vibration-absorbing elastomer feet
Fuse protect amplifier circuit in case of over current

Safety Instructions for JAS Vacuum Tube Amplifiers
1. Never disassemble the unit as you may be exposed to dangerous voltage. In case
of operational malfunction, please contact the nearest authorized service center.
2. Do not attempt to alter the unit in any way. This device has been laboratory
tested and adjusted to optimal operation condition.
3. the two toggle switches on the back panel must be pushed to the same direction
in selecting the desired mode (indicated as Bypass and Integrated) of operation.
4. Vacuum tubes dissipate heat in high temperature.
a. Do not touch the tubes with bare hands during operation. It might cause
sever burns.
b. Do not expose the tubes to moisture. Do not clean the device with wet towel.
Water or other fluid will cause severe damage to the unit, and in some case
may cause the tubes to burst and/or the unit to catch on fire.
c. The vacuum tubes will take at least 5 to 10 minute to cool down.
d. Do not leave the device within reach of children.
5. This device should be kept far from any heat sources and flammable substances.
Dry condition and good ventilation are required.
6. Electron tubes are fragile and easily be broken. Do not subject this device to any
strong impact.
7. When the device is in operation
a. Do not move the device from place to place.
b. Do not attempt to chance the vacuum tubes.
c. Do not disconnect the speakers from the amplifier; doing so may result in
excess current spike which may destroy the vacuum tubes and the entire unit.
8. This device is rated to operate on 115v/230v according to local main supply.
Power should be switched off during thunderstorm or during a long period of
non-operation.
9. Before operating the device, the amplifier should be properly connected.
10. Fuse of proper rating should be used as replacement when necessary. The
maximum allowable current is indicated at the back of the unit.
11. During incidents of smoke, fire, unusual sound or smell emerging from the
device, switch off the unit and unplug the power cord immediately. Contact the
nearest authorized service center.
12. Warranty is void if the unit is operated with non JAS Audio approved vacuum
tubes. Contact your JAS Audio dealers for recommendation of non-factory tubes.
13. JAS Audio and its authorized distributors accept no liability for any financial
losses or human and pet injuries due to operation of the unit that violate the
