The design topology of all Soundstream amplifiers utilize multiple Darlington output devices with a total rated output capability that far exceeds the potential output of the amplifier. The D200 II utilizes 1000 watts of dis- crete Darlington output devices while the DlOO II util- izes 500, the Class A 100 1000, the Class A 5011 500 and the D60 II uses 300 watts worth of discrete Dar- lingtons. With such reserves and no current limiting, these amplifiers operate without strain even at maxi- mum output. Power, ground, and speaker connectors are rated to handle up 80 Amps and up to 10 gauge wire.

Unlike most car audio amplifiers, (some of which re- quire a fan for cooling) which shut off when they over- heat, all Soundstream amplifiers eliminate this prob- lem in two ways. First, the Soundstream “Chassisink” has been custom designed to guarantee the lowest possible thermal resistance (maximum cooling) , greatly reducing the possibility of overheating. Secondly, if this should occur, all Soundstream amplifiers incorporate our “Smart Power Supply” which simply reduces the supply’s potential, allowing the amplifer to run much cooler. The entire process is automatic and inaudible. In the case of an actual amplifier malfunction, secon- dary thermostats or fuses will shut down the amplifier in a conventional manner. To prevent potentially damaging turn-on and turn-off thumps, a pair of relays at the outputs allow the amplifier to fully stabilize be- fore sending the audio signal to the loudspeakers, except on the D-60 which utilizes a built in delay circuit .

An especially useful feature in the 0200 II and CLASS A100 is the Linear Subwoofer Extension Circuit (LSE), which compensates for the natural rolloff of most speak- ers and extends bass as much as one full octave.

LSE,provides a linear boost of 6 dB/octave, starting at a point which is continuously variable over the range 35280 Hz. A subsonic filter attenuates the signal be- low 20 Hz.

Only premium parts are used in Soundstream amplif- ers, such as metal film resistors, Glass epoxy circuit boards with corrosion resistant masking, gold-plated input connectors, and immersible sealed potentiome- ters. The heat sink of all models doubles as the chas- sis Each heat sink is custom designed and manufac- tured to Soundstreams exacting specifications facili- tating maximum cooling. Input sensitivity is adjustable to match any tuner/deck, these amplifiers can even be interfaced directly with OEM speaker level signals.

INSTALLATION

Proper installation and adjustment will reward you with reliable operation and optimum performance. Automo- tive sound system installations can be tricky, especially for first timers For this reason, you may want to con- sider using a professional installer who has the tools and more importantly, the experience to do the right job. If you decide to install your equipment yourself, we hope that this manual will serve as a helpful guide.

TOOLS

The only tool needed to make wire terminations at the amplifier will be an insulated flat blade screwdriver. Do not use a noninsulated screwdriver since this may short out against the heat sinks and may damage the ampli- fier .

SELECTING OPERATING MODE

These amplifiers may be configured into two opera- tional modes, stereo or mono. The amplifier comes shipped from the factory ready for stereo usage. If your application calls for the amplifier to be bridged, follow the procedure below:

1.Remove the plug located on the bottom of the amplifier marked STEREO/MONO. Set the switch as indicated on the bottom cover.

2.To complete connection of the amplifier in mono mode, read the input and output connection sections care- fully .

OPTIMIZING FOR SPEAKER IMPEDANCE

D20011,CLASS AlOO, DlOOll, AND CLASS A5011

As delivered from the factory, your amplifier has been optimized for 4 ohm operation. It is possible to opti- mize these amplifiers to deliver maximum performance into 2 or 4 ohms stereo and 4 or 8 ohms bridged. This is accomplished by selecting the correct operating mode on the bottom of the amplifier prior to mounting. Re- move the plug on the amplifier marked for impedance optimization. Set the switch as indicated on the bot- tom cover in the appropriate position for your applica- tion. If you are unsure of the impedance of your speak- ers, or you are wiring more than one speaker to a set of terminals, consult your dealer or installer for the best settings.

DlOO II, D60 II, D200 II specifications

Soundstream Technologies has consistently set a benchmark in the automotive audio industry, and their latest offerings, the D200 II, D60 II, and D100 II, further exemplify their commitment to quality and innovation. These amplifiers are engineered to enhance in-car audio experiences, featuring advanced technologies and robust specifications designed for audiophiles and casual listeners alike.

The D200 II is a powerhouse amplifier, capable of delivering 200 watts of RMS power, making it suitable for driving high-performance speakers with ease. It employs a Class D topology, which not only ensures high efficiency but also minimizes heat generation, allowing for a compact design without compromising on performance. One of its standout features is the built-in low-pass filter, allowing users to customize their bass response according to their preferences. Additionally, the D200 II includes a variable gain control, enabling precise adjustment for seamless integration into any audio system.

The D60 II, on the other hand, is designed for those who seek a perfect balance between power and size. With an RMS output of 60 watts, it is ideal for mid-range speakers or as a companion amplifier for subwoofers in smaller setups. It incorporates sophisticated frequency management technology, allowing users to optimize audio output across various frequency ranges. The amplifier’s compact footprint makes it suitable for installation in tight spaces without sacrificing sound quality.

Meanwhile, the D100 II brings versatility to the table, offering an RMS output of 100 watts. It features Soundstream’s proprietary EQ technology, which enhances user experience by allowing for comprehensive sound tuning. This amplifier is particularly noted for its dynamic range capabilities, ensuring that even the most nuanced audio signals are reproduced with clarity. Users can take advantage of its selectable high-pass and low-pass crossover options, making it a versatile choice for diverse audio setups.

All three amplifiers feature robust build quality, ensuring durability and reliability over continuous use. With sleek, modern designs, they are not only performance-focused but also aesthetically pleasing, making them a fitting addition to any car’s interior. Whether you’re a hardcore audiophile or someone looking to elevate their listening experience, Soundstream's D200 II, D60 II, and D100 II provide a compelling combination of power, technology, and sound quality that is hard to beat in today’s competitive market.
