Category: Audio Circuits / Tone Balance Views: 733 Rank: 2 The LTC®1560-1 is a fully integrated continuous-time filter in an SO-8 package. It provides a 5-pole elliptic response with a pin selectable cutoff frequency (fC) of 1MHz or 500kHz. Several features distinguish the LTC1560-1 from other commercially available high frequency, continuoustime monolithic filters visit page.
Related circuits Play any stereo disc or tape and then set the amplifier to mono The meter will show volume and tone control balance between left and right stereo amplifiers. For maximum convenience the meter is a zero-center type. Resistors are five percent or better and the diodes a matched pair. Optimum stereo level and phase balance occurs for matched speakers when the... This high-Q notch filter is based on the "Twin-T" design. It produces a very deep notch in the response curve at about 59.7 Hz. This is useful to remove 60-Hz hum and noise from audio recordings or live performances. Response is down over -60db at the center point. Digital Volume Control with DS1669 This digital volume control has no pot to wear out and introduces almost no noise in the circuit. Instead, the volume is controlled by pressing UP and DOWN buttons. This simple circuit would be a great touch to any home audio project. Sometimes, for a variety of reasons, it would be nice to vary the width of the `sound stage` when listening to stereo recordings. Although technically this is anything but hi-fi, it is a useful addition to PC speakers, or even for the music centre in the listening room. This circuit could be used for replacing your manual volume control in a stereo amplifier. In this circuit, push-to-on switch S1 controls the forward (volume increase) operation of both channels while a similar switch S2 controls reverse (volume decrease) operation of both channels. A readily... When L R signals are equal, no output is present from Ul, and pin 6 is at a steady 4.5 V. Unbalanced audio causes the LEDs to vary in brightness, This preamplifier was designed as a stand-alone portable unit, useful to control the signals generated by guitar pick-ups, particularly the contact "bug" types applied to acoustic instruments. Obviously it can be used with any type of instrument and pick-up. It features a -10dB, 0dB and +10dB... Passive low pass RL filters
