2. Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. 1.) Passive Bass Input - this is a 1/4-inch, 2-conductor input jack for plugging in your instrument. It is intended for bass guitars, but will accept other instruments as well. 2.) Active Bass Input - this is a 1/4-inch, 2-conductor input jack for instruments with active electronics or high output. 3.) Tube Gain - adjust this control clockwise to increase the amount of gain. Set this control in its lower ranges to achieve the cleanest tones. As this control is turned clockwise, you’ll begin to hear the grit and growl of a classic overdriven tube amp. At maximum settings, thicker, more aggressive tones are produced. Note: Gain is applied to the tube stage before the tone controls. 4.) Bass - this passive EQ adjusts the low frequency equalization of the amplifier. 5.) Mid - this passive EQ adjusts the mid-range frequency equalization of the amplifier. 6.) Treble - this passive EQ adjusts the high frequency equalization of the amplifier. 7.) Master- this controls the overall volume level of the amplifier. Note: Your DE50 features an exclusive Kustom® circuit called Organic Clipping™. When the Master volume level is turned up to its higher ranges, this power amp circuit reacts like an all-tube amp, generating lower order, musical harmonics and natural clipping characteristics like the best all-tube designs. It provides the classic power amp “growl” that bass players know and love, with a smooth transition from clean to grind. 8.) Jewel Light - when lit, this jewel light lets you know that the amplifier is on. 9.) Power - this switch turns the AC power to the amplifier On and Off. 1.) External Speaker - this is a 2-conductor, 1/4-inch speaker output jack. Rating is 8 Ohms minimum. For full power, use an 8-Ohm speaker load. Higher impedance loads will result in lower power levels to the speaker. The signal path to the internal speaker is disconnected when using this jack. 2.) Headphones - this is a 3-conductor, 1/8-inch, stereo jack. The amplifier’s internal speaker is disconnected when this jack is used. 3.) AUX In - this is a 3-conductor, 1/8-inch, stereo jack that allows playback from a Compact Disc, MP3 player, or other audio device. The volume is controlled by the device that is plugged into this jack. 4.) Balanced Line Out - this XLR jack is used to connect the amplifier to a mixer or other line level amplifier. The output for this jack is pre EQ, so only the gain setting will be reflected on this output. 1.) AC Power Cord Receptacle - AC power cord can be removed for easy storage and replacement if damaged. Insert the AC cord (provided) firmly into the AC receptacle. NOTE: Replace the AC power cord if protective jacket is damaged or ground pin is damaged or removed. 2.) Fuse - The fuse is located in a fuse tray just below the receptacle. Replace only with same type and size. For your convenience, a spare fuse is located inside the fuse tray toward the front. To replace fuse, remove AC power cord. Remove fuse tray by pulling the tab located above the fuse symbol away from the receptacle.
