[. . . ] If the clip LED flashes excessively, push the button marked -10db in. Occasional clip light flashes while playing very hard is okay. 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. When adjusting it, do it a little at a time. 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. [. . . ] The Backline 350/210 has an extremely high current capacity, over fifty amps, so it doesn't need current limiting circuits for overload protection. There is nothing in the Backline 350/210 power amps to come between you and your sound except faithful, raw power. Contour: Contour is used to completely revoice the amplifier. The Contour control tunes between two different shaping circuits, with greatly different response. With the control all the way up, the low end is slightly boosted, the mids are dropped and the high end is pushed up. [. . . ]
