DESCRIPTION
AT 10Z
volume control is made of a control circuit with a 6 position (5 + off)
selector. It can be inserted between the amplifier “4 Ω” output and the inputs of
1 or more loudspeakers having a 4 Ω total impedance.
The 6 selector positions correspond to:
1.
OFF (the loudspeaker is muted / not connected)
2.
24 dB attenuation
3.
18 dB attenuation
4.
12 dB attenuation
5.
6 dB attenuation
6.
Bypass (no attenuation).
Note:
the volume control input impedance is always about 4 Ω,
independently of its selector position.
Its max. power is 10 W.
Position 1 (off)
Z1 = 3.9 Ω
Positions 2÷5
Position 6 (bypass)
