Press down the button for magnetic pickups. * Set this to MAGNETIC if your guitar has an active pickup equipped with a preamp. 3. SHAPE button Setting this to ON modifies the midrange to create a bright tone suitable for strumming chords. This emphasizes brushing sounds, allowing you to strum with a more edgy feeling. 4. PHANTOM switch This turns the phantom power on and off. Set this to “ON” when connecting mics that require phantom power (condenser mic, etc.). Set this to “OFF” when connecting mics that do not require phantom power or other devices. • Use the following sequence when connecting mics that require phantom power: 1. Turn the PHANTOM switch off. 2. Connect the mic. 3. Turn the PHANTOM switch on. • Supplying phantom power to mics that do not require it or supplying it to other devices may cause such equipment to malfunction. Always be sure to turn the switch off before connecting. * To protect the circuitry, all output is muted momentarily after the PHANTOM switch is turned on or off. * Phantom power is supplied only to the XLR connectors for the MIC/LINE channel INPUT. * Noise may be produced if connectors are connected or disconnected while the phantom power is turned on. 1 2 3 6 7 8 9 10 11 16 17 4 5 12 13 14 15 18 XLR TRS Names of Things and What They Do Names of Things and What They Do Phantom Power Because they have a comparatively wider range and better sound quality than dynamic mics, condenser mics are often used for miking acoustic guitars. However, they require a power source to operate. Although some condenser mics run off batteries placed within the mic housing, in many cases a type of power supply known as “phantom power” is required. This power supply uses the existing mic cable to feed power. The AC-60’s phantom power is output at a constant 48 V, so it conforms to professional specifications required at recording studios. 5. SELECT button This switches the input level to match that of the connected device (mic or line). You can connect guitars with magnetic pickups when LINE is selected with the SELECT button. * Note that the volume is increased if the switch is set to “MIC” when you have a line-level device connected. 6. VOLUME knob * When using the AC-60 with the GUITAR channel and MIC/ LINE channel mixed, adjust the volume balance between the two channels with the VOLUME knob. (GUITAR CHANNEL) This adjusts the volume of the GUITAR channel. * To accommodate the lower output of piezo pickups, the volume level when the VOLUME knob is between the 7 and 10 positions is set somewhat higher when the PICKUP button is set to PIEZO in comparison with the MAGNETIC setting. (MIC/LINE CHANNEL) This adjusts the volume of the MIC/LINE channel. 7. BASS knob This adjusts the level of the low-frequency range. Turning the knob to the right (clockwise) emphasizes the feeling of body in the sound. 8. MIDDLE knob This adjusts the level of the midrange. Turning the knob to the right creates a fatter sound when melodies or individual notes are played. 9. TREBLE knob This adjusts the level of the high-frequency range. Turning the knob to the right emphasizes brushing sound when chords are stroked. The tone of acoustic instruments varies immensely from one instrument to the next. The kind of sound required also varies according to how an instrument is being used in a particular ensemble. Actively use the BASS, MIDDLE, and TREBLE knobs to adjust the tone to suit the instrument you are using and the conditions in which it is being used. (Example) • When using the AC-60 with the speaker stand attached, you may want to turn up the BASS knob so the lower range is perceived better. • If the sound seems too harsh, such as immediately after changing strings, you may want to turn down the TREBLE knob to cut back on the high frequencies. 10. CHORUS button This turns the chorus on and off. The indicator lights up when this is on. You can use a foot switch (the optional BOSS FS-5U) to switch the chorus on and off. Turning the chorus on and off with the foot switch works on both channels. 11. CHORUS knob You can switch between the three types of chorus (SPACE, RICH, and WIDE) by setting this knob. You can adjust the amount of effect applied by changing the position of the knob. * This is enabled when the CHORUS button is in the ON position. * The markings indicating the SPACE and RICH positions are approximate. Listen to the sound to confirm the effect as you make adjustments. SPACE This is a spacially synthesized chorus. With spacially synthesized chorus, a method available only in stereo, the chorus effect is created by taking the sound from the right speaker, from which the effect sound is output, and the sound from the left speaker, which outputs the direct sound, and then mixing them in the actual space. This creates a greater lateral spread than that produced when the sounds are mixed electronically, providing a more natural sense of breadth.
