Record Amplifier Gain Control
The LA70001 achieves an adjustment-free record current by adding an AGC circuit in the record amplifier block. The
record current can be modified using the following method.
Record current adjustment 2: When left open.
Pin 12 DC level is set to 1/2 VCC (approximately 2.5 V) by an internal bias, and the record current is determined by
Ro1.
Design value: When Ro1 is 1.5 k
, the record current will be 12.7 mA per channel.
Record current adjustment 2: When used.
The gain can be varied by –6.0 dB to +3.5 dB relative to the value set by Ro1 by applying a control DC voltage of
between 1 and 4 V to pin 12.
Note: The technique shown in the figure below can be used to apply a DC level to pin 12. This allows a control voltage of between 1 and 4 V to be applied.
