POWER AMPLIFIER – The Streamliner™ 900 uses a state of the art, Class D power amplifier design and a high frequency switch-mode power supply (SMPS) to achieve unprecedented high performance and lightweight packaging. Switch-mode power supplies convert the AC line directly to high voltage DC, then the precision PWM (pulse width modulation) inverter creates a new AC power signal at a frequency more than 1000 times higher than the original wall frequency of 50/60Hz. This new high voltage, high frequency power signal is then fed into a custom high frequency transformer that steps the voltage down, a high frequency rectifier and high ESR filter capacitors finish the process off by converting the high frequency AC signal back to the DC voltages that the amplifier’s internal circuitry uses. One advantage of this conversion process is that the DC power supply rails are refreshed more than 1000 times more often than in traditional linear supplies, thus reducing annoying hum in the audio signal. The high frequency switching is used to reduce the size and weight of the magnetic and filter components while increasing the performance by recharging the power supply rails more often. The Class D amplifier uses digital PWM techniques similar to those in more familiar digital to analog converters to reduce the size and weight by a factor of 10 times that of a comparably rated conventional Class AB amplifier. Essentially, a Class D amplifier converts the analog signal into a logic level PWM digital signal with a digital to analog converter, level shifts this PWM signal up to a higher voltage and current and then reconstructs the analog signal by passing it through what is essentially a power digital to analog converter. Additionally, we developed our own, proprietary 3DPM™ 3-Dimensional Power Management signal processing techniques to give a distinctly analog feel and sound to the Class D platform. This system provides exceptional performance and dynamics retention even for low frequency applications such as bass guitar.

SPEAKER OUTPUTS – The Streamliner™ 900 provides two Neutrik Speak-On™ connectors (wired 1+/1-). The speaker jacks are paralleled. The minimum speaker load is 4 ohms. Do not ground either the “+” or the “-” outputs. Because this is a high voltage, high current output, ¼” output jacks are not provided in order to comply with international safety standards. It is never an issue for the Streamliner™ to be used without a speaker load connected.

POWER INPUT – VOLTAGE SELECTOR SWITCH - The Streamliner™ 900 utilizes a rear panel switch selectable universal power supply that operates from 100V to 240 volts, 50 to 60 Hz for world-wide use. Simply set the switch to the appropriate AC mains voltage (BEFORE connecting to the power source), and utilize the proper IEC cord-set appropriate for the country the product is being used. No fuse change is necessary.

For countries using 100V, 110V, 115V and 120V AC mains, select the 115V switch position on the Voltage Selector switch.

For countries using 220V, 230V, and 240V AC mains, select the 230V switch position on the Voltage Selector switch. There is no externally accessible AC mains (line) fuse, the internal fuse is integral to the SMPS power supply and is not user serviceable. This fuse will not fail except under very unlikely fault conditions to the SMPS, and if this occurs a qualified service technician is required to correct the problem.

ACCESSORIES:

CHASSIS DESIGN – The Streamliner™ 900 utilizes the highest quality aircraft grade, computer machined aluminum chassis. To clean the amplifier, nothing more than a damp cloth and a little bit of glass cleaner (like Windex™) should be used.

RACK MOUNTING – The Streamliner™ 900 is designed to be rack mounted in a standard EIA style 19” equipment rack or tour-case by using the optional rack mounting kit which is available from your dealer.

GIG-BAG – A custom padded carry bag with shoulder strap is available as an optional accessory from your dealer. This padded bag is ideal for convenient carrying of the amplifier. Do not operate the amplifier inside the carry bag, as

the chassis aluminum construction and cooling fan inlet vents are part of the amplifier’s cooling mechanism.

900 specifications

The Genz-Benz 900 is a distinguished bass amplifier that has made a significant mark in the music industry, particularly among professional bassists and venues requiring top-notch audio performance. Renowned for its powerful output and innovative technologies, the Genz-Benz 900 has become a preferred choice for many musicians seeking reliability and exceptional sound quality.
