When it comes to live sound, performing musicians demand two things: tonal accuracy and volume. QSC RMX 2450 Power Amplifiers are a low cost solution for professional stage amplification, providing top quality sound in a surprisingly small and affordable package. The QSC RMX 2450 is capable of operating in both monaural and stereo modes, making it suitable for use as a stage amplifier for instrumentalists, vocalists, DJs, or front of house systems.

The maximum rated power output of the RMX 2450 is 2400 watts when operating in bridged mono mode, or up to 1200 watts per channel when driving a pair of 2 ohm stereo speakers. It is equally capable of driving 4 and 8 ohm speakers, with an output of 750 and 500 watts, respectively. It provides a tonal response that is nearly flat across the entire frequency range, lending the accuracy that musicians demand out of their equipment. Some musicians may wish to use speakers that are unable to safely reproduce subsonic bass frequencies, however. For these musicians, the RMX 2450 features user selectable 30 Hz and 50 Hz bass roll-off filters. It has an independent roll-off filter for each channel, making it possible for the RMX 2450 to drive a main speaker on one channel, and a subwoofer on the other.

In addition to having some of the best sound quality available, the RMX 2450 is equipped with several safety features that help to ensure continued proper operation of the unit for many years. These safety features include automatic clipping detection, usually found on much more expensive amps. With clipping detection enabled, the RMX 2450 automatically senses when the input load is too high and may potentially cause a blown speaker, reducing the internal volume of the amp to prevent damage. This feature may also be disabled if desired. Along with clipping detection, the RMX 2450 has internal fault protection circuitry to prevent any components from being damaged by a sagging or spiking power supply. These features are combined with an internal heat sink and fan combo, designed to help the unit remain within the proper operating temperature range even under the harshest stage lights.

Any touring act would do well to have QSC RMX 2450 Power Amplifiers in its arsenal. The RMX 2450 is powerful enough to supply adequate volume for nearly any indoor concert venue, and many types of outdoor venues as well. Bands that are still playing in very small locations such as coffee houses, however, may be happier with an amplifier that supplies slightly lower power such as the QSC RMX 850.

* Rated for up to up to 2400 watts in bridged mode, or 1200 watts per channel in stereo operation
* Numerous fault protection mechanisms ensure proper operation under the most strenuous conditions
* User-selectable low frequency filters allow the owner to customize the amplifier's tone to their liking

QSC RMX 2450 Buying Options

There are some performance situations where only the most powerful amplifier will do, and QSC RMX 5050 Power Amplifiers fit that bill. QSC has been providing top quality amplification to professional musicians for over four decades, and the RMX 5050 is the new flagship of the RMX power amplifier line, providing up to 5000 watts of muscle. The RMX 5050 can be the backbone of any touring band's sound system, providing enough power to reach the back rows of virtually any indoor or outdoor concert venue.

The RMX 5050 is a two channel power amplifier, capable of the aforementioned 5000 watts in bridged mono mode, or up to 2500 watts per channel when driving a pair of 2 ohm speakers. With 4 and 8 ohm speakers, the maximum output of the RMX 5050 is 1800 watts and 1100 watts, respectively. This power is provided with minimum waste: the RMX 5050 is among the most efficient amplifiers in the RMX product line. It also provides exactly the same sound quality that musicians have come to expect from QSC products, with a tonal response that is designed to be even from the lowest bass to the highest treble frequencies, for maximum accuracy.

In dual channel operation, the RMX 5050 is an ideal solution for driving both a subwoofer and main speakers, thanks to its independent bass roll-off filters. For each channel, the owner can set the roll-off filter at 50 Hz, 30 Hz, or off. This allows for maximum protection of speakers that can not reproduce subsonic bass frequencies, and minimum crosstalk when a standard speaker and subwoofer are used in tandem.

Along with top of the line sound quality, the RMX 5050 features several safety mechanisms to ensure proper operation even in less than ideal conditions. Its automatic clipping detection feature senses when clipped waveforms are entering the amplifier (due to input volume that is too high), and automatically reduces the internal volume of the amp to prevent permanent damage from being done to the speakers. Clipping detection can also be disabled if desired. Additionally, the unit features direct mounted internal heat sinks and high power cooling fans, ensuring that proper operating temperatures are maintained even during all day events.

For musicians that demand the most powerful amplifier and highest quality sound in one package, QSC RMX 5050 Power Amplifiers are the ideal choice. With the RMX 5050, QSC has managed to provide one of the most powerful amplifiers on the market, while maintaining the tonal quality that they are beloved among musicians for - all in an affordable package that won't break the bank.

QSC RMX 5050 Power Amplifiers - Summary:
* Rated for up to 5000 watts in bridged mono operation, or 2500 watts per channel when driving two speakers
* Industry leading fault protection ensures that the unit can withstand strenuous road conditions
* Adjustable bass roll-off filters provide speaker protection and a customized tone
* Three year factory warranty, can be extended to six years after purchase

The RMX family of power amplifiers, produced by QSC, has been among the top product lines in the industry in terms of performance for cost, since their introduction. QSX RMX 1450 Power Amplifiers represent the intermediate power amp in the RMX line, with higher wattage than the entry level RMX 850, and lower cost than the RMX 2450 and other more expensive models.

The RMX 1450 has a maximum power output capacity of 700 watts when driving a pair of 2 ohm speakers, and bridging the amp and putting it into single speaker operation ups the total to 1400 watts. The RMX 1450 offers a signal to noise ratio rivaling that of most studio power amplifiers, at 100 dB, with less than 0.01% distortion. It features a tonal response that is almost completely flat across the entire frequency range. This results in some of the most accurate reproduction of sound possible in a power amplifier intended for live performances.

The road can be extremely harsh on professional audio equipment, but the RMX 1450 is built to last. It includes internal cooling fans designed to keep the unit operating within the correct temperature ranges, and multiple levels of protection against electrical faults. Additionally, it includes automatic clipping protection, which the owner can enable or disable as they please. When clipping protection is enabled, the RMX 1450 automatically detects when the input level could potentially damage the loudspeakers that are attached, and lowers the volume accordingly to ensure that a speaker is not blown out.

Further customizing the experience are two independently controllable filters - one for each channel of amplification - that allow the bass response of the RMX 1450 to be rolled off at either 30 Hz or 50 Hz. This allows the user to protect loudspeakers that may be unable to handle subsonic frequencies, and create a more customized tone that is impossible to achieve with many competing power amps.

QSC RMX 1450 Power Amplifiers are a highly recommended purchase for musicians or DJs who frequently perform at smaller indoor venues such as clubs and small to medium sized concert halls. For outdoor engagements, or shows at larger auditoriums, it would be advisable to use more than one RMX 1450 in tandem, or consider a more powerful amplifier such as the RMX 2450 to produce adequate volume levels.

QSC RMX 1450 Power Amplifiers - Summary:
* Rated for a maximum output power of up to 1400 watts (mono, bridged) or 700 watts (stereo, 2 ohm loudspeakers)
* Designed for a flat tonal response, resulting in some of the most accurate sound reproduction available in a power amplifier intended for live performances
* The addition of user selectable filters at 30 Hz and 50 Hz protect speakers that are unable to be driven at subsonic frequencies and create a fully customizable tone for specialized operations
* Solidly built; able to withstand harsh road conditions
* Automatic clipping detection to protect speakers; can be enabled or disabled at the owner's discretion
