The recording current can be set different for each of the four heads. To perform it the ENVC output is either at low level or high impedance according to the selected head or mode. Then two external resistors with adequate value have to be connected respectively between the ENVC and TRIV and SWM and TRIV, playing so that on the equivalent value of the RADJ resistor. 5/6 5726A-06.TBL SW-R STV5726A PM-SO20.EPS PACKAGE MECHANICAL DATA 20 PINS - PLASTIC MICROPACKAGE (SO) Dimensions Millimeters Typ. 0.1 0.35 0.23 Max. 2.65 0.3 2.45 0.49 0.32 Min.
