Description
Jeff Rowland Model 535 Power Amplifier
From a single Jeff Rowland Model 535 Power Amplifier in stereo mode at the core of an intimate audio system, up to multiple bridged units powering a complex home theater setup, down to a bridged pair driving a sophisticated two-channel environment, the Model 535 delivers exquisite resolution, authority, and control to speakers of almost any size and any load.

Features
Machined Aluminum Chassis
Precision-machined chassis, milled from a solid block of aircraft grade aluminum, provides exceptional thermal heat transfer/dissipation, RFI/ EMI shielding, resonance control, and minimizes micro-phonically induced microvibrations from any source.
Ceramic Circuit Boards
Critical audio circuits are implemented on mil-spec, multilayer, low dielectric constant, Rogers™ ultra-rigid ceramic circuit board substrate for extremely low energy retention and absorption. Large low impedance ground planes areas for extended internal star-grounding.
Balanced Topology
Inherent cancellation effects of balanced topology implemented throughout power and input/output circuits ensure reduced distortion and noise under dynamic signal conditions.
High-Precision Surface Mount Components
Extensive use of Lead (Pb)-free, low temperature coefficient, active and passive surface-mount components results in significantly smaller loop areas, reduced circuit capacitance and inductance, and introduces less noise than conventional leaded components.
Thin-Film Resistors
All resistors are low noise, 0.1% thin-film type for extremely low thermal noise which complement the low-noise characteristics of the active circuitry.
Teflon Insulated Wires
All signal carrying input and output wires are teflon insulated, for low dielectric energy storage, ensuring that each audio note naturally decays into the deeper silence of the music.
Transformer-Coupling and Isolation
Transformer coupled input circuitry provides universal component compatibility and virtually eliminates ground loop noise and RFI/ EMI. Transformer coupling ensures identical amplifier overall gain when using unbalanced input adapters.
Active Power Factor Correction
Power Factor Correction (PFC) integrated into the power supply reduces AC line harmonic noise pollution and increases AC line power utilization to 97%.
High-Efficiency Switch-Mode Power Supply
Highly efficient, compact, light weight, switch-mode power supply provides optimum voltage regulation for all circuits and operating conditions, and allows for quiet operation over a wide range of AC mains power sources.
Binding Posts
CE approved speaker output terminals require no tools for secure, low resistance connections.
Front Panel Standby Button
Illuminated front panel push-button switches the amplifier into standby mode (<0.3 watt consumption). An internal switch allows the user to dim the front panel indicator light “ring” or shut off the light altogether when the amplifier is powered on. REMOTE ON/OFF: A 1/8” (3.5mm) mini plug connector on rear panel permits amplifier power on/standby switching in remote and home theater applications. ><0.3 watt consumption).

Remote On/Off
An 1/8” (3.5mm) mini plug connector on rear panel permits amplifier power on/standby switching in remote and home theater applications.
