The 4-band EQ offers HPF, LMF, HMF, and HF. The LMF/HMF sections typically feature switched Q, allowing for narrow or wide adjustments.
Every channel on the 501 Langley is designed for intuitive flow. At the top of the strip, you’ll find the and the 48V Phantom Power toggle.
The Complete Guide to the Amek 501 Langley Mixing Console: Operation, Maintenance, and Legacy
Unlike Neve or SSL, Amek (under the Langley name) did not mass-print manuals for public distribution. They were proprietary documents shipped only to the original purchasers—usually state-run broadcasters. Amek 501 Langley Manual
The electrolytic capacitors inside the PSU should be tested or replaced every 10–15 years to prevent 50/60 Hz hum from entering the audio path. Channel Strip Servicing
Route the signal to the master bus and adjust the master calibration trimpots until the main output registers exactly +4dBu on an external voltmeter. 5. Maintenance and Troubleshooting Guide
, 8-10 auxiliary sends (switchable pre/post), a stereo buss, and a matrix output system. The 4-band EQ offers HPF, LMF, HMF, and HF
The manual typically covers its deep routing capabilities and the innovative SuperTrue automation system GearSource Core Specifications & Architecture Configurations : Commonly found in 40 or 56-channel frame sizes. Channel Strips
The EQ is one of the most celebrated features of the 501 Langley.
In many enthusiast circles, the "Langley" version is far more desirable. Consequently, the manual for the Langley-equipped version is distinct from the standard 501. It contains critical pin-out diagrams and specifications for those proprietary transformer stages, as well as calibration instructions for the Langley EQ sections.

The Amek 501 Langley console was engineered to provide high-headroom, low-noise audio mixing for commercial recording, broadcast, and post-production environments. Graham Langley’s design philosophy focused on minimizing phase distortion, maximizing bandwidth, and ensuring that the equalizer section behaved predictably and musically. Signal Flow and Channel Strip Topology
Smooth high-frequency boost/cut fixed at 10kHz or 12kHz for adding air and clarity.
This is the section repair technicians drool over. The includes multi-page schematics for the Motherboard, Channel Cards, Master Section (including the stereo bus), Power Supply, and even the optional patchbay. Without these, replacing a faulty capacitor or a dead op-amp is virtually impossible.
