Page 33

Gain Resolution

1.5dB

This is the change in gain between each successive volume setting (i.e. ‘46’ is -1.5dB, ’47’ is 0dB, ‘48’ is +1.5dB). The gain resolution is linear throughout the entire gain range.

Total Harmonic Distortion (THD+N)

<0.004%, 20Hz to 20kHz

Total Harmonic Distortion + Noise is the percentage of output signal which is made up of frequencies added due to harmonics of the fundamental frequency and noise. By using a truly balanced circuit topology throughout the SM6 and maintaining Class A operation at all stages, Perreaux engineers have kept this figure to a minimum.

Frequency Response

20Hz to 20kHz, +0dB –0.03dB

This is the “standard” specification with which everyone is familiar. Actually, “frequency response” is a misnomer: technically, it should be called “amplitude response versus frequency” for it describes how uniform the amplitude or strength of signals of various frequencies is maintained. It is generally thought that a difference of 1dB is the least that can be perceived by ear, the SM6 is specified almost seven times higher, thus exceeding the audible range of the human ear.

Signal to Noise Ratio (unweighted)

100dB

The ratio of desired signal to noise signals present in the output. The balanced circuit topology of the SM6 provides the foundation for high noise rejection. This figure is referenced to the rated output of the SM6, taking into full account all potentially annoying hum components.

Dynamic Range

116dB

Dynamic Range is the difference between the loudest and quietest portions of a signal. Due to CD formats 96dB dynamic range limit, the SM6 provides more than enough dynamic range to cope with any musical transients the CD format can throw at it.

Channel Separation

105dB @ 1kHz

Channel separation indicates the immunity to crosstalk. Crosstalk is caused by stray inductances and capacitances between components and lines, which results in unintentional mixing of stereo signals. Meticulous wire routing ensures excellent high-frequency separation while superior power supply design maintains low-frequency separation.

Input Impedance

10kΩ

The resistance “load” that is presented to the component that is driving it. The high value indicates that the preamplifier will not load down the output of most high quality source components.
