Input voltage

*1. This item represents values of maximum input signal amplitude in which the output distortion rate shown in the condition column is filled. When the

signal amplitude that exceeds this specification value is input, the output distortion rate is deteriorated. When using this device, the input signal level

should be set not to exceed the standard value of the signal amplitude.
