The iAXE624 can either be connected directly via jack to an amplifier or by connecting the provided USB cable to your PC/Mac computer. At the same time, the USB connection acts as power supply for the iAXE624 guitar.

Fig. 2.1: Control elements and connections




You can use a commercially available ¼" TRS for the - connection.

You can connect the guitar with the USB connection to your computer via USB. The blue control LED indicates that a connection to the computer has been established.

The ¼" TS connection can be used to connect the iAXE624 guitar to any standard guitar amplifier. (See Fig. 4.2)

You can use the TONE-controlT1 to reduce the high frequencies from the guitar's neck pickup.

You can use the TONE-controlT2 to reduce the high frequencies from the guitar’s mid pickup.

The VOLUME controller lets you change the volume of the guitar output. The headphone volume needs to be changed by using the software on the computer.

These controllers affect both conventional and USB output.

We would like to draw your attention to the fact that extremely loud sound levels may damage your hearing as well as your headphones/loudspeakers. Turn the VOLUME control fully to the left before you switch on the unit. Be careful to select a suitable volume at all times.

When using your guitar with the supplied GUITAR COMBOS software, please note that the volume setting of the virtual amplifier is saved for each individual preset. This may result in a noticeable difference in volume when changing from one preset to another.

Use the pickup selector switch to select different pickup combinations (see table 2.) Each position has it's own sound.

-To avoid damage to the USB plug or socket, disconnect the USB cable from the guitar when the instrument is not being played. Take extra care not to stand the guitar on the USB plug.

-For more information on tuning and maintenance of your guitar, please read the tutorial which is included with your guitar.

-Visit our homepage for more information about setting up the tremolo, the intonation and the action of the strings on your guitar. We recommend that such adjustments are performed only by an experienced guitar technician.

-When replacing strings on a guitar with a tremolo system we recommend changing strings one-by-one.This ensures that the tremolo system remains in balance during the whole procedure and reduces the risk of string breakage due to overtensioning. Furthermore, it takes much longer to restore the correct positioning of the tremolo and to tune the guitar after restringing if all strings were removed at once.





The iAXE624 USB-Guitaris an extraordinary guitar. You can connect it directly to a computer and record music or play along to your favorite songs. Additionally, you can enjoy the exciting sounds of virtual guitar amps and stomp boxes. The iAXE624USB-Guitaris the perfect solution if you want to start playing immediately. It is soeasy—plugand rock!

4.1 Operation of the USB connector

Fig. 4.1: Wiring of the USB guitar

Use the USB cable, which is included, to connect the iAXE624

USB-Guitarto your computer. The USB unit of the iAXE624 USBGuitar is buspowered—noseparate power supply is needed. The blue LED below the USB connector () lights up and the system will indicate the connection of a USB audio unit.

Connect your headphones to the PHONES-connectoron the guitar, which is located directly above theUSB-connector.If you don’t want to use your headphones, you can also connect a pair of active monitors to thePHONES-connector—theBEHRINGER

MONITOR SPEAKERS MS16 as well as the DIGITAL MONITOR SPEAKERS MS20 and MS40 are a perfect choice for this application. If you own a mixing console, you can do the following: connect a stereo input of the mixing console to the PHONESconnector and the active monitors to the control room outputs of the mixing console.

Instead of using the USB function of the guitar, you can also use the guitar the same way as a conventional electric guitar. To do so, simply connect the ¼" TS connector ( ) to a guitar amp instrument input. This gives you the opportunity to play without a computer, for example, when jamming with your band.

The conventional guitar output works independently from the USB connector, meaning you can simultaneously play via the USB port and a guitar amp. This way, you can set up a means of direct monitoring to avoid latency problems.

The advantage of this setup is that while listening to the sound coming from your guitar amp, you can record a clean guitar sound.

Using plug-ins,you can experiment with different effects and amplifiers afterwards.

4.3 Using the iAXE624 with a BEHRINGER V-AMP

If you're in need of latency-freemonitoring during multitrack recording, then the BEHRINGERV-AMPis the ideal partner for your iAXE624. Make the connections as follows :

-Connect your iAXE624 to the V-AMP'sinstrument input using a standard instrument cable.

-Connect the iAXE624's headphone output to the V-AMP'saux input using a balanced cable with stereo phone jacks.

This allows you to use the V-AMP'saux level control to adjust the playback volume.

To record the guitar, connect your iAXE624 to the computer using the USB cable. You can set up your prefered monitoring sound on the V-AMPand record the dry, unprocessed guitar sound on your computer. For this purpose you should use a sequencing software, for example the program Kristal which can be found on theCD-ROMincluded with the iAXE624 package.

4.2 Connection to a guitar amp

Fig. 4.2: Connection to a guitar amp





With both connection options—thecommon guitar output and the additional USBoutput—avariety of applications are at your disposal. Thewell-known¼" output jack can be connected to the input of your guitar amplifier as usual. With the help of the integrated

USB interface you turn your computer into an ultimate recording studio.

Whether for studio application or practicing at home, the audio connections used always remain the same:

5.1 Wiring

When connecting your CENTARI iAXE624 to a conventional guitar amplifier, we recommend using a well-shielded,low-noiseinstrument cable.

Fig. 5.1: Unbalanced instrument cable with ¼" TS connector

5.2 Headphone connection

The iAXE624 USB-Guitarprovides a connection for headphones. You can connect any standard commercial headphone with a ¼" TRS jack plug. For mini TRS jack plugs, you will need a suitable adapter. You can see the required pin allocation from the following diagram.

5.3 USB cable

The iAXE624 USB-Guitarcomes with a USB output for connecting USB compatible devices like notebooks or MP3 players. Here you can connect any standard USB cable.
