        Benefits of Jeff Rowland Model 735 Mono Block Power Amplifier: 

        Machined Aluminum Chassis
        Machined Aluminum Chassis

        Precision-machined chassis with integrated heat-sinks, milled from a solid block of aircraft grade aluminum, provides exceptional thermal heat transfer/dissipation, RFI/EMI shielding, and resonance control.

        Ceramic Circuit Boards
        Ceramic Circuit Boards

        All audio circuits are implemented on mil-spec, multi-layer, 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 all power and input/output circuits ensures greatly reduced distortion and noise under dynamic signal conditions.

        Composite Circuit Architecture

        Unique composite circuit architecture incorporating separate Class AB voltage and current gain blocks with an innovative error correction loop, delivering a sensuous grain-free musicality of unparalleled transparency and low level resolution.

        High-Current Copper Bus-Bars

        High-current, dual polarity, ultra low impedance copper bus-bars distribute both power supply input current and signal output current, virtually eliminating intra-circuit EMI signal contamination, greatly reducing internal wiring, while increasing circuit board rigidity.

        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.

        Transformer-Coupling and Isolation

        Transformer coupled input circuitry provides universal component compatibility and virtually eliminate ground loop noise and RFI/EMI. Transformer coupling ensures identical amplifier overall gain when using unbalanced input adapters.

        High-Efficiency Switch-Mode Power Supply

        Highly efficient, compact, light weight, 1500 watt DC 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.

        Power Factor Correction

        Power Factor Correction (PFC) in the power supply reduces AC line harmonic noise pollution and increases AC line power utilization to 99%.

        Parallel Binding Posts

        CE approved speaker output terminals require no tools for secure, low resistance connections, and allow for easy bi-wiring applications.

        Flexible 20 Amp AC Power

        20 amp AC power inlet accepts a wide variety of after-market high-performance power cables.

        Front Panel Standby Button

        Illuminated front panel push-button switches the amplifier into standby mode (<0.3 watt consumption). 12V 3.5mm jack on rear panel permits amplifier power on/standby switching in remote and home theater applications.

        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.

        Improved Amplifier Isolation

        Proprietary damping material on the bottom of the amplifier chassis completely isolates the amplifier from its supporting structure.
