1. Introduction

Welcome to B!

Thank you for choosing the Alpha.

The Alpha
amplier system. Especially developed for the enhan­cement of acoustic instruments, it is as well suitable
for other (also electrical) instruments.

With one channel but two independant input stages
(line and microphone/line) the Alpha offers you vari­ous options in signal processing.

40 Watts plus the 8“-twin-cone speaker-system of the
Alpha provide you with a well-balanced tone at all
sound pressure levels.

All AER-systems are subtly dynamically controlled,
which ensures absolute reliability in full load opera­tion despite strikingly small sizes and little weight.

Read on and have fun using your Alpha!

Use only a dry cloth for cleaning. Avoid the use of de­tergents and do not let any liquids seep into the unit.

10. Use only the right fuses with the same current
rating and trigger characteristic as replacements.
Never mend fuses! Pull the mains plug before repla­cing a fuse. Should a fuse blow again after a short
while, the device needs to be checked.

11. Never install your amp close to devices with
strong electromagnetic elds such as large mains
transformers, revolving machines, neon illumination
etc. Do not lay signal cables parallel to power current
cables.

12. There are no user-serviceable components in­side the unit. To avoid the risk of an electric shock,

where they exit from the apparatus.

17. This product may cause permanent hearing loss.
Do not operate for long periods of time at a high
volume level or at any level that is uncomfortable.
If you experience any hearing loss or ringing in the
ears, you should consult an audiologist.

18. The product should be located away from heat
sources such as radiators, heat registers or other pro­ducts that produce heat.

19. Do not place any open sources of re, like can­dles, on the device.

20. Care should be taken so that objects do not fall
onto the device and liquids are not spilled into the
