Hi Pa,

Not yet started with the UcD700, to busy with some interesting OEM customers

Will be something for the end of this year.

For the moment you have to live with the UcD400, you can use two of in bridge?

Regards,

Jan-Peter

Maybe you should test first to see if 400 W is enough? The difference between 400 and 700 watts is only 2.43 dB in sound level.

Hi !
thanks for your answers...
i'hope Oem will sign, they would be silly not doing it :-)

yes, 200 watts into 8 ohms (ucd400) is far enough in terms of sound level or concerning the output voltage, but a 15" need a lot of current to work well, i'have several 100 watts amps and when connected to the 15" the only thing you can have is noise, i think they can't drive the speaker due to the inductance effect of the speaker.

Hi...

What will be a suitable voltage (AC) for the UcD700 and UcD1000?

I'm hunting parts for a future PSU for these amps, and I found a batch of 1400VA transformers that might come in handy...

Stefan,

The maximum voltage of the UcD700 (1000) will be something about 85VDC. The max. AC voltage +/-60VAC.

Regards,

Jan-Peter

Hi Jan-Peter,

When is the UcD700 expected to surface

If used with a 45V AC toroid, how much power can I expect (at 8 ohm)?

Hi Duck-Twacy,

The UcD700 (or more) will be released before summer.

Power in 8 ohm: 45V-10%=41,5V --> (41,5^2)/8=215W

Small correction

45-10%=40,5 --> (40,5^2) / 8=205W

Grtz, Joris
