Product description
Preamplifier for two channels (stereo) with tone control, balance adjustment and loudness control. The kit is built around the IC TDA1524A, which is an integrated amplifier. The amplifier can boost the input signal with up to 20dB and provides control over bass, treble, left/right balance and loudness. Bass and treble can be boosted or attenuated with ±15dB.
* Supply voltage: 12 - 15VDC
* Current consumption: 50mA
* Amplification: 20dB max
* Maximum output level: > 3V RMS
* Maximum input level: > 300mV G=20dB, > 3V RMS G=0dB
* Input impedance: 10kohm
* Output impedance: 300ohms
* Frequency response: < 10Hz to > 50kHz ±1dB
* Distortion (1kHz): < 0.1% at 1V output level
* Signal/noise ratio: > 85dB G=0
* Bass adjustment: ±15dB at 50Hz
* Treble adjustment: ±15dB at 15kHz
* PCB dimensions: 113 x 66mm
Please note that the capacitors marked C11, 12, 13, 14 and 16 are NOT needed and are not included in the kit. 100nF (0.1uF) ceramic capacitors can be mounted if additional power filtering is wanted. Suitable capacitors are art.no. 41003038.
