If it is wished to view or measure the signal across the

load, a floating monitor must be used - for example a

differential probe. Alternatively this may be achieved

with a two channel oscilloscope monitoring the

speaker A and speaker B outputs, and using the invert

and add functions. For diagnostic purposes, the

speaker outputs can be monitored single-ended with

respect to ground with an oscilloscope (or other

instrument) if desired. However any results obtained in

this manner, are not valid for assessing performance.

The true performance depends upon some differential

cancellation across the speaker load.

The board requires an input signal of 2.5V peak to peak

nominal to yield the full output power. The input

impedance of the board is nominally 18k . This may

attenuate the source voltage and may need to be

allowed for, depending on the output impedance of the

source.

The maximum supply voltage to the ZXCD50STEVAL

evaluation board is 25V nominal. A supply voltage of

25V will achieve 50W music into a 4

load.
