QSC amplifiers, good for HT use or overkill?

[}Fear_Inoculum{]

I came across a used QSC RMX-2450 for sale for ~600$ Canadian Pesos. (The same place also has a used RMX-850 for ~350$)

Are these amps good for HT/AVR use, or are they complete overkill and better suited to professional music use?

I use pro amps (Crowns). I'd use a QSC any time, tho. The only consideration is does the connectivity match up to your needs and possible fan noise (I don't know about these QSC). Ask @Verdinut how he likes his QSC (different series, DCA if I remember correctly). Can be a greater value than consumer amps and with a better feature set....but the boxes tend to be on the fugly side

• Amplifier Output Details
  450 Watt - 8 Ohm - 20 - 20000 Hz - THD 0.1% - 2 channels (main)
  500 Watt - 8 Ohm - at 1 kHz - THD 0.1% - 2 channels (main)
  650 Watt - 4 Ohm - 20 - 20000 Hz - THD 0.1% - 2 channels (main)
  750 Watt - 4 Ohm - at 1 kHz - THD 0.1% - 2 channels (main)
  1200 Watt - 2 Ohm - at 1 kHz - THD 1.0% - 2 channels (main)
  1300 Watt - 8 Ohm - 20 - 20000 Hz - THD 0.1% - 1 channels (bridged)
  1500 Watt - 8 Ohm - at 1 kHz - THD 0.1% - 1 channels (bridged)
  2400 Watt - 4 Ohm - at 1 kHz - THD 1.0% - 1 channels (bridged)
• Response Bandwidth : 5 - 50000 Hz
• Total Harmonic Distortion : 0.02 %

• Nominal Voltage : AC 100/230 V
• Frequency Required : 50 - 60 Hz

• Input Channel Qty : 2
• Input Impedance : 10 KOhm
• Input Sensitivity : 1.23 V

• Output Power / Channel : 1200 Watt, 1300 Watt, 1500 Watt, 2400 Watt, 450 Watt, 500 Watt, 650 Watt, 750 Watt
• Output Impedance / Channel : 2 Ohm, 4 Ohm, 8 Ohm
• Frequency Response : 20 - 20000 Hz, at 1 kHz
• Total Harmonic Distortion (THD) : 0.1 %, 1.0 %
• Channel Type : bridged, main
• Channel Qty : 1, 2

CONNECTIONS

• Qty : 1, 2
• Type : audio input, balanced audio input, speakers output
• Connector Type : Speakon, XLR x 2, banana/spade x 2, phone stereo 6.3 mm x 2, terminal block (clamp)

I'm assuming that the connectors would work fine for my AVR & speakers.

I think QSC mostly caters to musicians and not so much to HT.

Well this unit doesn't provide for the unbalanced/rca connections your avr has (at least I can't think of any avrs that offer balanced pre-outs, altho some pre-pros do), but rather has XLR and 1/4" balanced inputs. My Crowns have consumer-friendly rca inputs. You can use a converter cable, tho keep in mind sometimes issues can result from the mismatch.

ps remembered one avr with L/R balanced outs, the Yamaha 3080....

QSC also supplies cinemas and other venues worldwide with their DCA series of amplifiers, DSPs and loudspeakers:
