Everything you need!

Awesome board. I work at an event production company, and we have many boards, both digital and analog, ranging from $100 boards to $50k. This board is truly EXCELLENT. The preamps are very transparent, the EQs are well set up, the mode switching makes it very versatile (I like to run aux fed subs). I would say it tends to excel more with bands that we run than A capella groups because it's eq section is very sensitive. In the noisy clutter of a band, a bigger adjustment does just the trick, but for tweaking the EQ to 6 individual voices, one must be very careful in making even a small adjustment with this EQ section.

This is an Outstanding Mixer

Bought this from Sweetwater on Monday and it arrived the next day for a truly speedy delivery. Worked with Chris and Justin on the purchase. Bought the dust cover and Litt lite LED lamps to illuminate the board during low light conditions. We were in a desperate situation at our Church having continuing issues with our old mixer, a Yamaha 32/14fx board and Easter services approaching on Thursday, 2 days away. Our old board had been around for 7-8 years and was popping and cutting out at all the wrong times forcing some musicians to unplug due to sporadic feedback. After much online research, my choices came down to Allen & Heath and Soundcraft. Decided to go with the Allen & Heath due to great reviews, reading about other Churchs using Allem & Heath and availability with Sweetwater. Absolutely no regrets getting this board! Being a novice to mixing, I brought in an audio engineer to help me adjust the sound at our Church and go through our system. We completed the install and component adjustments on Thursday @ 5:30 pm and were letting Parishners in at 6:30 pm. We have a Great Choir, but no one really new how good until we installed this board. At the end of services, we actually had people come up to us with tears in their eyes thanking us for the music. Each service ended in loud applause. It was truly a moving experience for Easter 2012. Folks came up and thanked our audio engineer, Matt and myself for making it all happen. I would recommend this board to anyone needing clean sound as the mic pre-amps are amazingly clean and warm. Our Church sound system now sounds truly amazing thanks in large part to this board. Absolutely the best purchase I have made regarding sound equipment! NO Regrets!

No Comparison

The Mackie will do the job well as long as you don't work the EQ's too hard, but they don't travel well. It is not a better value. My GL2400-24 is pristine and has never let me down. Even after hundreds of gigs, it sounds great and has had no problems, not even so much as a noisy pot or fader!

Fantastic Mixing Console!

I've been using this board for 2 months now, and love it. The board has features that can be applied to almost any setting, and definitely a great studio mixing console, which is what I am using it for. I really don't have any negative things to say about the GL2400-24. I would definitely recommend this console if you are thinking about purchasing it.

Sweetwater Advice

Evan Mehre

Having used this board for everything from bands to corporate functions, I can appreciate its warm and clear preamps and musical yet powerful EQs. It's also incredibly durable. We had a soda line for a vending machine break above this board, and fill the console to the brim with soda. It took a week to dry out, but nothing was damaged, and the mixer is still working perfectly a decade later.
