MS-6 Advanced Version HiFi Power Amplifier LM3886 Amplifier 100W+100W Integrated IC Assembled

MS-6 Advanced Version HiFi Power Amplifier LM3886 Amplifier 100W+100W Integrated IC Assembled

Description:
MS-6 aims for neutral balance in sound. It adopts a replaceable preamp op amp (Different op amps have different sound styles. The default is high-end gold seal LME49720HA) + 3886 parallel amp integrated amplifier circuit structure. Due to the parallel connection of the power tube of amp, the power and thrust of this amplifier have good performance. Under 4Ω load, output power can reach 100W per channel.

Accurate positioning, stable sound field, loose and natural sound, and good low frequency elasticity make it perform well in all kinds of music. HiFi input and output terminals use HiFi devices.

Features:
- Integrated IC power amp for better sound quality, compared with class A power amp
- Integrated IC power amplifier has good stability
- Single piece of 10A output current can meet the needs of most sound boxes. Two pieces in parallel and its current reaches 20A, overshadowing most discrete tube amps.
- Military-grade resistors and capacitors for better details.
- For ALPS27 type audio dedicated potentiometer.
- Class A parallel regulated power supply used in speakers, is used in our audio circuit to ensure good sound quality.
- HiFi capacitors are used.
- Power supply indicating circuit will have different indicating states during normal operation, circuit delay and abnormal operation, allowing you to understand the working state of the machine more intuitively.
- Switch controls the relay, which effectively avoids the poor contact of the switch.
- Super energy supply: 50A big power square bridge + 4pcs daily 12000uF capacitors in parallel to further reduce the internal resistance of power supply while ensuring energy supply.
- All-round protection circuit: C1237+ original relay, safer and more reliable to use.
- All-aluminum solid knob: feel better, laser lettering.
- Input & output terminals: CMC signal input seat + pure copper paint speaker terminal.

Technical Parameters:
- Power (RMS): 100W+100W (4Ω); 70W+70W (8Ω)
- Sensitivity: 200 mV
- Harmonic distortion: <0.05% (1KHz, 1W, 8Ω load)
- Signal to noise ratio: >95 dB

Note: It is assembled and ready to use.

Precautions:
1. It can only be used in areas where AC voltage is 220V and power frequency is 50Hz.
3. Its power cord must be inserted and unplugged carefully to avoid the risk of electric shock.
4. There should be no cracks in the power cord, do not bend excessively, and it is not advisable to press the cord with heavy objects.
5. When moving the machine, please directly unplug the various plugs connected to the machine, and do not pull the power cord.
6. Do not touch the plug with wet hands, otherwise it may easily cause electric shock.
7. Do not disassemble the top cover or base of the machine.
8. Touching any part of the machine will have the risk of electric shock at any time, and it is also easy to damage the machine.
9. If you do not use the machine for a long time, you should unplug the power cord of the machine from the power socket and store it in a dry place.
10. When an abnormal situation occurs, please turn it off immediately and contact our customer service.

General Failure Phenomena & Solutions:
1.Trouble phenomenon: The whole machine is not powered on.
- Possible reason 1: The power plug is not properly connected. Remedy: Reconnect the power plug.
- Possible cause 2: The fuse is blown. Remedy: According to the labeling requirements, replace the fuse again.

2.Trouble phenomenon: The speaker is silent.
- Possible reason 1: The machine is in a protected state. Solution: Check whether the speaker wire is short-circuited.
- Possible cause 2: The signal wire is short-circuited or disconnected. Solution: check and replace the signal line.
- Possible cause 3: The speaker wire is broken. Solution: check and replace the horn.

3.Trouble phenomenon: loud noise
- Possible reason 1: The signal source itself is noisy. Remedy: Replace the signal source with high signal-to-noise ratio.
- Possible cause 2: The signal cable is poorly shielded. Remedy: Replace the signal wire with good shielding.

4.Trouble phenomenon: the left and right channels are confused
- Possible reason 1: The left and right channels of the signal cable are connected reversely. Remedy: The left and right channels are correctly connected.
- Possible cause 2: The speaker cable is connected to the left and right or the positive and negative sides are reversed. Remedy: Connect correctly according to the left and right channel labels.

5.Trouble phenomenon: the power indicator light keeps flashing on
- Possible cause: The machine is in a protected state. Solution: Check whether the speaker wire is short-circuited.
