[. . . ] Avoid spraying insecticides near the unit. . · Maintenance: Your new amplifier is rugged. It was built to give you a lifetime of trouble-free operation, if it is operated in accordance with the instructions contained in this manual. The only maintenance required is cleaning. If you are going to move your amplifier around frequently, we recommend a road case to protect it from scratches and road wear. . . · · · Moving the Unit: Before moving the unit, be certain to disconnect any interconnection cords with other components, and make sure that you disconnect the unit from the AC outlet. 9 700RB Series 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Front Panel Controls 19 Front Panel Controls 1-Balanced Direct Out: 9-High Mid: An electronically balanced output, that you can run to your P. A. system. 2-Pre/Post EQ Button: Boost and cut at 1 kHz +10dB, "Q Optimized, " band pass type. Works on lower string harmonics, and effects the punch of your sound. 10-Low Mid: Selects the direct out signal from before or after the EQ. 3-Direct Level Out Controls the level at the direct out jack. 4-Input: A standard ¼" input jack and input attenuator button. The button is generally left out, except in rare cases when the clip LED flashes. 5-Tuning Mute Button: Boost and cut at 250Hz +10dB, "Q Optimized, " band pass type. Works on the main body of your sound. 11-Bass: Boost and cut at 60Hz +10dB, shelving type. Controls low end push. 12-Boost: Set this switch to "On" when tuning up. No signal will be sent to the speakers, or the P. A. system. 6-Volume: A post EQ gain stage using GIVE technology which adds "growl" as it is turned up. 13-Tweeter/Master: Sets pre-amp gain after the input stage. It is used in conjunction with the input pad, to optimize the amplifier's headroom. 7-Voicing Filters: String Bass: Controls output level to tweeter. 14-Tweeter Hi-Cut: Cuts frequencies above 10kHz, producing a more "cone" like sound from the tweeter. 15-Woofer/Master: Setting this button voices the pre-amp for basses with "B" tuning. Leave it out and the amp is voiced like the 800RB, for 4 string basses. Contour: Controls output level of 380W amplifier. For BiAmp operation, this controls the woofer level. 16-Woofer X-Over: Drops the mid-range frequencies while boosting lows & highs. Presence: Set this button to engage the electronic crossover for the woofer. The tweeter is always crossed over. 17-Effects Loop: Adds edge and definition to higher frequencies. Active Equalization: 8-Treble: Boost and cut at 7 kHz +15dB shelving type. Add or remove edge and definition. Send and return jacks provided for the insertion of effects after the EQ, but before the boost section. Some effect units have gain, turning the BOOST down, will compensate for this. 18-Tuner Output Output to tuner. 19-Power Switch Turns the amplifier on or off. Should a problem occur during operation press this switch first. 10 700RB Series 3 Rear Panel Controls 1 2 Rear Panel Controls 1- AC Receptacle: The power cord is detachable and plugs in here. 2- 380W Amp Only: CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE 380W AMP AND THE 50W AMP BE CONNECTED TOGETHER OR BE CONNECTED TO THE SAME SPEAKER !!! 380W power amp output for Full-Range operation only. Higher impedances such as 8 Ohms, 16 Ohms, or No Load are acceptable. No damage will result from operating the amplifier with the speakers disconnected. 3- Speakon Outputs: Enables BI-AMP operation by connecting a GK-RBH Series cabinet with the provided 4 conductor Speakon cable. This connects the 50W amplifier allowing the Tweeter control on the front panel to control the signal going to the horn. [. . . ] technology produces a consistently pleasing bass tone. 14 700RB Series Tech Talk Cool Running = Reliability: The 700RB Series uses a "dual rail power supply" that generates about half the heat of conventional amplifiers. Low output signals run off a low voltage supply, and high level signals run off a high voltage supply. This keeps the amp running a lot cooler and makes it much more reliable. To cool the amp when its being driven hard, we've designed a temperature sensitive fan cooling system. [. . . ]
