FOOT SW Jacks The AC-90 accepts the BOSS FS-5L (latch type), BOSS FS-5U (momentary type), and BOSS FS-6 foot switch pedals. * Set the polarity switch as shown below. fig.071 (MUTE, ANTI-FEEDBACK) Connecting a foot switch pedal (optional BOSS FS-5L, FS-5U, or FS-6) using a connection cable (the optional PCS-31) makes it possible to use a latch-type foot switch (the FS-5L or FS-6) to switch muting on and off, or to use a momentary-type foot switch (the FS-5U or FS-6) to control the anti-feedback feature. * For information on the settings for the FS-6, refer to the owner’s manual for the FS-6. fig.050 When a 1/4” phone (mono) plug is used to connect only one foot switch, only the Mute on/off function is enabled.

You cannot switch the muting off by pressing the foot switch when the MUTE button is on (when the MUTE indicator is lit). * When using an FS-5U (momentary type) to switch muting on and off, the muting is switched on only while the switch is held down. For anti-feedback, a foot switch will function as follows: • When the FREQUENCY knob is positioned in the range from L to H, the switch turns the anti-feedback function on and off. • When the FREQUENCY knob is positioned at AUTO, the switch functions as the START switch for the automatic detection. Holding the foot switch down for one second or longer returns the automatic detection function to standby mode. (CHORUS, DELAY/REVERB) Using a special connection cable (the optional PCS-31) to connect two foot switches (the optional BOSS FS-5U), you can use one FS-5U to switch the chorus on and off, and use the other FS-5U to switch the delay or reverb on and off. fig.060 When a 1/4” phone (mono) plug is used to connect only one foot switch, only the chorus on/off function is enabled. * The chorus on/off function works on both channels. * You cannot switch the chorus on and off by pressing the foot switch when the CHORUS button is off.
