POWER AMPLIFIER – The Streamliner™ 600 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™ 600 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™ 600 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.
CHASSIS DESIGN – The Streamliner™ 600 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™ 600 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.
