Performance Manual: Hookup

The following items are included with the Chroma:

The Chroma is designed to operate on either 120V AC or 240V AC (50-60Hz). Check the serial number plate on the rear of the instrument for its power setting. If the voltage setting is incorrect, your local service center can easily change it using an internal switch. Be sure the LOCK/UNLOCK switch (located on the rear of the instrument) is in the LOCK position before power the Chroma to prevent accidental loss of programs. Connect the power cord to the power jack on the rear of the Chroma, and plug the power cord into a grounded three-prong outlet. To reduce the chance of grounding problems, use the same power circuit as your amplifier.

Connect your amplifier to either the XLR-type MONO OUTPUT connector (one of the STUDIO OUTPUTS), or the qaurter-inch MONO OUT jack (either HIGH LEVEL or LOW LEVEL, whichever works best for your amplifier). The Dual Footswitch Assembly should be plugged into the DUAL FOOTSWITCH jack. Connect and using the other pedals will be discussed later in this manual [see Performance Controls: PEDAL Inputs].

When the Chroma's power switch is first turned on, the LEDs (Light Emitting Diodes) will all blink rapidly. During this time, the Chroma is going through its initialization and tuning program. When the circuits are tuned and tested, the PROGRAM NUMBER display will light up with a program number. (If the small DATA READOUT shows "Err" followed by numbers, it means an error has been detected. See the Diagnostics section for more details.)

First center the MONO OUT EQ sliders and raise the VOLUME slider. Then check that the LED over the Program Select Switch ([PROG SELECT]) is lit. Depress [PROG SELECT] if it is not lit.

The Chroma is now ready to play. By pressing any of the fifty numbered switches on the right control panel, you can play the program stored at that location. All 50 of the programs stored in the Chroma's memory can be played in this manner. A listing of the programs is included with this manual.

The Chroma generates and uses radio frequency energy. If it is not set up and used according to this owner's manual, it may cause interference to radio and TV reception.

The Chroma has been tested and complies with the limits for a Class A computing device in accordance with the specifications outlined in Sub-part J of Part 15 of the FCC Rules and Regulations. These rules are designed to provide reasonable protection against interference in a commercial, non-residential area. There is, however, no guarantee that interference will not occur in a particular installation.

To determine whether the Chroma is causing interference, turn it off and observe any change in the interference pattern. If the Chroma is causing the interference, move the TV or radio antenna until the interference stops.
