This compact design blends a simple, intuitive and versatile high voltage, 3 tube, 6 stage classic style analog preamp with an internationally proven high performance Class D power amplifier. This Class D amplifier and SMPS module is enhanced with our PATENTED P.H.A.T. (Proprietary Heat Abatement Technology) topology. This delivers robust and reliable, high output performance in a tremendously compact and convenient package. The result is a versatile bass amp that exudes fat, rich tones while remaining very articulate. The All Tube Class A preamp operates at over 300 volts and can be used to add a little warmth to your tone or dialed up a little to provide a wide range of natural tube overdrive. Our simple “streamlined” objective was to build an amp that allows the player to focus more on their playing style and less on adjusting the knobs on their amplifier. So, whether you’re a straight ahead 4 string player or an extended range expressionist, your voice will come through. The Streamliner™ 900 features a rugged chassis with solid extruded aluminum panels and a faceplate that is CNC machined from solid billet aluminum. The entire chassis is then brushed and anodized in a Tungsten finish. The chassis is designed for roadworthy durability, superior fit and finish. Simply put, this 900 watt bass amplifier offers a more streamlined approach to finding your voice, yet still carries forth the GENZ BENZ reputation for performance, reliability and innovation. FRONT PANEL INPUT – The Streamliner™ 900 is equipped with a .” unbalanced instrument input directly feeding a conventional tube voltage amplifier stage. The input sensitivity range is from 15 mV to 1.6 volts with an input impedance of ~1M ohms. INPUT SIGNAL MUTE SWITCH – With this Mute switch, you can place the amplifier (and the Direct Output) in mute mode without having to change any of your amp settings. This feature can also be used for silent tuning since the Tuner Out stays active when the mute is engaged. A red indicator LED above the switch indicates when the Mute function is active. GAIN SWITCH – This switch sets the gain sensitivity of the preamp gain stages. With the switch set to the IN position and the Amber indicator LED illuminated, the gain stages are set to a higher sensitivity, driving the preamp gain stages harder, producing more harmonic content and overdrive. The degree of overdrive will depend upon the output level of your bass guitar pick-ups and preamp as well as your playing style. This switch should be used in conjunction with the Gain control for setting the overall gain structure of the preamp. This switch can also be used as an Active/Passive switch. The lower gain position is more suitable for high output level active basses and a cleaner tone. GAIN CONTROL – This control sets the input gain of the 12AX7 TUBE preamp. The volume of the signal is then controlled by the Tube Preamp Volume control and also the Master Volume control. Note that overdriving the input tube gain stage may be a desirable tonal characteristic of your playing style. This control, in conjunction with the Gain switch, Preamp and Master Volume controls, allows you to set the amount of tube overdrive or clean tone your amp produces. PREAMP VOLUME CONTROL – This control sets the volume (and make-up gain) of the preamp after the Input and EQ stages but before the Effects Send jack. Use this control in conjunction with the Gain and Master Volume controls to achieve the necessary gain structure for your playing and music style. SETTING YOUR INPUT SIGNAL – Use the following guidelines to set your amplifier input stage for the type of bass used and your personal playing style. These guidelines are just a suggested starting point. 1) Set your instruments controls (volume and tone) where you normally prefer to run them. 2) Now set all controls on the Streamliner™ to 12 o’clock and the Gain switch “out”. It may be best to start with the Master Volume at 9 o’clock. 3) For a clean tone, your Tube Gain and Preamp Volume settings may be set to similar positions. For a clean tone using a hot Active bass your Tube Gain setting should be set more towards the 9 o’clock position and the Preamp Volume at noon to 2 o’clock positions. 4) For overdriven tube tones with Active or Passive basses your Tube Gain setting will be set higher and the Preamp Volume set lower. If you are looking for an even more overdriven sound, engage the Gain switch for even more preamp gain. Set your Master Volume for your desired overall volume. We suggest experimenting with different settings for best results. 5) Now, turn your attention to the EQ section and make the adjustments for your desired tone. Because this is a semi-active EQ network, any larger settings of cut or boost will affect the gain level of the preamp which will allow for even more variability in overdriven tones. 6) After setting your EQ it may be necessary to go back and adjust your gain and volume levels level up or down accordingly....
