Designed to be gigged hard the Mackie SRM450 V3 Complete PA Package offers relentless power, professional effects and all the stands and cables needed for connection. Be you in a band, a DJ, singer or entertainer you can be sure that you are getting a premium PA system that will get you sounding at your best.

Mackie SRM450 Active Speakers

The Mackie SRM450 V3 2-Way Active Bi-Amplified Loudspeaker is packed with a 12-inch high-power low-frequency woofer, which is paired with a 1.75-inch titanium diaphragm high-output precision compression driver. Each driver has been designed by Mackie's expert engineers to perform exceptionally across the frequency range, encasing each one in a lightweight high-strength cabinet for protection. The drivers have an operating range across the horizontal axis of 90 degrees, and 45 degrees across the vertical axis, which means that whether your listeners are stood close to the speakers, or off to the side, everyone gets the same aural pleasure.

Bi-Amped Power

Mackie's design team has equipped the SRM450 with a pair of amplifiers that power each transducer exclusively, contributing to the SRM450's low power usage and maximum efficiency. They are Mackie's FR series amplifiers, which are designed to cope with extreme signal output to handle the most demanding of sound sources. Each amplifier has an individual compressor circuit, which acts when the input signal is large to cause clipping, distortion, and excessive voice coil heat, at which point the signal is attenuated to a manageable level.

Mackie ProFX8v2 Professional 8 Channel Mixer With USB

Boasting eight channels for you to play with, the ProFX8v2 features four Mackie Vita preamps, which provide incredibly quiet signal routing that makes them perfect for real-time live sound applications. Pushing them at full-pelt is no problem for these beauties, responding sweetly to both dynamic and condenser inputs, whilst offering 48 VDC phantom power to all mic channels simultaneously.

As well as the mic inputs, there is a range of balanced and unbalanced 1/4-inch inputs, as well as a Hi-Z input that allows you to directly connect a guitar, bass, or other high impedance instruments.

Mackie ReadyFX

Built into the ProFX8v2 is the ReadyFX digital effects engine, which gives direct access to 16 awesome reverbs, delays, and choruses that enable you to give any performance the lift it deserves. The control interface allows you to easily dial in the desired effect, which is indicated on the LCD display.

Built-In USB Recording and Playback

Mackie has included a USB port on the ProFX8v2, which allows recording to be sent directly to your DAW of choice for rapid capture during live and studio performances. There are subgroups available, or you can elect to go for a direct stereo Left and Right mix. There is a separate USB input level control for attenuating the signal during playback. Whether you’re at a party, at a gig, or in the studio, you can quickly playback tracks you’ve recorded with ease. There is also a “Break” switch that mutes all channels so that you can easily switch between playing music and routing the channel inputs.

Stands and cables

The Mackie SRM450 PA Package comes with a durable set of PA speaker stands from Essentials with a black aluminium finish. Great for getting the most out of your SRM450 series speakers the stands can be adjusted from 1m to 1.85m. With a maximum load capacity of 40kg per stand, they can also accommodate a wide variety of speakers. Includes a protective bag for convenient transport.

Finally, a pair of 10 metre Stagg XLR to jack cables are supplied so that you can position your Mackie's wide apart for the optimal sound in the venue.
