D Class Module for 3 way

DQ828 · 15th November 2010, 08:34 AM

I'm looking for recommendations for a D class module to go with a pair of 3 way speakers I'm building.

Ideally the module would have 3 channels, two at about 50W & one at about 150W.

I'm after something that is know to be good

If you have any thoughts please put them forward.

If is not very urgent, you might check Connexelectronic for such product in few weeks from now.

Christi..

That sounds very interesting.. I am building some three way speakers soon with minidsp boards acting as crossovers and will require something similar. Do you have any more details or hints that will help me to decide how to amplify them?

Kind regards,

Jai Stanley

Hi Christi

Can you give us any advance specs? What is the noise floor like?

Edit: I would like to see an amp that has I2C inputs

I will write the preliminary specs. and publish in my class D section in the following days. I2S inputs not I2C, right ?

No: I2C.

I²C, actually. Some DSP chips use this protocol.

Since im in the same boat as DQ828, i'll take the liberty of asking some questions my self

Christi
What is your best sounding amp?
Your amps are much cheaper than Hypex UcD HG HxR modules. Can these be compared sound quality wise?

Im interested in all digital amp with S/PDIf in and DSP control (via USB) for crossovers and EQ. TI have some very nice examples of this (TAS5631). Will your solution be comparable?

41Hz Amp 9 has four channels, low distortion through a 24V supply, and can be purchased as an assembled board as of recently.

Connect the third and fourth inputs/outputs to make it three channels, ideal for the bass channel. I am using a couple of amp6's and a TA10.1 but hope to move to dual amp9s unless I see something better for similar money.
