From their beginning, MANLEY LABS have been closely involved with numerous mastering facilities around the world. For these most demanding engineers in our industry, they have created specialised products such as our all-tube tape repro head amps, digital converters, high-powered vacuum tube monitor amplifiers, through to custom monitoring consoles, all the way up to complete facility design and installation. 

SLAM! stands for "Stereo Limiter And Micpre" and it pretty much describes what it will do to most VU meters. Manley had to put a switch on this limiter to drop its internal VU meters down 3 & 6dB to keep the poor little needles from bending– it'll get LOUD fast (hence the exclamation mark).

The Mastering Version of the SLAM! incorporates detented and logable 1/2dB steps built with 1% metal film resistors on sealed gold-contact Grayhill switches is in full production. 

Key features:

• No mic preamps or instrument inputs. Instead the tube sections are paralleled for lower noise & distortion
• All pots are replaced with rotary switches for detented resettability & easier calibration
• True hard-wire bypass function, which is not possible on the regular version with mic preamps, etc
• Dedicated unbalanced transformerless inputs
• ELOP limiter has 5 ratios, which may put it into the compressor/limiter category
• FET limiter has 5 modes
