EQP5 alternate frequencies
Note: Mods are not supported! Once you start modding, we cannot offer troubleshooting support. Make sure your unit is working in the stock configuration before adding any mods.
All the frequency bands on the EQP5 Passive EQ can be customized by changing the capacitor value.
LF- Frequencies
Change these caps:
- C20 for switch in
- C21 for switch out
Frequency | Cap Value |
---|---|
10Hz | 150nF |
20Hz | 82nF |
30Hz | 39nF |
40Hz | 27nF |
60Hz | 18nF |
90Hz | 10nF |
120Hz | 8.2nF |
150Hz | 6.8nF |
LF+ Frequencies
Change these caps:
- C22 for switch out
- C23 for switch in
Frequency | Cap Value |
---|---|
10Hz | 4.4uF (2.2u + 2.2u)* |
20Hz | 2.2uF* |
30Hz | 820n |
40Hz | 560n |
60Hz | 390n |
90Hz | 150n |
120Hz | 82n |
150Hz | None (only the 150nF from C24) |
HF- Frequencies
Change these caps:
- C18/C19 for switch out
- C17/C17b for switch in
C18 and C19 are in parallel to achieve 136nF (which is not a regular cap value) for the stock 10kHz frequency. So to customize the "switch out" frequency, remove C19 and change C18 to the value from the chart below.
C17b is just an extra socket in parallel with C17, in case you want to choose an eccentric frequency or set the "switch in" frequency to 10kHz.
Frequency | Cap Value |
---|---|
3kHz | 330nF |
5kHz | 220nF |
8kHz | 150nF |
10kHz | 136nF (68n + 68n) |
12kHz | 120nF |
15kHz | 100nF |
18kHz | 82nF |
20kHz | 68nF |
HF+ Frequencies
Change these caps:
- C16/C16b for switch in
- C15/C15b for switch out
Frequency | Cap Value |
---|---|
8kHz | 8.2nF |
10kHz | 5.4nF (5n + 390p) |
12kHz | 3.9nF (3.3n + 560p) |
16kHz | 2.2n |
20kHz | 1.4nF (1n + 390p) |
