[. . . ] This emphasizes brushing sounds, allowing you to strum with a more edgy feeling. (MIC/LINE CHANNEL) Connect mics and line-level devices here. This handles balanced input, so you can connect 1/4" phone TRS jacks and XLR-type connectors. fig. 030 4. 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. XLR TRS · Use the following sequence when connecting mics that require phantom power: 1. Refer to "Example of Using Two Channels Combined" (P. 13). 3. · Supplying phantom power to mics that do not require it or supplying it to other devices may cause such equipment to malfunction. * 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. 2. PICKUP button This switches the input circuitry for either piezo or magnetic pickups, according to the type of pickup on the connected guitar. * Set this to MAGNETIC if your guitar has an active pickup equipped with a preamp. 7 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. 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. The AC-60's phantom power is output at a constant 48 V, so it conforms to professional specifications required at recording studios. 9. 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. 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. 10. 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.
