The QSC RMX4050a 2000W Professional Power Amplifieris a 3RU unit designed for high power live sound reinforcement applications. The amplifier features both XLR and 1/4" balanced inputs as well as Speakon and touch-proof binding post output connectors. The integrated user-defeatable clip limiters and selectable low-frequency filters allow you to adjust the amplifier to your application.

The amplifier is rated at 850W per channel at 8Ω from 20 to 20,000 Hz, 1400W per channel at 4Ω from 20 to 20,000 Hz, 2000W per channel at 2Ω from 20 to 20,000 Hz, and 2800W in bridge mono mode at 8Ω from 20 to 20,000 Hz.

This unit is less than 16" deep and features a three-tier Class H output circuit design for efficient power management. As a result, less AC current is wasted and more available current is utilized for amplification.

Related Questions and Answers

Q: 1. hello it can be connected to a voltage 220?

A: The QSC GX3 operates at 120V AC. You will need to use a step-down transformer to use it with 220V AC such as the Sevenstar ST-500 Step Up/Step Down Transformer - 500W (B&H # SEST500UD) or Watson Voltage Converter - 500 Watt Max (B&H # WAVCGSD500).

Q: 2. How many speakers can I link?

A: The PMXAKB2000 features two speaker connections on the rear of the unit. You are able to use either a banana plug connector or bare wire for connection. More than one speaker connected to each terminal is not recommended.

Q: 3. that work with 700 w speaker?

A: The Pyle Pro 2000W Karaoke Mixer/Amplifier with Bluetooth (BH # PYPMXAKB2000) may work with a speaker rated up to 750 watts @8 ohms. This is a maximum ratinf and not intended for continuous use. Check your speaker's specifications for ratings that are listed as peak, continuous or RMS. RMS would typically be the most suitable and lowest rating.

Q: 4. how do i set the jumpers in back i cant understand the diagram on the back?

A: The jumper settings on the ISA Ti will depend on the mode you are using the amplifier. Switch 1&2 correspond to the limiter and filter for channel 1, switch 9&10 correspond to the filter and limiter on channel 2. The center switches (3-8) set the amplifier mode: Stereo parallel or Bridged. Settings are shown on the rear panel diagram.

Q: 5. CAN i connect 4 speakers 8Ohm 150w rms to each channel in parallel mode ?if not which is the best way to connect 4 speakers/channel, not to overload the machine or burn the speakers?

A: Connecting four 8 ohm speakers to a channel will present a 2 ohm load which the GXD 8 is not designed to handle. A minimum of 4 ohms per channel for proper operation is recommended by the manufacturer.

Q: 6. how many wireless mics can I use with this unit?

A: This mixer has two mic inputs for a total of two wireless microphones.

Q: 7. how much does it weight ?

A: 62.6 lb / 28.4 kg

Q: 8. Can this amp be used in a home theater setup?

A: It can, if your home is sufficiently large. The amp is designed for speakers up to 300W (most home theater speakers don't go above 100W, which would fill a decent sized living room with sound.) So the GX3 would work, but you also may find it overkill (and if your speakers are too small or rated at 16 Ohm, you may blow your speakers if you turn the amp volume up too high.)

Q: 9. Is it possible to output low impedance on channel one and high impedance on channel two simultaneously?

A: When in stereo mode, the QSC ISA300Ti Commercial Power Amplifier with 70V Transformer operates both outputs independently, so you could use one channel for 8Ohm and the other channel for 70V.

Q: 10. Is this compatibly with AV receiver and wireless Mic?

A: It's an AV receiver by itself and wireless mic works when you plug in the mic wireless transmitter. Hope this answers your Q.
