Video REC AMP Gain Control
The LA70020 eliminates recording current adjustment by adding an automatic gain control circuit to the recording
amplifier. It is also possible to change the recording current with the following methods.
REC-CURRENT-ADJ2 Open
The internal bias forces the DC level at pin 18 to 1/2 VCC (that is, approximately 2.5 V), and RO1 determines the
recording current.
Design values
RO1 = 1.5 k = 16.0 mA (SP) (per channel)
RO1 = 1.5 k = 12.7 mA (EP)
REC-CURRENT-ADJ2 Used
Applying a DC control voltage between 1 and 4 V to pin 18 adjusts the figure determined by RO1 between –6.0 dB and
+3.5 dB.
Note: One possible circuit for applying this voltage is the following, which provides 9 modes between 1 and 4 V.
Hi-Fi REC AMP Gain Control
The LA70020 eliminates recording current adjustment by adding an automatic gain control circuit to the recording
amplifier. It is also possible to change the recording current with the following methods.
REC-CURRENT-ADJ
RO1 determines the recording current.
Design values
RO1 = 1.0 k = 24.0 mA (SP) (per channel)
RO1 = 1.5 k = 16.0 mA (EP)
