Overall Dimensions
Width	216mm (8.5”)
Depth	178mm (7.0”)
Height	58mm (2.3”)
Weight
Gross	3.0kg (6.6lb)
Net	2.4kg (5.3lb)
Rated Power Output (per channel)	25WRMS into 8Ω

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 SX25.

Voltage Swing

55.2Vp-p

Loud transients call for a sudden burst of power from the amplifier to drive the speakers. 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

0.63VRMS

The Input Sensitivity figure indicates the input voltage required

to achieve “rated” output (25WRMS into 8Ω).
Gain	27.1dB

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

40kΩ

The resistance “load” that is presented to the source component that is driving the SX25.
