Notice:

 

1> This attenuating tone circuit will cause signal loss and reduce the volume. The use effect will be better if it is equipped with an active preamplifier.

 

2> Due to different assembly batches, the types, brands, models, specifications and parameters of some components on the finished board will be slightly different, but we will ensure the quality of the entire board. If you mind these, please do not purchase.

 

Description:

 

High quality continuously adjustable treble alto and bass passive tone control circuit board. The circuit is a classical attenuating tone circuit. The passive attenuating mode works without power supply. Attenuating passive tone has no negative feedback, small distortion and good transient response, but it has certain attenuation to the signal. It is Generally it is used after CD or after preamplifier, before power amplifier. It can also be used between CD and preamplifier.

 

The value of the tone control range is ±10dB, and the insertion loss is -10dB. Using this tone system, the circuit gain will be reduced by more than one time. When the three potentiometers are placed at the midpoint, a flat frequency response can be obtained, which can be easily matched with the rear stage of the vacuum tube amplifier or Transistor amplifier, and can also be used between the CD and the preamplifier.

 

Exquisite FR4 double-sided fiberglass board, high-quality PCB, Size 142x54x2mm ; Imported 2 to 3W metal film resistor, Sweden EVOX or Italy AV or Germany WIMA and other high voltage withstand capacitor assemblies, three original Japanese blue shell 500K double connected potentiometers are used for independent adjustment and control of treble, alto and bass, and three standard terminals are convenient for signal input and output connection. The interval between potentiometers is about 2.15cm.
