These days, going "unplugged" still involves plugging into something. Make the sweet sounds of your acoustic guitar and voice big enough to cut through the clink of coffee cups and casual chit-chat with the ULTRACOUSTIC ACX900.
The Ins and Outs
The 90-Watt ACX900 features two channels: one with a single 1/ 4" input jack and a second with a 1/4" input and XLR input, making it the ideal amp for a one-person show with an acoustic guitar and a mic for vocals. Just turn the GAIN dial to determine the levels of each channel.
On the back panel, you will find a stereo RCA input for plugging in a CD player. If you're just getting started as a guitarist, this is a great way to play along with your favorite tunes. Or, if you're playing an extended set, you can use the CD IN section to provide music during breaks. Two XLR LINE OUT jacks send a signal directly to a mixing board, and you can connect an external effects processor via the 1/4" INST INS SEND and RETURN jacks.
Switch It Up
The ACX900 gives you myriad audio solutions at the touch of a button. Both channels feature a 7-band EQ equipped with BEHRINGER's FBQ Feedback Detection System for instant feedback elimination. You also get a 24-bit FX processor per channel featuring 16 incredibly presets such as reverb and delay. We also include a footswitch for remote activation of the effects.
The instrument channel (on the left) features a PHASE switch that reverses the phase, a function that can eliminate the feedback common in acoustic guitar pickups. Both channels feature a TUNER switch that silences the speaker so you can tune your guitar via an external tuning device, which can be connected directly to the amp via the TUNER OUT 1/4" jack on the back panel.
