Introduction - Design Concept
1. INTRODUCTION
In purchasing the new SM HP6, you have acquired a headphone amplifier of high class that
meets all the demands and requirements of studio and live work. Due to its extensive functions
the SM HP6 is an extremely efficient and universal headphone amplifier. It has been designed
above all as a reference unit for musicians in the studio. The unit features switching possibilities
and a sound quality few headphone amplifiers can offer. The SM HP6 finds widespread applica-
tion throughout the world, in home/pro studios, sound reinforcement systems and in many other
audio fields.
The SM HP6 features a variety of monitoring options: Each of the six stereo amplifiers can
accept signal from any of the four stereo inputs on the rear of the unit. This allows FOUR com-
pletely independent monitor signals to each set of headphones connected to the SM HP6! Ever
had the drummer wanting a different mix feed from the keyboard player? I bet you have, and now
it is finally possible using the SM HP6.
2. THE DESIGN CONCEPT
2.1 High quality components and design
The philosophy behind SM Pro Audio products guarantees a no-compromise circuit design and
employs the best choice of components. The operational amplifiers NJM4580 which are used in
the SM HP6, are exceptional. They boast extreme linearity and very low distortion characteristics.
To complement this design the choice of components includes high tolerance resistors and
capacitors, and several other stringently selected elements.
2.2 Inputs and outputs
All inputs and outputs are secured firmly to the exterior chassis housing. This ensures robust
quality and confidence in performance under all conditions.
