Trace Elliot AH400SMX
This is a great amp
transistor and the amplification is ca fate 350Watt
the connection is a single jack for effects loop baffle Duex

is not very well settle his thanks to the graphic EQ
There is a good compressor that separates the compression of the bass and treble


The configuration is very simple

the sound is very good is not too difficult to obtain. He bcp medium


It should be very good rock and jazz
I play it with an ibanez sdgr886
the sound can vary the lens (thanks to the extreme high) in fat (with a lot of sub bass)


I have now for 2 years and I am very happy
J'aimpe bcp graphic equalizer well extended in frequency

report quality price is right and I do not really hesitate before buying it (it was the stuff sold 70% exposure)

Trace Elliot AH400SMX
I am RAH400SMX, the only difference is that the head is rack (2U)!

- Amplification transistor preamp with a lamp (you can choose from pre-amp between the lamp and the transistor with a knob).
- It delivers 400W in 4Ohm (two HP 8Ohm connected) so in about 250W 8ohm (HP 8Ohm one connected). [Note to self: 400W is really too much, it's no use]
- The connection is extremely full!
- Low Input (with selector Active / passive)
- HP Output Jack or XLR
- 3 XLR DI outputs. A pre-EQ (mono) and a post-EQ stereo (2XLR)
- Effects Loop Mono (2jacks with a button-10dB or +4 dB)
- Stereo effects loop (with a 3jack knob from-10dB to +4 dB on Send)
- Line Out (Left and right) jack
- Exit acordeur
- Input Footswitch
- Settings:
- Input Gain with 3 LEDs to determine the signal strength.
- knob dosing preamp (Lamp / transistor)
- Bonton Shape 1 Shape 2 and two modes that are pre-determined EQ (roughly: a hollow mediums, the other highlights). Button to enable / disable Shapes.
- Figure 12 EQ bands (30Hz, 40Hz, 60Hz, 100Hz, 180Hz, 340Hz, 660Hz, 1.3kHz, 2.6kHz, 5kHz, 10kHz, 15kHz) that can enable / disable with a button that can make + or - effectively using a knob.
- Compressor low frequency (knob)
- Compressor frequency (knob)
- "EQ Balance": a very special knob. Turned to the far left: it was full of bass and infrabass gigantic turned right: there was a lot of treble and high mids with almost no bass. So it's a kind of rough equalization in one button but can be useful for changing the scene instantly.
- Volume
- knob dosing efficiency effects of the loop
- Standby (on / off is behind the amp head)

Note: The fan is super loud, I must find a way to reduce it, especially since at home I rarely play more than one tenth of the volume so it should not heat much the amplification stage.


- Once we understand how it works, the head is easy to use. But it has so many functions that it must do.
- You can not miss his sound given the number of adjustable.
- I did not have the manual but you can find on the Internet. It is not used much.

Note: Above all, do not turn on an amp head when no speaker is connected and obviously do not turn on without a fuse! I screwed up the amplification stage like that! Result: € 290 repair I think. It hurts. Otherwise, it's a really solid head, go for the break.


- I play rock, punk, metal, funk, soul ... and the amp suits all situations that I have a cabinet above 15 "and 2x10" which can play all styles. Although very apreciated rockers, Trace Elliot is extremely versatile, you can play everything with this head!
- I played with a Condor BX-12 (low entry level similar to the Cort Action bass), a Warwick Corvette Double Buck $ $ and one of the 60 Japanese Conrad.
- You can get any sound! It seems to me impossible not to be satisfied.
- I love the sound with great bass and treble as I slapper not bad, there is a huge dynamic!


- I use it for over a year, I had bought used (it must have a good over several decades).
- I love the huge range of sounds that can be obtained. I do not like her weight!
- I tried the Hartke, Ampeg, Markbass. I really liked but it was really expensive Markbass ...
- These heads are no longer selling new, but the price / quality ratio was good and on occasion it is very good!
- I certainly would do if the choice was not as heavy! When she stays with me it is not a problem, but when I do a concert, it's really hot to have to carry everything.
