Package Include
1. CO3 Three Band Phase-Linear Crossover Filter DIY Kit (Stereo) -AD797 version
2. Assembly Manual

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. Use of very low distortion high quality audio OPAMP AD797, 0.03% at f=1k Hz typical

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

4. Implement with non-inductance 1% Dale resistors, WIMA film capacitors, and Nichicon FW capacitors.

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

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

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

8. Required power supply: +/-15V 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 Toroidal Transformer
