General
The 90W ACX900 has two channels: one with a single 6.3mm input jack and a second with a 6.3mm input and XLR input, making it the ideal simplifier for a one-man show with an acoustic guitar and a mic for vocals. You can easily adjust the gain to determine the volume for each channel.
On the rear panel you'll find a stereo RCA input for connecting an external audio device, such as an MP3 or CD player. If you're just getting started with the guitar, this is a great way to play along with your favourite music. On the other hand, if you've been playing for a longer time, you can use the CD input to play music during breaks in your show. Two XLR line outputs send a signal directly to a mixing board, and you can connect an external effects processor with the 6.3mm instrument insert send and return jacks.
Both channels have a 7-band EQ, equipped with Behringer's FBQ feedback detection system for immediate feedback elimination. You also get a 24-bit effects processor with sixteen fantastic presets, such as reverb and delay, per channel. A foot switch comes with the delivery as well, so you can easily control the effects.
The instrument channel (on the left side) consists of a phase switch that determines the phase - a function that can eliminate the feedback that's common in acoustic guitar pickups. Both channels also have a tuner switch that mutes the speaker so you can tune your guitar with an external tuning device. This can be directly connected to the amplifier via the Tuner Out 6.3mm jack on the rear panel. Furthermore, two original 8-inch dual-cone speakers project your sound with the utmost precision.
