In Topic: 8 ohm amp, with 2 different ohm subs

03 August 2016 - 07:53 PM

First, amps have no ohms per se.  They are rated to operate in some given ohms range speakers.  Most pro amp will support 8, 4 or 2 ohms loads, but 2 ohms is very taxing for the amp.

So, in your case, you could run one sub to channel 1 and the other sub to channel 2 somewhat safely, but watch for overheating if you need high output.

Hello.  You could try another set of speaker cable, then another set of speakers if you have some, to assess than it's not a problem outside of the amp.  Then, use a voltmeter to check if the voltage is droping too low when the amp is used.  However, the 8 ohms being an easy load and this amp being so efficient, I cannot see how the voltage could drop that much.

If the issue continue with other equipment and the voltage stays OK, then I think the amp should be serviced.

In Topic: XLS or XTi for hi-fi use?

I'm pretty sure the XLS uses A/D all the time, as it's part of the DriveCore process, DPS bypassed or not.  Crown call A/D the "codec".

This is a forum about Crown power amps.  You'd have a better chance of help on some Sony amp forum for your unit!

In Topic: XLS Series 2 Amp Trigger / Sleep Connection?

I guess I don't understand the issue.  Is the amp visible from your HT viewing position?  Pro amps have different needs than home audio.  LEDs and displays have to be clear and bright to be easilly seen, even outdoor.  They may also have (sometime) loud cooling fans, which is irrelevant in a pro setting.

I have cured all this by placing my amp rack in the basement.
