PREAMPLIFIERS-MIXERS<br />

1052<br />

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 />
