  1. Thanks for the response, Rod. I noticed on the back of the unit next to the power plug it says "200 W". What does that refer to? Based on the 12A circuit breaker limit, the amp could draw as much as 1440 Watts of power. Thanks again!
  2. What is the amperage rating of the XLS1500 circuit breaker? US/120V version, if that matters.
  3. Well, the XLS 1500 came today and I got it hooked up. It works great and gets plenty loud for my needs. Thanks everyone for the help!
  4. Is it a big "no no" to connect in parallel two speakers that are of different nominal impedance? One is 8 ohm while the other is 6 ohm?
  5. On a second thought, I could just forget about the HK's internal amp and power both sets of speakers with the XLS I guess.
  6. Yeah, this HK receiver is a bit different. In normal operation (no external amp connected), its pre-out and main-in connections are linked together with two jumpers (see pic). In order to be able to connect an external amp, I have to take the jumpers out. When you take the jumpers out, the HK's own internal amp will not be receiving any signal anymore unless you close the loop again and bring the signal back to its main-in connections.
  7. One other question though: After I send the signal from HK to the XLS, I will need to bring that signal back to the HK to close the loop and allow the HK to power some speakers, too. I was thinking of doing this by utilizing the unused 1/4" connectors on the back of the XLS and using a 1/4"-to-RCA cable to bring the signal back to the HK. This will only work if the XLS just passes the signal "as is". But if it amplifies that signal to pro-audio levels before sending it out the 1/4" jacks, then this signal will be too strong for my HK. Alas, as far as I know, these 1/4" connectors on the back of XLS are just pass through. There is no amplification going on there. Am I right?
  8. No, it was just a regular multimeter. Worst case scenario, I'll have to pick up one of these balanced/unbalanced converters to boost the signal. Thanks!
  9. Well, I just checked the manual for that unit and it says the pre amp output is only 1V and that's not enough for full power... better get a pro audio pre amp or mixer to drive the amp. After reading this and doing my own measurements, I'm not too worried. I won't really require anywhere close to this amp's full power anyway. The speakers that I have may not be able to handle it either. By the way, I'm pretty sure that 1V output level that you found is for video pass-through signal. HK doesn't actually provide this value for the audio pre-outs, or at least I have not been able to find it.
  10. Thanks! What pre-amp/receiver were you using to feed the XLS? As far as the bright display, it really will not be an issue in this particular setup. But I remember in my previous setup I used to have a Behringer Feedback Destroyer with very bright orange display. I slapped on a couple of layers of dark window tint on it and that tamed it nicely.
  11. The feed will come directly from my stereo receiver's pre-outs (HK 3490). I was doing some measuring the other day and at full volume, it outputs 8.5V. Figure about 4V realistically, before distortion starts kicking in. I was hoping this would be enough to feed the XLS and still get reasonable volume.
  12. Is something like XLS 1500 DriveCore suitable for regular home audio duty? I've got a stereo receiver (HK 3490) and 4 speakers in the basement (Jamo C603 and Polk Audio M40). That receiver is struggling a little with all 4 speakers at good volume. I was thinking of adding an XLS 1500 amp to drive two of these speakers. The XLS appears to have abundance of power at 8 Ohm giving me lots of headroom, but I'm not sure what it's like from sound quality perspective. Anyone know how the sound quality would compare to a traditional amp but with half the power, such as AudioSource AMP310? My only experience with Class D amps in home audio is with a Panasonic A/V receiver that I've had since about 2007. This one's actually sounding pretty good. Thanks!
