Many consumer electronics just don't put enough volume out to drive a high-fidelity amplifier to its peak performance. That's where the PA15 comes in. Add the module into your chain, and adjust the output as needed.

Origin Acoustics® Foundation 2 Channel Preamplifier

Gain staging, or gain structuring is the act of setting the gain for each amplification stage (gain stage) in a sound system to achieve a target system volume that minimizes noise and distortion. Said another way, proper gain staging gives your sound system the best signal-to-noise ratio. By attempting to reach the loudest peaks possible (without clipping) at each stage, you can obtain an ideal gain structure, but to do this, you need to consider each part of your system and understand the principles involved.

Gain staging is the art of setting the volume for each stage of amplification to minimize noise and distortion. While this is a fundamental concept for live sound and recording, it does apply to custom integration as well. Ideal gain staging ensures your sound system achieves the best signal to noise ratio. The goal is to maximize the volume at each point in the chain without clipping. EG: If you have an iPad, a PA15, and an A2150 amplifier, you have three ways to control the gain. One primary way to start this process is to max the volume on your input device, set the amplifier trim at roughly 50%, and then adjust the PA15, up to approximately 80%, until you have achieved the max-loudness your client requires.

If you're still unable to produce enough dB, then adjust the trim on the amp. Just be aware that when you raise the volume on the amplifier or the PA-15, you are increasing the noise floor, which is the amount of signal noise created by all the equipment. So, we recommend only using your pre-amplifiers and amplifiers up to around 80% of their max volume. And while we are proud of the low signal to noise ration of our amplifiers, this best practice will also help prevent clipping when your client maxes the system input out.

Yamaha® 5000 Series Piano Black Preamplifier

In pursuit of the intangible musical quality that breathes life into high-fidelity audio, the world's largest sound company presents the C-5000 preamplifier. From the concert stage to the home, Yamaha has drawn on its vast musical history to create an instrument capable of faithfully reproducing every nuance and emotion in the performance.

Yamaha® 5000 Series Silver Preamplifier

In pursuit of the intangible musical quality that breathes life into high-fidelity audio, the world's largest sound company presents the C-5000 preamplifier. From the concert stage to the home, Yamaha has drawn on its vast musical history to create an ins

Together with the GT-5000 turntable and M-5000 power amplifier, Yamaha delivers an end-to-end balanced signal chain across its flagship models for premier performance.

The C-5000 features fully balanced and discrete circuit transmission across all stages of the signal path at Tone Defeat.

The patented floating design is adopted across the phono EQ, input amp and line amp stages — removing the influence of ground noise from the signal.

The folding-book design for the preamplifier PCB mirrors the left and right signal paths for precise matching and layout.

With each channel physically identical, the C-5000 is capable of the most accurate reproduction of audio, which is both wide and deep.

Further, the ground loop is minimized when other components are connected.

Adopting independent, dual toroidal transformers for the left and right channels delivers optimal separation and therefore produces a sound stage which is faithful to the original source.

Low magnetic leakage lowers adverse impact on the audio signal. Following detailed research based on trial listening, the power transformer was enclosed in a copper-plated case to suppress magnetic flux and vibration. This also assists in minimizing the influence of flux in the phono circuit. This realizes an even and spacious sound due to enhanced reproduction of detailed signals.

By copper-plating the chassis to minimize the influence of voltage on the circuit, the C-5000 is capable of expressing the subtlest nuances as well as powerful bass.

Additionally, thick screw-type wires are utilized to reduce the impedance of the power supply and maximize the transmission of musical information.

The C-5000 was designed from the ground up to deliver the ultimate in listening experiences — down to its aesthetic and even its touch.

The knobs and lever switches feature original designs to communicate both innovation and craftsmanship.

The volume knob is both rigid and precise — employing ball-bearings and precision-cut aluminum to achieve its touch while the lever switches have also been refined for enhanced operation.

Every aspect of the C-5000 was carefully considered when designing this flagship model. Its construction exudes master craftsmanship and reflects an obsession with achieving the highest levels of performance.

The feet are no exception. Like the M-5000, the custom heavy-duty brass feet function either as fully supported spikes or with a scratch guard base for use on delicate surfaces.

Designed from the ground up for custom installation, the “QS” represents the ultimate integrated solution for filling every room in a home with extraordinary sound.

The QS packs four rooms of audio streaming and eight channels of audiophile-grade amplification into a remarkably slim, 1U-high enclosure, allowing you to fully-optimize your valuable rack real estate.

Multiple QS units can be used together to expand up to 32 zones with simultaneous playback of linked groups up to 20 zones each. In addition, the QS offers four zone pre outs that enable it to be combined with the Yamaha XDA-AMP5400RK, a companion multi-room amplifier, to provide more power or more speaker coverage for large areas in a home. The pre outs may also be used to connect powered subwoofers or subwoofer amps.

As a member of the MusicCast family, the QS integrates seamlessly with Yamaha AV receivers, sound bars and more. Now everything – from a surround sound home theater to a bedroom TV system to in-ceiling speakers in the kitchen – can all work beautifully together.

Access all of your favorite music, including built-in streaming services and music libraries on smartphones, tablets and networked-attached storage devices.  (Streaming service availability varies by region.)

Want to hear TV sound or vinyl records throughout the home? Link to a MusicCast receiver, sound bar or turntable to access audio from virtually any source.

The QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart homes.

It's also easy to set up and control with the free MusicCast app, which offers unique personalization features including the ability to assign custom images to rooms, and to rename, rearrange and hide sources.

No ordinary amp, the QS employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification at 50 watts/channel (8 ohms) with an outstanding 10 Hz to 22 kHz (+0/-3 dB) frequency response and 106 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms).

The curse of the custom integrator: ground loop hum, a common and vexing side effect of connecting a bunch of electronics together in a rack. The QS takes care of it with a brilliantly-engineered differential circuit design. Sometimes it’s what you don’t hear that sounds the most amazing.

Experience every detail of your favorite recordings. The QS supports high-res audio playback up to 192 kHz/24-bit, and employs the same premium ESS Sabre DACs (Digital-to-Analog Converters) and PML capacitors used in our flagship AVENTAGE AV receivers.

The audio performance of the QS is further enhanced with a suite of exclusive Yamaha technologies, including our Compressed Music Enhancer, Advanced Bass Extension Processing and volume adaptive EQ. The result – it always sounds great.
