I've got three of Authxl's 'Genius 300' amps, all work fine. Two of them are used running 24/7.
If there's a problem, it is only fair to take it up to Authxl first, and never to make a negative claim without providing details.

Hey Authlxl,

Have you tried the 5616 and 5631 chips and the complimentary TAS3308 / TAS5508 / TAS5518 SoC's?

I read that you are using the Analog Devices ADAU1701 but it would be very cool to investigate what performance gain you could achieve by keeping everything in the digital domain instead of converting to analog to drive the amplifier stage.

I ordered the 5631 EVM board which comes with a TAS5508 onboard but it's currently backordered.


regards,

Hi, Authlxl,
I can't find any info on what is the resistor type of the Blue Alps, but judging from the sound, I think it is plastic, carbon type sounds more warm and fuller.
Also, can u tell me what are the values for the ceramic caps for
c10, c12, c55, c65 and C64,52,40,c7?
And which cap decouples pin64 VDD?
Thanks.

c10, c12, c55, c65 100N/100V tdk ceramic cap x7r
C64,52,40,c7 100N/100V tdk ceramic cap x7r
C5 100N/100V tdk ceramic cap x7r

we have developed one powered mixer use TAS5504+TAS5261+SMPS,if you like we can change TAS5261 as tas5631.

Best sound ,powerfu super bass,clear and excellent treble.

What is the spec. for the tas5615 amp and SMPS .

We have been to the site: Wholesale tas5615 Product-TAS5615 AND SMPS AII IN ONE BOARD

And is interested in buying them. But my Chinese isn't that well.

We would like to know what the standby power consumption is for the amp with no signal on the input?

Dear forumers,
I am a new with minimum DIY skills, but have a Behringer DCX2496 to split my stereo to LMH for tri amp. I plan to removed the passive crossover componets later, when I am more sure that the amp will not send any DC to my speakers.

I am considering a 4 units of 5630 to triamp my speakers. 2 unit in PBTL for bass, and 2 unit on stereo for mid & high.

I got this from TI website
1. Set switches S1 and S2 to PBTL
2. short LEFT+ with RIGHT+ and LEFT- with RIGHT- to speaker.

Please help me with these questions -
1. The built in IC has DCP/OVP/OTP protection. This is sufficient to protect the speakers or need to addon other delays & relays?
2. For PBTL bass, I need to use a Y-RCA cable to feed the RCA L+R inputs?
3. Are there swithces clearly marked on the board to set?
4. Short the speaker wires as above?

Thanks in advance for the replies. Best regards.

Default Hi authlxl! TAS5631 chip please?

Here is a copy of the email I sent to your firm:

a1tall7: Please can you make a Class D AMP using the TAS5631 also? This chip uses digital in for pure digital path: suggest aes/ebu compatible 24 bit /192khz max digital input (but with support for other data input rates such as 16 bit/ 44Khz). This TI chip using pure digital path would be special in the market and many people today wish to maintain digital path until the final speaker output! Also with this amp provide band-pass digital filtering of input signal (using built in equalization capacity of chip?) so that it can be used to active amp speaker drivers and also function as digital crossover/room correction curve (cross-over and equalization frequencies configurable anywhere in the 10-40Khz frequency range. Delay adjustments to maintain the very important phase alignment capacity of all channels.

Then hook up six amps in one box with 1 volume control and remote control (with individual offsets possible for each channel for adjustment purposes) and huge power supply: 4 TAS5631 chips for 8 channels of normal (non-subwoofer loads) and the other two TAS5631 chips for brideged output to 2 subwoofers! Provide 5 discreate digital aes/ebu inputs (10 channel parallel input) to feed the 6 amps for maximum flexibility. NO analogue inputs with their unneeded/unwanted complexity and cost!

Maybe later offer a HDMI decode box that inputs HDMI home theatre standards and that ouputs to 10 channels using aes/ebu digital sdandard!
(again pure digital path)!

Do what Tact Auidio (Tact digital amplifiers and preamplifiers)
did but at 10% of their huge prices and you will dominate the quality pro-audio / home-theater discrete amp market, and greatly expand this market!!

Steven R

Please advise!

Very good recommendations Steven. I to would like a TAS5631 option for all digital system from ADAU1701 dsp to amp, but for now I'm happy with TAS5630.

Be aware for an HDMI device to be HDCP compliant it can only have two channel output via digital. Hopefully with HDCP master key out in the wild someone is willing to make compatible product (multi channel digital out) without official HDCP licencing.

Yes , to get around that they can do what Tact did and use a proprietary digital connector (and drop the aes/ebu out ports) if they built a decoder box to plug into a digital only multi-amp box. I meant to specify 15hz-20 Khz, 40 Khz is outside spec for TS5631. I don't know what extension the chip can do beyond 20 Khz.
