INSTALLATION STEP 1

COHERENT STEREO™ /

MIXED-MONO / BRIDGED MONO

The REFERENCE Class A amplifiers have the ability to operate in any one of the following modes:

Coherent Stereo™ with identical left and right stereo channels for maximum fidelity. Best choice for satellite speakers. Use this mode unless Mixed-Mono is necessary.

Mixed-Monoin order to drive stereo and mono simultaneously; works well for center channels. It can be used anytime you need a summed mono channel. Somewhat sacrifices sonic accuracy as additional circuitry is introduced to one channel. In Mixed-Mono, the left channel is inverted, see diagram below or on the bottom of the amplifier.

Bridged Mono for dedicated single channel operation; ideal for driving subwoofers. It is also used when large amounts of power are necessary for single speakers. In bridged mono, only the right channel input is active.

In bridged mono, only the right channel input is active.

NOTE: If you intend to drive a REFERENCE Class A amplifier in Mono but have stereo outputs from your crossover or source unit, you can put the switch in

BALANCED / UNBALANCED INPUT

The REFERENCE Class A amplifiers have the ability to accept either a standard Unbalanced RCA signal inputs, or a Balanced "Pro Audio" inputs with the use of the Soundstream BLT Balanced Line Transmitter or some other balanced line audio source. Before installing your system, you should decide

The REFERENCE Class A amplifiers' signal inputs accept two ranges of input signal levels: 0.2 - 2.0 Vrms, or 0.5 - 5.0 Vrms for both Balanced and Unbalanced inputs. The input range switch position and level settings are dependent upon the preamplifier / source unit output signal level. For the best system Signal to Noise Ratio, we recommend that the input level controls be set as far down as possible (rotated counter-clockwise), while maintaining an acceptable level of output.

Using the "Unbalanced" RCA input

When using the Unbalanced RCA input, the RIGHT channel input signal switch MUST be in the "UNBAL" position. Also, when first installing the amplifier using this input configuration, we suggest that the left channel input signal switch be in the "UNBAL" position as well. If you experience alternator wine or other installation noise with both switches in the "UNBAL" position, try moving the LEFT channel input signal switch to the "BAL" position. This should remove any system noise due to installation.

Using the "Balanced" RCA input

When using the Balanced 6-pin DIN input, both switches MUST be in the "BAL" position. Also, we recommend that when using this input configuration, the "INPUT LEVEL" switch be in the "0.5 - 5V" position, and the gains on the

Class A 10.0, Class A 5.0 specifications

Soundstream Technologies has established itself as a frontrunner in the field of high-fidelity audio equipment with its innovative Class A amplifiers, most notably the Class A 10.0 and Class A 5.0. These amplifiers exemplify their commitment to superior sound quality and advanced engineering.

The Class A 10.0 amplifier is designed for audiophiles seeking unparalleled audio performance. It boasts a remarkable power output of 100 watts per channel, ensuring that even the most demanding speakers can be driven effortlessly. One of the standout features of the Class A 10.0 is its true Class A operation, meaning it operates at all times in the Class A range, delivering a warm and rich sound signature. This type of operation reduces distortion significantly, allowing for a more authentic reproduction of audio across various frequencies.

In contrast, the Class A 5.0 amplifier caters to smaller setups without compromising on sound fidelity. With an output of 50 watts per channel, it is ideally suited for compact systems or near-field monitoring applications. Despite its smaller size, the Class A 5.0 still utilizes Class A circuitry, promising a similarly lush audio experience.

Both models integrate innovative technologies to enhance performance. They utilize high-quality components, including carefully-selected capacitors and low-noise transistors, which contribute to the amplifiers' exceptional sound clarity. The advanced thermal management system ensures that these amplifiers maintain optimal operating temperatures, enhancing reliability and durability during extended listening sessions.

Additionally, the integrated power supply in both amplifiers is designed to minimize voltage fluctuations, further refining audio output. This feature is crucial for preserving the integrity of the sound, especially during peaks in musical dynamics. Each model also features a fully balanced input, which significantly reduces noise interference from external sources.

In summary, the Soundstream Technologies Class A 10.0 and Class A 5.0 amplifiers are perfect embodiments of the brand's dedication to delivering exceptional audio performance. With their Class A operation, powerful outputs, and advanced technological features, these amplifiers stand out in a competitive market, appealing to audiophiles and casual listeners alike. Whether for a home theater system or a studio setup, these amplifiers guarantee a superior listening experience characterized by clarity, warmth, and minimal distortion.
