Cordial Element High Fidelity LM1036 + NE5532 Lead Tone Board No Noise DC Tone Board Send Cap

Cordial Element High Fidelity LM1036 + NE5532 Lead Tone Board No Noise DC Tone Board Send Cap

Description:
- this plate advantages: PCB circuit design is reasonable, the full consideration of single point grounding, no ac interference sound, high signal-to-noise ratio. The measured with TDA7294 for level, no source input ears close to speakers can hardly hear noise, high bass control range wide, bass, full, strong sense of strength strong, good elasticity, to put freely, has good diving; Alt delicate, soft, fully, ductility, no obvious hoarseness. To TDA7294 for good listening level, highly bravery taste, is the rare "digital tone plate.

Finished product specification:
- 132 x51x30mm (length x width x is high, does not contain the potentiometer handle length)
- Potentiometer axial spacing: 35.56 mm
- This amplifier volume, pitch, balance control system, its core is to use national semiconductor company's high quality tone circuit LM1036N, match with the big S fine op-amp NE5532N do level 5 times amplification up broadening effect, it is suitable for most of the later stage amplifier
- LM1036 is to use dc level control volume, pitch (Alt bass), balance of double track digital tone integrated circuit, built-in loudness control circuit.
- The dc level control has the advantage of high bass adjustment each other is not affected, potentiometer use common product and long wire connected to the outside is introduced, noise control is very smooth.
- This board should dispatch send potentiometer plastic knob 4 (color randomly)
- The main properties of LM1036:
- Work voltage 9 - 18v (usually use 12-15 v),
- Signal to noise ratio (SNR) 90 db,
- Tone control range 15 db,
- Volume control range 80 db,
- Distortion is only 0.03%.
- LM1036N its high resolving power and bass strength is admirable, clear sound natural smooth, power amplifier is tones of high-quality goods, believed that the general enthusiasts in many electronic journals also talked about.
- The circuit design LM1036N in front, NE5532 on the back, input impedance is high, low output resistance group, in order to enlarge scope, increase the signal-to-noise ratio. If NE5532 put ahead of amplification, higher electric straight into the LM1036N easy to cause the overload, distortion.
