The TOA P-906A and P-912A Power A m p l i f i e r s deliver up to 60
watts and 120 watts of power r e s p e c t i v e l y at less than 0.5% total
harmonic distortion (THD) f r o m 20 to 20,000 Hz ( t r a n s f o r m e r l e s s
4-ohm output). The P-906A and P-912A have a high-impedance
d i r e c t input and an input port (edge c o n n e c t o r ) to accept one
module a c c e s s o r y . Module s e l e ction is determined by application
