Max 115 Schematic Exclusive: Peavey

Peavey MAX 115 is a robust 300-watt bass combo amplifier known for its technical reliability and proprietary tone-shaping features. Its internal design is documented in a detailed Bill of Materials and various service manuals that reveal the sophisticated circuitry behind its "exclusive" sound. Core Circuitry and Schematic Features The schematic for the encompasses several critical stages:

TransTube® Technology: This patented solid-state circuitry emulates the harmonic characteristics of tube amplifiers. In the schematic, this is often represented as a gain boost stage that, when engaged, also automatically bypasses the tweeter to provide a more authentic, gritty "growl".

DDT™ Speaker Protection: A hallmark of Peavey engineering, this compression circuit prevents the power amp from clipping into square waves, protecting the 15-inch speaker from damage while maximizing clean output.

Psycho-Acoustic Low-End Enhancement: This digital signal processing (DSP) element adds subharmonic frequencies to the signal. It creates the perception of deeper bass without physically taxing the speaker or demanding more power from the amp. Key Components & Layout

According to the technical documentation available on sites like Scribd, the MAX 115 board (Assembly #99060580) consists of over 150 components:

Power Stage: Modern versions utilize lightweight Class D topology, though older iterations may vary.

EQ Section: A three-band equalizer with specialized push-button presets: Punch (+6dB at 100Hz), Mid-Shift (adjustable center frequency), and Bright.

Inputs/Outputs: Dual 1/4" inputs for active and passive instruments, plus a balanced XLR Direct Interface (DI) with a dedicated Ground Lift to eliminate hum.

The Peavey MAX 115 schematic reveals a sophisticated solid-state design centered on high-efficiency power delivery and versatile tone shaping. As a 60-watt to 300-watt (depending on the specific generation) bass combo, its internal architecture is built around Peavey's patented TransTube® technology and the speaker protection system. Equipboard Preamp and Tone Shaping peavey max 115 schematic exclusive

The input stage of the MAX 115 is designed to handle a wide range of signal levels through attenuated active and passive inputs. TransTube® Circuitry:

This stage utilizes proprietary solid-state components to emulate the harmonic distortion and dynamic response of a tube amplifier. The "TT Boost" switch increases gain to produce a characteristic "growl" without significantly altering the overall output volume. Equalization (EQ):

The schematic incorporates a semi-parametric EQ section. This typically includes a three-band setup (Bass, Middle, Treble) with a dedicated

switch to adjust the center frequency of the middle control, allowing for precise tonal sculpting. Voicing Options:

Many MAX 115 models feature exclusive voicings such as "MAX," "Vintage," and "Modern," which modify the internal EQ curve and gain structure to suit different playing styles. Equipboard Power Amplification and Protection

The power section of the MAX 115 is engineered for reliability under heavy load. DDT™ Speaker Protection: A critical component of the schematic is the Distortion Detection Technique (DDT)

compression circuit. It monitors the power amp's output and automatically reduces gain if clipping is detected, protecting the 15-inch heavy-duty woofer from "square wave" damage. Class D Topology: Newer 300-watt versions of the MAX 115 utilize lightweight

power amp modules. This allows for high power output with minimal heat generation, which is often managed by a dedicated power supply PCB. Psycho-Acoustics:

The circuitry may include a "Psycho-Acoustics" button that adds subharmonic frequencies, creating a perception of deeper bass than the cabinet might physically produce otherwise. Full Compass Systems Connectivity and Maintenance Peavey MAX 115 is a robust 300-watt bass

The schematic layout provides several professional-grade routing options. Direct Out (DI): An XLR balanced output includes a Ground Lift

switch to eliminate hum caused by ground loops when connecting to mixing consoles. Auxiliary and Effects:

The board includes a post-EQ effects loop and specialized inputs for headphones and media players (CD/Aux) for practice sessions. Serviceability:

Abstract

This document analyzes the schematic architecture of the Peavey Max 115 bass amplifier. The unit is historically known for utilizing Peavey’s "_transtube" solid-state technology or modern Class D topology depending on the revision year. This paper dissects the three main stages found in the schematic: The Pre-Amplifier (Op-Amp based), The Power Amplifier (MOSFET/Transistor output), and The Power Supply (Switching vs. Linear). Special attention is paid to Peavey’s proprietary feedback loops and protection circuits.
