When BST = VCC
The EQ can be bypassed by connecting the BST control pin (Pin 19) to VCC. In this case only the EQ block enters sleep mode and the low power consumption mode (slim mode) is activated. The low-frequency gain is the same value as for EQ ON mode. The RF_SUM input dynamic range is VC 300mV (typ.). If RF (summing signal) is present at the pickup output pin, input the addition output signal to the EQ_IN pin (Pin 3) coupled by capacitance. When using a pickup without a summing output function, perform addition with the AC SUM block and then input the signal to the EQ_IN pin coupled by capacitance. RW/ROM switching is done by the VCA block, so either input method can be used without problem. The RW gain is 12dB higher than the ROM gain. The VCA low-frequency gain can be adjusted by the RFG pin (Pin 18) voltage. The control voltage vs. low-frequency gain characteristics are shown in the graph to the right.

The RFAC pin (Pin 13) is an NPN transistor emitter follower output. The maximum drive current is approximately 2mA. If the load capacitance distorts the output waveform, increase the drive current. Connect resistance between Pin 13 and GND. - 11 -

* EQ The diagram to the left shows the EQ internal block diagram. The EQ consists of a combination of HPF and LPF. The HPF and LPF transmittance is the Bessel function. The boost gain can be adjusted by adjusting the HPF gain. The boost frequency is adjusted by the RFC external resistance value and the VFC control voltage value. RFC resistance value: The cut-off frequency fo of each filter is adjusted by the Pin 21 external resistance value. The VFC voltage can be varied using this fo as the reference. VFC voltage: fo can be changed by the voltage applied to Pin 20.

Notes on Operation Stabilizing the RFAC signal The RFAC system (RFSUM + EQ) is comprised entirely of non-inverted function blocks. This is in order to support pickups with built-in RFSUM. Therefore, if the voltage gain of each block is increased, a feedback loop is formed over the entire RFAC system causing the RFAC signal to become unstable (oscillate). In these cases, it is recommended to lower the EQ frequency response and the boost gain. This has a large effect on the board (power supply, I/O signal cross talk, etc.) loop. The RFAC signal easily becomes unstable if the VCA gain is increased, the EQ boost frequency is set to a high frequency, the EQ boost amount is increased, etc. The VCA gain is low in ROM mode, so the RFAC signal is stable. Also, when not using RFSUM, the RFAC signal is stabilized because the overall gain is low. The area where the RFAC signal becomes unstable is thought to vary for each set, as this is greatly affected by the board loop as noted above. Proposed stabilization measures The board and other loop characteristics can be changed by adding external capacitance as noted below. This has a particularly large effect on the stabilization when using RFSUM.
