Topping PA7 Class D Balanced Amplifier

Topping PA7 Plus utilize a new Class D amplifier circuit with a variety of exclusive optimization techniques, which has powerful low distortion performance and power output. These technologies ensure a clearer, cleaner, deeper sound without any background noise. In addition, the balanced structure is able to reduce noise during transmission, thus enabling better performance of the audio source and avoiding wasted performance.

Impressive output power

Despite their small size, the PA7 Plus is capable to deliver 300W x 2 to a 4-ohm load at 10% distortion. With a 1% distortion standard, the 4-ohm load will output 245W x 2. These power outputs and low distortion levels are sufficient to meet the needs of most speakers and applications.

Multiple input options

The PA7 Plus offer two sets of input connectors: Combo connectors (compatible with XLR and TRS) and RCA connectors, ensuring compatibility with a variety of audio sources.

Volume control

You can control the volume of the PA7 Plus, or set to bypass the volume control of PA7 Plus.

12V trigger input for seamless integration

Both the PA7 and PA7 Plus feature a 12V Trigger input interface, allowing you to connect them with other devices for synchronized on/off switching.

Track Audio at a glance (download brochure)

Our range of speaker stands are built with a devotion to detail that will add modern elegance to any room, available in Satin Black or Silver anodised finish.
Also, gorgeously machined and a huge sonic upgrade, Track Audio has created an entirely new product category for us: speaker spikes. An off-shoot of a British machining company with clients in the military, aerospace, medical and automotive industries, Track Audio creates astonishingly high-quality products from high grade steel. Designed to last a lifetime and sound great doing it.

Good Vibrations?
You would not build a house without strong foundations?
Or drive a car with loose suspension. So why expect your hi-fi system to perform at its best without the proper support?

Your hi-fi works by generating sound waves. However for every action, there's a corresponding reaction: in this case, unwanted vibration and resonance. No matter how good your loudspeakers, the in-room audio quality can be significantly reduced by the effect of floor resonance, producing sonic effects ranging from muddy and indistinct notes to a harsh and wearing sound.

Track Audio precision-made speaker stands, isolation feet, spikes and spike shoes are designed to eliminate these effects and unlock the full potential of your hi-fi system.

Precision, Quality and Control
Track Audio's range of support solutions is the result of detailed analysis into the detrimental effects of floor resonance caused by high-output loudspeaker designs. every product and component is designed and manufactured in-house in the UK from the highest quality materials, using detailed computer modelling and ultra-precision machining to ensure meticulous attention to detail and excellent performance.

We pay equally careful attention to the sourcing of materials and traceability of all parts and processes. All machined parts are produced to ISO 9001 standards.
