Weight

 

Gross ..........................................................................

2.0kg (4.4lb)

Net.............................................................................

1.4kg (3.1lb)

Rated Power Output (per channel)...................

1.0WRMS into 64Ω

This is the optimum operating level of the unit, offering the best performance whilst allowing a large enough buffer to accommodate the unpredictable nature of music. It is the reference output level to which other specifications, such as sensitivity and gain, are referred. The Rated Output does not indicate the full capability of the SXH2.

Voltage Swing ......................................................................

31.5Vp-p

Loud transients call for a sudden burst of power from the amplifier to drive the headphones. This force is voltage. Peak- to-peak voltage is a more useful specification than Watts when it comes to delivering power to a speaker.

Input Sensitivity ...................................................................

1.45VRMS

The Input Sensitivity figure indicates the input voltage required to achieve “rated” output (1.0WRMS into 64Ω ).

Maximum Gain .......................................................................

15.0dB

The amount of amplification the amplifier is asserting on the input signal. Gain can be calculated by dividing the rated output by the input sensitivity.

Input Impedance.......................................................................

50kΩ

The resistance “load” that is presented to the source component that is driving the SXH2.
