## Description

Features: Adopts two high quality TPA3116D2 digital amplifier chips. Sound quality is very good, high efficiency and amplifying power. 50W*2+100W 2.1 channels(left/right channel and subwoofer channel), high efficiency and low-heat. Powered by DC 12-24V, wide input voltage. User can adjust the volume by themselves easily. Applicable speaker impedance: 4-8 ohm. Just connect the power supply and loudspeaker box, enjoy the pure digital music! Power Supply Setup A single power supply is required to power up the EVM. Because most of the pins are PVCC compliant, the PVCC supply also can be used to power the analog supply (AVCC) and can be used to pull up the logic pins for shutdown (SD) control and fault detection (FAULT). GVDD is an internally generated supply for the output FETs and also is used to power the PLIMIT voltage divider circuit on the EVM. PLIMIT is GVDD compliant, but not PVCC compliant. PLIMIT also can be powered by an external supply connected to the PLIMIT pin. (suggested 24V) 4A (max 8A) Current Requirement: Connect according to Speaker Watt Amp = Speaker Watt / Supply Voltage Connect the external regulated power supply adjusted from 12 V to 26 V to the module PVCC and GND banana jacks, take care to observe marked polarity.

Review: The sound quality is very very crispy digital like high quality AV Receiver. - I used this product with Bluetooth module & high bass Sub-woofer. Bluetooth module was connected by different Power supply to stop humming noise from this amplifier, and on this amplifier I have used 12 V 5Amp Smps. This amplifier works more better than my JBL Sound Bar and the main point is that you can control the Bass, high/mid frequency stereo speakers and total volume individually with the seperate volume controllers.
Review: Good amp tested by an audiophile!! - Review From an auiophile. You get the same on aliexpress at a cheaper rate and reason why i got it here is delivery time, desertcart shipped next day. The amp out of the box is well built and performs well. I used a 24v 6A power supply for giving it the best power output. Make sure you are connecting your speakers in series or parallel based on the ohm rating on ur speakers 4 to 8 is what the amp can handle. The highs and mid is absolutely fantastic. The bass however is good and punchy but you can hear content on the bass till like 4000hz, use a filter seperately to cut off the mid highs. I ran at 90% vol for like 3 hrs straight and no issues.

## Questions & Answers

**Q: I have a ac-dc adaptor 24v dc - 2.0 amp. it's giving power but i hear song for a second only when i power off the adopter. please suggest remedy.**
A: The specified Vmax by Texas Instruments is 26V DC for this chip. You can use 24V DC supply safely but be careful the supply is not giving more than that voltage. If you feel lucky enough to get 50+50+100 = 200W output at any time, you have to supply 8 amp current on 24V DC. 200W/24V = 8.333 amp. So you can see the power supply you have is not sufficient for this amp. Maximum you can get 48W (for total 3 channels)  with this power supply.

**Q: Can you work on 12 inch 100 watts subwoofer**
A: I think it's heavy, plz use Max 6or 5 inch

**Q: Can i use a computer smps?**
A: Yoy can use smps.

**Q: Can I use 60watts and two 20 watts subwoofers**
A: No
