    I use Apple Airplay for all my audio. This done via an Airport Express for each zone with a 3.5mm out to RCA in on the amp. Volume is modulated via the Airport Express- and thus the input signal to the amp. This means the amp's volume needs to be set at the highest I'd ever want all the time. At extreme low volume (airplay turned way down), I'd like any humm to be minimal. Will the XMP300 humm in this application? Also, I see the XMP300 has signal sensing to turn it on - will it go back into standby when the input signal stops? This setup will be used with your outdoor 850 speakers.

    Hi John: There should be no issue with a hum from your setup. And the autosensing wakes up when the Amplifier sees a signal present. After the signal shuts down, it usually takes 15 minutes before the Amp goes into standby mode waiting for the next audio to be present. Note, Make sure you use a well-built 3.5mm to RCA Adaptor cable. The AMP300 and AP850 are a great match. Also, the AMP300 is 4 ohms stable so you can add a second pair of AP850 to Speaker B and both (speaker A and B) can play at the same time. Good choices TL/5442

    I’m looking to upgrade an undersized 100W amp to power a 6-zone speaker selector with impedance selector for (12) 8-ohm speakers. My cabinet has some ventilation but tends to get hot with a class A/B amp. It looks like the AMP300 would work but I’m concerned it may get too hot. This XMP300 looks like it has less power than the AMP300 (unless I use it in bridged mono) but I’m concerned it may not provide the same sound quality. Thoughts?

    HI Mark: The Specs on the XMP300 are similar to the AMP300. The AMP300 is a High Current Amplifier that has High Power Toroidal power supply plenty of internal capacitance and ample internal heat sink (the amp weights 35 pounds). It is a High Current Amplifier that is 2 ohms stable and is based upon a 30 year Class AB design. Having said that the XMP300 has the same identical specs for 8 ohms (150 watts), 4 ohms (235 watts) but is a class D design that has a high power digital power supply that is 93% efficient (versus 50% for typical class A/B design). I believe you will have no issues with for your application utilizing the XMP300. Note, the problem with Bridging two amplifiers (either the AMP300 or the XMP300) it is critical the amps see an 8-ohm load. And not recommended when driving multiple speakers through a speaker selector. Good luck TL5348

    Can this amp be used to power multiple zones in a full house audio system? How many zones can it handle?
    1 Answer
    Hi Rodney: Yes, this amp can be used to power a multiple-room system. The number of rooms depends on the choice of speaker selector and whether you plan on using Impedance Matching Volume Controls. We have speaker selectors with and without Impedance matching Volume Controls built-in. We have speaker selectors for 2 to 12 zones. Would probably limit this amp to 6 zones using our DSM6 along with SVC300 Impedance matching Volume Controls of our SSVC6P with Impedance Matching Volume Controls built in (one VC for each zone). Let me know what you are planning so I can help with your setup. We have available every option for basic Multi-room systems. Your Plans TL/5218
