User manual GALLIEN-KRUEGER BL210

[. . . ] For our part, we at Gallien-Krueger are pleased that you chose us, and are determined that you will be a satisfied customer. In choosing a Backline 350/ 210 product, you now own an amplifier with many unique features, which will allow you to create your own distinct sound. To get the most out of your new purchase please take a few minutes to read through this manual. If you are in a hurry, we suggest you at least read through the Quick Start and Safety Information sections before setting up your new rig. [. . . ] The Voicing Filter should be turned all the way down (or switched off) to get a flat response. Set the A/B switch to off (Channel A). 4. Using an instrument cable, connect your bass to the Input jack and turn the power switch on, set the master control to 3 o'clock, slowly bring the Level-A volume up and play. Do not turn the volume control in the input section past 1 o'clock unless you want an overdrive effect. If you have a bass with passive electronics make sure the controls are all the way up. If you have a bass with active electronics, turn all of the EQ controls on the bass to the middle or flat position. . . 6 Backline 350 & 210 Settings and Sounds The Backline 350/210 is versatile in its sound and tone. Below are a few suggested amp settings that can be used as starting points to define your own sound. Note: the Gain/Overdrive settings will vary according to the output of your bass. * Contour note: Settings & Sounds At higher playing levels the contour should be set lower for mid-range clarity. To get the 800RB contour voicing, the contour should be set to 0 or 10 only. Tube Style Grunge: Both pickups recommended. Insane Gain: Back pickup recommended. Deep Bass: Front pickup recommended. Slap: Both pickups recommended. 7 Backline 350 & 210 Sound Tips The Backline Series has several unique features which, if used properly, will obtain that sound you have been searching for. Sound Tips The Equalizer: The Equalizer is used to fine tune your sound. These are active circuits, and small changes can make a big difference in your sound. With a little experimentation you will find that this equalizer is very easy to use, never sounds weird and provides you with a large variety of great sounds, unique to GK. Direct Out: The Backline 350/210 provides a low noise, high quality balanced direct out for connection to PA and recording consoles. With the Pre/Post EQ switch set to "Pre" (Out), the direct output signal is fed directly from our low noise, high headroom, FET input stage providing a low noise output superior to external direct boxes and impedance transformers. The Direct Output signal is only effected by the -10dB Pad, and Tuning Mute controls. This allows you to adjust your tone and volume on stage without changing the Direct Out signal level and confusing your sound man. Changing the Pre/Post EQ switch to "Post" (In), sends the "GK sound" and preamp response to the Direct Out jack. This gives you complete control over the Direct Out's tone and volume. In addition, a Ground (Gnd) Lift switch is included to remove hum and buzz when connecting to equipment powered by a different ground system. Contour: Increasing the Contour level will scoop out mid-range frequencies while boosting the highs and lows. The sound, once again, is unique to GK and unavailable on any other Bass amp. Lower contour settings are recommended for midrange clarity at higher playing levels. For 800RB voicing, set the contour control either on 0 or 10 (Off, On on 800RB). Overdrive: The Overdrive channel allows you to create entirely new bass sounds. It is used in conjunction with the input pad, to optimize the amplifier's headroom. 6-Contour: Drops the mid-range frequencies while boosting lows & highs. Active Equalization: 7-Treble: Turns the amplifier on or off. This turns the amp off, but does not completely disconnect the power from the AC mains. [. . . ] Be sure that you are not exceeding the maximum recommend load described in this manual. If the problem persists, contact GK directly for technical advice. Equalization: Standard tone controls and graphic equalizers give you plenty of variation, but they don't provide what the instrument really needs. The equalization in Gallien-Krueger amplifiers reflects 30 years of continuous development and refinement. The GK equalizer is unique to the industry, it's not just a normal four band equalizer, each section is a special circuit optimized to perform a Bass specific job in its range of operation. [. . . ]
