3.1Connecting options for the ACX450
Fig. 3.1: Cabling options of the ACX450
The above cabling is suitable for sessions in the rehearsal room or for practicing at home. Connect your guitar to the instrument input jack of channel 1. If desired, connect another instrument or a dynamic microphone to channel 2.
Connect the supplied FS112 foot switch to the foot switch input at the rear panel. With the foot switch, you can switch the effects units of both channels on and off, which is particularly useful during live performances.
To play along with a playback, connect a CD player to the CD input. Of course, a MD player or a computer can be used as playback device as well.

Models ACX900 and ACX1800 offer a wide range of additional connecting options. The above figure shows only one of many possible installations:
The instruments, microphones, the foot switch as well as the CD player are connected as shown in figure 3.1. The tuner is connected to the tuner output where there is a constant instrument signal. If you wish to integrate external effects units, you can do this separately for each of the two channels. Connect the input of the effects unit to the INSERT SEND of one of the respective channels, and connect the effect output at the unit to the INSERT RETURN jack of the same channel. Instead of the two stage effects units shown here connected in series in the signal path, you can establish a parallel effects loop, e.g. by means of a 19" studio effects unit. In this case, connect the input of the effects unit to the MIC INSERT SEND or the INSTRUMENT INSERT SEND output, and feed the stereo output signal of the effects unit through the CD INPUT jacks. You can then use the CD LEVEL controller to mix the effects signal and your guitar signal. With this option, please note that the effects unit only returns the effects signal (100%Wet) and not the original signal.
Musicians who wish to play their instrument through a PA system during a live session normally need a DI box. A DI box prepares the signal for transfer through long cable lines, so that a higher output level for the mixing desk can be achieved. You will be delighted to know that your ULTRACOUSTIC comes with a builtin DI box! Connect the balanced LINE outputs directly to the mixing desk input or to the
