In controlling the F / R SW with voltage source, it is applied as follows;
Forward mode: 0.8V~V17 (RF OUT)
Reverse mode: 0.15V~0.35V
(4) PRE SW
The terminal of PRE SW (pin(18)) should not be applied to higher voltage than V17 (RF out), because ripple
filter circuit supplies the PRE SW circuit with power source. And this terminal can't be connected with GND
line directly, because the PRE SW circuit doesn't operate normally.
In case of preamplifier on-mode, this terminal should be opened or connected with GND line through a resister
(R ≥ 10k).
It is advised to connect a external resistor (R4 = 100~330k) and capacitor (C4≒1F), in order to reduce a pop
sound in switchover between PRE SW on / off mode (see Fig.2). As for the constants, select the optimum one
depending on each a set carefully.
In controlling the PRE SW with voltage source, it is applied as follows;
Preamplifier on-mode: 0.1~0.5V
Preamplifier off-mode: 1.0V~ V17 (RF OUT)
(5) NF resistor of preamplifier
The NF resistor (R = 39k; see the test circuit) should be connected, to reduce a pop sound.
(6) Input of power amplifier
In case that the volume of power amplifier is less than 10k, it can be connected with power amplifier directly
as Fig.3-1. In case more than 10k, it is necessary to insert the coupling capacitor between volume and PW IN
terminal as Fig.3-2. In case that DC current or DC voltage is applied to the terminal of PW IN, the internal
circuit has unbalance and the power amplifier doesn't operate normally.
