bridged crown xls serie?

Pertti

Hi
DRPA system setup don't accept low amp bridging mode with crown xls serie, why?.
i want to use my xls402 with my mono sub,
i tried many different combinations.
every other pre programmed amp works fine.

Best Regards

I have a hunch. What is your exact cab / amp set-up?

Hi DRA
thank you this quick response,
i know, you need more information

1 pcs. xls402 -> 2 pcs. 12\"/1\" top,
200W RMS, Celestion drivers, xover 1.8 kHz, 100 -> Hz,

1 pcs. xls402 -> 1 (2) pcs. 15\" sub,
500W RMS, PAS HL-2580C driver, 35-100 Hz

all these speakers are custom made,
i use this set at live club/pub/small venue.... gigs,

You said, \"1 (2) pcs. 15\" sub\"

Do you have one 2 x 15\" or two 1 x 15\" subs, or something else?
Either way, that's a 4 ohm load and the XLS series can't bridge to 4 ohms.
Even if you only have an 8 ohm sub and assuming that you entered custom as your speakers, the DRPA assumes (260 GUI wizard shows a dual cab, which implies a 4 ohm cab) that you have a 4 ohm sub and the XLS can't do it, so it isn't offered to bridge. If you can clarify, I can offer a suggestion. However, the wizard doesn't really do you any good anyway. You need to go to the \"READ ME FIRST\" section, and read everything there. It will help you a lot.

now i try to use one 1x15\" 8 ohm sub,
i have been \"READ ME FIRST\" section, and read allmost everything there,
and i understand allmost everything what i have to do,

by the way xls402 factory box include 4 ohm bridged power:
\"BRIDGE 4 ohm 1140W\" is this some kind of rip-of marketing gimmick?
i always think that CROWN is very respectable company, do i have to chance my opinion :shock:

The XLS series will do 4 ohm bridged no problem, and 2 ohm stereo although I don't like 2 ohm loads.

From the Crown website:

XLS Series


Minimum Guaranteed Power XLS 202 XLS 402 XLS 602 XLS 802
per channel, both channels driven
1 kHz with 0.5% THD
Stereo, 4 ohms (per ch.)
Stereo, 8 ohms (per ch.)
Bridge-Mono, 8 ohms

People don't usually under sell their equipment. But, you never know. Seems like these stats would make people shy away.

how about my original problem, can you help me,
or is it better if i do all setups manually?
anyway, this is amazing site, thank you

Dra

You should do it manually, regardless.
But if you wish to \"show\" the XLS402 as bridged, don't select the speakers as custom. Select as your top speakers the Yamaha club S/C112V and sub as Yamaha club S/CW115V.

Give that a try.
