AA400 vs CS800
By Kyle from North Shore on 2012-01-05
I sent 2 amps to my brother overseas. 1 Peavey CS800 and AA400. He was amazed that it sounds well and almost the same in terms of sound quality. I hope GMP will have an AA1200 available soon! Good value for money amp.
By Rusty from Auckland on 2011-11-24
Appears to be a solid and well assembled amplifier, with a few details that could be improved upon. Some interior wiring is not well strain relieved and may fail over time if the units are moved a lot (can be remedied with a hot melt glue gun). The input CMRR is poor (less than 5dB).

However the amplifiers appear well heat-sinked, have Japanese ball bearing fans (should be durable), generally meet their advertised specifications and will continuously output their specified power, unlike some competitors.

A value for money product.
Nice Buy

I'm satisfied with the performance. Sounds good and performs well.
Good value for money
By Paiman from Wanganui on 2011-03-14
The AA400 is a perfect match for a pair of Peavey 358s' - 15 inch drivers etc while operating continuous in full range..
At rural outdoor parties, I found that 50-60 volume setting is sufficient in keeping everyone happy on the dance floor
and that the AAA400 has never let me done once while playing
outdoors under shelter. 1 year has passed and I'm still getting
the same volume at each of my gigs.without fail.
Definately 2 thumbs up from this musician.
Very Pleased
By Mick Verified Buyer from christchurch on 2010-11-10
So far very happy with this amp, great value for money. Shipping within NZ was included in the price which is very handy for a 18kg package. Running 2 x 15" 4 ohm speakers off it in stereo mode & they sound great.
great amp

Globalmediapro AA400 Audio Amplifier
By Wayno from Auckland NZ on 2009-05-24
Very well made amp, I have purchased 4 of these now and I am very pleased
with them. Very powerful and it seems the wattage is as stated. I have
one driving 2 x 21" subs , one driving 4 x 15" bass and two driving 4 x
12" Fullrange. At some stage I would like to upgrade to the AA1200 to
drive the subs.. Only downside is they don't have clip indicators, so
some type of limiter is advised, otherwise Excellent value for money!
