QSC RMX 1450 Power Amps Review

Posted by admin in QSC on August 4th, 2009

QSC RMX 1450 Power Amp 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.
