SLAM! Gets it Loud - Up to 80dB Total Gain Available!

The Manley SLAM! stands for "stereo limiter and microphone preamplifier" - and it gets loud fast. Starting with the two tube microphone preamplifiers, the Manley SLAM! gives you 48V phantom power, phase reverse, and up to 60dB of gain and 20dB more gain in the limiter - plenty to accommodate virtually any microphone and singer. On the limiter side, Manley combined the electro-optical circuit from the ELOP with a fast FET-based brick-wall limiter and added a handy sidechain. From clean to crunchy to punchy, you can have it with the Manley SLAM!

Manley SLAM! at a Glance:
  • Dual-channel tube microphone preamplifier
  • Electro-optical and FET-based brick-wall limiter
  • Excellent VU metering
  • Flexible I/O

Dual-channel tube microphone preamplifier
On both channels of the Manley SLAM! you have tube microphone preamplifiers with switchable phantom power and phase reverse. Plus, the new tube circuit features up to 60dB of gain - and there's 20dB more gain available in the limiter, so you've got plenty of juice to handle low output ribbon microphones and soft singers. The input attenuator is on the front and there's also a variable pad. Apart from XLR microphones, you can give your line-level instruments a warm-up using the front-panel DI inputs.

Electro-optical and FET-based brick-wall limiter
The Manley SLAM! boasts two different and distinct limiters - available simultaneously or separately on each channel. Manley's famous electro-optical circuit, found on their ELOP, is onboard - plus it features a convenient sidechain highpass filter. Offering two knobs, the ELOP is easy to use and "just works." There's also a fast FET-based "brick wall" limiter onboard as well that delivers everything from ultra-clean to gravelly - just as you'd expected from an FET limiter. The Release control lets you dial in a host of colors, and a Clip setting allows for an extremely round shape. Use both limiters at the same time to get as much of each effect as you like.

Excellent VU metering
With Manley's SLAM! you can meter raw input levels, the final output levels, and ELOP Limiter gain reduction, so you can keep an eye on what's going on. Plus, there's a switchable pad on the VUs at 0, -3dB and -6dB so you can keep the needles from going in the red when you're mastering. In addition, there are fast and accurate multicolor LED ladder peak meters that let you know the input and output levels as well as the FET gain reduction. The LED meters do Peak, Peak Hold timed, and Peak Hold until reset. You can also manually set where the bars change colors, to match up the SLAM! with your other gear.

Flexible I/O
On the back panel of the Manley SLAM! you have plenty of I/O to work with. Transformer-balanced I/O and 1/4" phone jacks are onboard. In addition, four TRS jacks allow you to insert external equalizers into the sidechains. Another input allows linking multiple units for surround purposes.

The Real Thing!!!

The Manley SLAM is one of our most used tools. It is the Swiss Army Knife of our studio. When running our SF-12 stereo ribbon with the limiter wide open there is plenty of gain to capture the quietest string instruments on one day and with a SM7B and BOTH the electro-optical and FET brick-wall limiters grabbing a screaming rock vocal the next. We also use it for synths and drum machines to make them sound HUGE and sit right in the mix. It also works great with almost all program material on a stereo mix together with the Manley Vari Mu. For me there are no plug-ins that can capture the sound of great rack gear. We all use our favorite plug-ins and yes they come close and do sound great but there is nothing like finishing off your mix with the real thing. I can’t say enough about Manley products!!! They stand by their gear with a 5 year warranty. Now that’s something in this day and age.

Sweetwater Advice

Kenny Bergle

Believe it or not, the SLAM is an unbeatable value at this kind of price point. Not only do you get two of the best sounding Class-A, tube preamps available, but you also get BOTH electro-optical and FET brick-wall limiting on both channels. Nothing has been compromised in this package that WILL give you THE sound you have been looking for.

John Bamber

The Manley SLAM! is an absolute must-have for any professional studio or mastering house. It exemplifies versatility in design, and limitless in possibilities. I had it connected to my Digi002 and, using Pro Tools, was able to run different sources through it and I really was fascinated by its sound. The mic pre's were stunningly clear and had a warmth like an evening campfire. I recorded acoustic guitars and vocals, both of which came out very clear and warm. When I used a combination of the limiters on a female vocal, it sat in a mix like no vocal I've ever processed; it was like sonic velvet. On a stereo mix the limiting was smooth, but after turning up the input to drive the tubes it put some grit on the mix that was certainly nice for that particular style of music. All in all, the SLAM is a terrific item that could easily find it's way into your studio and broaden your aural horizons for years to come.
