Audio Kits
Balanced Input Mic Pre-Amp Kit
Champ 0.5 Watt Amp Kit
(SC April ’95) Designed by Altronics.
This kit will amplify a microphone (low
level signal) to a line level to connect
into an amplifier. It features high
performance with a balanced mic input
as well as two auxiliary inputs which
are all mixed. It can be configured to
operate from either a single ended
power supply (12V to 30V DC), or a
split rail power supply (±15V to ±30V
DC), making it ideal to build into any
existing amplifier.
(SC Feb ’94) Physically about the same size
as a standard 9V battery, this compact little
amplifier delivers 0.5W of power into 8 ohms
from a 9V battery. Ideal for beginners, experimenting and small audio projects. Designed
around the LM386 audio amplifier IC, it uses
only a handful of components and works
from 4 to 12V DC.

(SC July ‘08) With this simple circuit
it is possible to make any stereo amplifier deliver double its single channel
power rating into a single load. It uses
just one economy integrated circuit
and a few other components. Full connection details supplied with the kit.
Connects direct to amplifier
power rail.

(SC July ’94) Designed to complement the
K 2115 champ amplifier. When it comes to simplistic but effective circuit design, you can't beat
the pre-champ. It has been designed to complement the CHAMP kit, which when combined,
boosts the overall gain. Ideal for electret microphone pre-amplification. Requires 6 to 12 Volts
DC. PCB size 46 x 36 mm.

(EA May ‘92) Simply connects between the audio source and the amp
allowing customised audio output. It
features dual output, one for bass and
the other for mid/treble. Because no
passive crossover is required there are
no losses involved. One kit per channel
required. Adjustable between 1.8kHz
and 3.6kHz. Requires ±15V DC power
supply or may be powered off amplifier
power rail.
