EXCEL CA

About the EXCEL Series

Introducing the entry stereo amplifier from Audio Wave called the Excel.

The Excel has taken two years to complete from design to production. the goal was to create a smaller amplifier but with the same character as the Aspire and Aspire Pro.

This amplifier is built by hand one at a time in the UK and goes through the same process as all the other models , including the testing process.

With all Audio Wave amplifiers, sound and build quality is very important to us. It was a challenge to create such a small amplifier that could produce the power without compromising the sound.

The Excel has a different layout to the Aspire range with the PSU being in the middle of the two channels. The amplifier has only got separate gain controls and a pass through switch on each channel. With the pass through switch you can use the amplifier for bridging or daisy chaining several amplifiers together, this makes installation easier with less cables to run.

The Excel operates in class A/B and can deliver up to 300 Watts RMS into 4 Ohm @ 14.4V in a bridged configuration.

Overall this amplifier is small but can deliver some serious power and each channel is stable at 2 Ohm loads. With the pass through function you can also run a semi active/passive set up with individual gain levels per channel.

The Excel chassis is the same height as the Aspire range so installation combining the two will become a neater installation.

About the EXCEL CA

This amplifier was designed from a request from two very good friends in Italy, Ivan and Francesco who persuaded me to build the Excel CA. They both wanted a class A version of the Excel! I’m so happy I did as this amplifier is such a joy to listen to!

The design is high biased class A/B providing very low distortion and good signal to noise ratio of not less than -97dB. The PCB’s are high quality two ounce double layer and gold plated. All the Sanken output devices are imported from Japan and the SMD resistors in most cases are 1% metal film type. The op amps are Burr Brown and Nichicon Gold Tune and Audio Wave capacitors are used in the preamp and power supply. The power supply uses our double stacked toroidal cores as with all our amplifiers, ultra-high speed half bridge diodes and 75 Amp rated mosfets that ensures trouble free operation.

Every component has been carefully selected to ensure reliability and listening pleasure.

One of the first things you notice about the amplifier is that there are no crossovers, filters or phase controls – only two gain controls. The amplifier has no bridging capabilities unless connected through a DSP.

The Excel Has been designed to drive speaker loads of 2 - 8Ω and will deliver a maximum of 60 Watts RMS into 2Ω @ 14.4 volts per channel and is always running in Class A into 8Ω loads, please have a look at the specification page.

The amplifier has soft turn on and off to stop the speakers from popping as well as voltage rail DC tracking to ensure the main switch mode power supply is always providing the correct voltages.

A large heatsink has been used to dissipate the heat and the chassis has cut outs at the rear for ventilation as the amplifier draws +- 7 Amps at idle.

Don’t let the power output fool you as these amplifiers have won many competitions all over the world!
