Pulsar Modular R52 Baxandall is a software recreation of the tone-control circuit published by Peter Baxandall in 1952. It models the original feedback-based EQ network with the SP61 pentode, published component values, and the operating conditions described in the original design.
The plug-in uses a single feedback network for both bass and treble controls rather than treating the two frequency ranges as independent bands. Changes to either control affect the behavior of the other, while the SCOPE provides a visual representation of their interaction.
The valve stage is integrated into the EQ feedback loop, making input level part of the processing behavior. R52 also provides controls for source impedance, load behavior, and the treble shelf configuration based on the alternatives described by Baxandall.
Software Overview
Pulsar Modular R52 Baxandall recreates the 1952 Baxandall tone-control topology as a software processor. The EQ network, valve amplifier stage, source impedance, load characteristics, and treble shelf options are presented as adjustable parameters.
Key Features
1952 Baxandall Circuit
Recreates the tone-control circuit published by Peter Baxandall in 1952, including the SP61 pentode and specified component values.
Single Feedback Network
BASS and TREBLE operate as two arms of a single feedback network, allowing changes in one control to influence the response of the other.
Integrated Valve Stage
The SP61 pentode is incorporated into the feedback loop that forms the EQ response rather than being used as a separate saturation stage after the filter.
Input Level Interaction
INPUT controls the amount of valve processing, making signal level an integral part of the resulting EQ behavior.
SCOPE Display
The SCOPE visualizes the interaction between the bass and treble controls as adjustments are made.
Adjustable Circuit Conditions
SOURCE controls the impedance feeding the network, while LOAD adjusts how tightly the amplifier interacts with the 15 Ω monitor.
Treble Shelf Options
SHELF provides a choice between the two treble endings described in Baxandall's published design.
System Requirements
System requirements were not specified in the provided source information.
