The Eflex Q5 is a four channel system amplifier housed in a 2U lightweight steel chassis that utilises class D amplifier technology to deliver 1250 w per output channel while weighing just 9 kg. The amplifier package also includes full onboard 96 kHz DSP real time monitoring and can be software controlled via network or USB connection. The package offers a level of flexibility that enables Inspired Audio to offer the Eflex Q5 as the only amplifier option for integrated power and management control of single loudspeakers or systems. Internally the channels are grouped in two channel modules which have an independent mains switch and power supply; as a consequence channel pairs can be easily bridged. This function enables the amplifier to be configured as a four channel, three channel, or two channel unit dependent on the loudspeaker system requirements. Each channel pair also shares a common two in, two out DSP allowing flexibility on programming and product preset selection.

The Eflex Q5 benefits from the power density that can be achieved from modern class D switching topology but also combines this with true audiophile performance. A ground up rethink of the topology which has included the use of modern state of the art semiconductors, a short signal path and turning the inherently low level of negative feedback common with switching designs from a disadvantage to an advantage has ensured that sonic issues common on older class D designs have been eradicated. The result is a fast and open sound that is truly sonically transparent. An holistic approach to design has matched the units switch mode power supplies in harmony with the output stages. Potential sources of noise and distortion have been eliminated and a further benefit is the unit’s ability to auto-select the mains voltage for global operation.
