3-INPUTs MONO MIXER<br />
This circuit is a 3-input MONO mixer with<br />
independent level control for every input. It also<br />
incorporates separate BASS and TREBLE controls. It<br />
can be used with SMART KITs 1023 and 1024 to make<br />
its inputs sensitive enough for MICROPHONE and P.U.<br />
Input sensitivity: 150mV. Max. current: 100mA.<br />
V 18 VDC<br />

4-INPUTs INSTRUMENT MIXER<br />
A kit for the musician. It is very useful as it will let you<br />
use 4 instruments at the same time on the same<br />
amplifier input. It has very good mixing quality despite<br />
the simplicity of the circuit and its very low power<br />
consumption makes it possible to use the mixer with a<br />
small 9V battery for a long time. Max. current: 20 mA.<br />

CASSETTE HEAD PREAMPLIFIER<br />
A preamplifier using an IC capable of raising the low<br />
output of the cassette head to a level that will drive<br />
the TAPE IN input of a stereo preamplifier. It works<br />
well with any STEREO preamplifier.Very low distortion,<br />
high amplification factor and very good frequency<br />
response. Frequency response: 20Hz-40KHz. Max<br />
current: 20mA.<br />
V 7-20 VDC<br />

Hi-Fi PREAMPLIFIER<br />
A preamplifier designed for the most demanding Hi-Fi<br />
listeners. It uses the very latest technology in audio<br />
circuits as it is fully DC controlled. It is completely<br />
immune to noise from potentiometers or from pick up<br />
noise from long control wires as they are only carrying<br />
control voltages and not audio signals. Max. current:<br />
30mA. Output level: 1V. Frequency response: 20Hz-<br />
20KHz.<br />
V 12 VDC<br />
