Bass amplifier transistor preamp tube (1 x 12AX7)
-The power is 500W in mono 4ohms and 250W per channel into 4 ohms in stereo, the manufacturer does not signal down the impedance of the speakers at 4 ohms in mono and 2 ohms per channel in stereo.
Model-type "Rack-mount" black color with red decorations .. registrations are in white on black background, so easy to read (good for dark areas). It is light. The fact that "rack-mount" it requires special care for transportation if you do not put in a "road case" to prevent scratches.
-This amplifier has most of the main characteristics desirable for a bass amp: passive or active inputs, gain, saturation Led preamp, parametric + Bass and Treble, Effects loop, direct out-box with potentiometer aural enhancer, Speakon speaker jacks or 1 / 4 "(6.35 mm) etc. ....

UTILIZATION

Very easy to use, as long as it is known how a parametric Eq.
-The sound is of very good qualities and very changeable.
-The manual (English only by 2005, but no more than one language available on the website of SWR since summer 2005) is clear and very well done.

SOUNDS

-The power of 500W into 4 ohms is adequate and the sound quality is constant as long as one has not reached the saturation level of the preamp (the LED on continuously) ...
-The sound is sharp and defined, but using a tube preamp gives it a little heat (round) ... The more you use the speakers with a large diameter, the more the sound is "fat". I love the sound of this amplifier. All speakers to use with this amplifier has 10 "(25 cm) and 15" (38 cm) has an impedance of 4 ohms and 700W power handling over. I use it with Fender Precision Bass 4 strings.

OVERALL OPINION

-I bought used in 2004-The only thing I regret in this amp is the absence of crossover built (unlike its predecessor, the ST-220) SM A-500 nine to sell $ 1,500.00 CDN (1075 Euros) in Canada in 2005. I highly recommend this amplifier. No other transistor amplifier I have tried never made me regret my SWR.
