Digiamps PWM amplifiers and Switch-Mode Power Supplies are based on many years experience with audio design and power conversion design.

One of our preferred amplifier designs is precision clock based with half-bridge or full-bridge output section and overall feedback after the output filter , this gives a design which has very good audio qualities and very good thd specs, it is unconditionally stable and frequency response is only slightly dependant on load impedance.

For multi-channel applications we think it is the best configuration too.
Lately more integrated designs have matured, we have made designs with these too
and we focus on these for low and medium power designs to keep the cost down.

EMC and noise issues are dealt with from the design phase and we use multi-layer pcbs with ground planes and decoupling combined with EMC filters at the output and power inputs.

Our switch-mode power supplies (SMPS) are designed to power audio amplifiers with the very fluctuating load this presents to the supply and they are again unconditionally stable and works very well into no load or full load.

Power factor corrention (PFC) becomes very attractive or mandatory at high power levels, the PFC circuit ensures a load from the AC line very much like a true resistive load and unlike the very high peak currents associated with normal power supplies (SMPS or linear).

Typical applications for our amplifers (and power supplies) are;

*HIFI amplifiers

*Home Cinema Amplifiers

*Active Loudspeakers

*PA amplifiers

*ELA amplifiers

*Musical Instrument Amplifiers

*Industrial Amplifiers

*CAR audio amplifiers
