For customized frequencies f1 and f2, please specify the frequencies in purchase order.

Features

1. Support three-band (bass, mid-range and treble frequency) linear-phase crossover filter for stereo channel. Frequency crossover frequency can be set by different resistor sets shown in the Table I.

2. Attenuation: 80dB/decade or 24dB/octave, linear phase.

3. Maximum input voltage: +/-18V

4. Maximum output voltage: +/-16V

5. Either use of very low distortion high quality audio OPAMP AD797, 0.03% at f=1k Hz typical or low noise OPAMP NE5534

6. Four ALPS 50K POTs are used for the volume control: gain, bass, mid-range, and treble, for 0dB to -100dB attenuation.

7. High power rejection ratio: 80dB and channels isolation: 100dB

8. Symmetric PCB design for both R and L channels.

9. High quality PCB, blue solder mask, double layer, 2.4mm thickness, 2oz copper. PCB dimension: 195(L) x 100(W) mm.

10. Required power supply: +/-15V to +/-18V DC, 120mA

Applications

1. For professional bi-amp or tri-amp applications, it requires exactly the same response time for the bass, mid-range, and treble frequency components.

2. Audiophile low-pass, band-pass, and high pass filters.

Optional:

1. LV30B Positive & Negative Voltage Regulator Kit
2. T20L/T20 Toroidal Transformer or R58 R-core Transformer
