Page 10 Model PA1235X
© 2002 Xantech Corporation.
PA1235X can be switched ON and OFF via the switched AC outlet on the rear of a preamplifier. When the
preamplifier Power Switch is switched ON, power is applied to the DC adapter, which in turn applies 5V to 30V
DC to the PA1235X, switching it ON. Similarly, when the preamplifier is switched OFF, the DC voltage to the
PA1235X is removed, turning it OFF.
