Stereo amplifier system for guitar, lamps 2x20 watts.
Each side is equipped with a 1/2 12AX7 pre-amp signal, a 12AX7 as a driver for a pair of EL84 Push-Pull rise sauce Mesa-Boogie.
The connection is simple, by hand, we find an entrance, a slave output allows the recovery of pre-amplified signal to external treatment (super direct box lamp), 1 output 8 Ohms, 4 Ohms output 2.
The front panel always by hand, a volume control and a presence control (sort of light booster - the compressor effect against acute-reactive).
For the management of power, we have a switch and the classic "Stand By" necessary to preheat the lamp filaments.
This unit is 11 kg in the form 1U rackmount, the black finish is the most beautiful effect (there was a series Aluminium finish, but very few copies were imported).
The construction is a rock solid, nothing that the front impresses by its thickness. You will notice that its depth is about 32 centimeters (excluding pots), which can be a problem when it is placed in a rack.
Note also a hidden switch in the receptacle designated for lamps, side V1-V2, to isolate the chassis of the earth. This is very handy for hunting buzz due to closures of various masses. Beware, however, at least one of the devices in a rack system must always be grounded otherwise the risk of electrocution. A thought ...

UTILIZATION

Side configuration, there is nothing easier! it connects the preamp outputs to the inputs of the amplifier (called AB and not left-right), two loudspeakers are connected to the outputs suitable compatible (4, 8 Ohms), switching power 1 minute later and the Stand By .
The sound is powerful, muscular and extremely dynamic. We immediately recognize the leg majestic Randall Smith, Master ES Mesa-Boogie, Boogie all designer since the late '60s.
I readily admit not being objective, few manufacturers have been able to approach the perfection of a tonal Boogie. Connected to speakers of questionable quality, this amp havoc, the sounds are thick, overdriven sounds remarkably accurate.
An interesting test for the most reluctant would connect a guitar directly to the input of the monster. It was the "Sound" instantly.
The manual is available in English (on the manufacturer's website), but the illustrations are numerous and can be coupled quickly and efficiently, all modules of the rack. Spare parts are perfectly nomenclaturées will make it easy to contact the manufacturer on its website.
Personally, I've owned many Boogie without any reliability issues.



SOUNDS

This amplifier is capable of adapting to all styles of music without limitations no.
To my knowledge, there is no equivalent on the market as effective. Also, when making this choice, it must be done in the long term because the amount to pay is not negligible.
Responding to the precept "The quality and efficiency of the system is less than or equal to the worst part of the product," I made a rack around this amp, preamp with the Triaxis brand, a G- strength and TC Electronic M2000, all connections are wired MOGAMI.
In fact, I do not use the reverberations of G-Force, not that they are bad, quite the contrary, but to counteract the latency induced by programs too loaded machine resources when switching the MIDI .
This may seem high, but this is the price to pay for a universal sounds as diverse and varied as the situations require.
I spent hundreds (thousands) of Euros additional equipment purchases other brands thinking to save money, but by dint of buying and selling without stopping, I lost irretrievably money.
I really like this amp, everything is serious, lamp bases are ceramic is hand built (open the top cover of the Two-Twenty to realize the beauty of the wiring) is reliable and, above all, the sound is right there.

OVERALL OPINION

2:20 I use this since September 2002, he took over a Boogie Simul-Class 395, too strong and heavy for the size of the training rooms and with-in which I played.
Before that, I joined the Marshall 2x100 watts, then the smallest 2x50 watts, and finally the even smaller 2x20 watts. I've never been satisfied!
Even today, I am surprised at the tremendous power that this "small amp" can generate. If it is connected, like mine, with baffles "Thiele" brand (equipped with Electro-Voice EVM 12L, now abandoned), the result can be deafening.
Anyway be careful of potentiometers volume, your ears may not recover.
I see only the positive side, this amp will restore your system with loyalty, its relatively small electric power is not a disability, the proof is the resurgence of very low power amps, many on the market.
Finally, you can connect 4x12 (16 Ohms) on the output of this monster without any problem, I think 4 Ohms outputs are more effective than 8 Ohms (question beatings and pain). The amp will work perfectly, it will heat less, but provide less power. The result will sound devastating, since the acoustic pressure is multiplied by the number of HP in motion. A great moment of fear ahead! ...
Hat Netherlands, Mr. Smith!
