Product Description

Jeff Rowland Model 525 stereo power amplifier is capable of driving 250 watts into 8 ohms which can be increased to 950W when switched to bridged mode. It is housed in a machined aluminium chassis and features standby button on the front panel and a Rogers ultra-rigid circuitry for lower dielectric absorption and energy retention.

Machined Aluminium Chassis

Aircraft grade aluminium is used for the chassis of the 525 power amplifier. It has been precision-machined with integrated heat-sinks which provide excellent thermal heat transfer/dissipation, exceptional RFI/EMI shielding, and resonance control.

Transformer Coupling Isolation

Specially designed input transformers,with Cardas copper wire provide universal component compatibility whilst ridding the system of all ground loop noise, RFI and EMI. Transformer coupling ensures identical amplifier overall gain when using unbalanced input adaptors.

High- Efficiency Switch-Mode Power Supply

The Model 525 features a high-efficiency switch-mode power supply which is lightweight, and can power up to 900 watts of switch-mode power supply at 8 ohms when in bridged mode. It provides optimum and regulated the voltage for all circuits and operating conditions, providing an extremely quiet operation over a broad range of AC mains power sources.

High Precision Surface Mount Components

Pb free lead and active/passive surface-mount components which are low temperature coefficient are used extensively in the 525 stereo amplifier resulting in smaller loop areas, decreased circuit capacitance/inductance, and less noise than typical leaded components.
