Pulsar 1178

The most versatile FET compressor

A compressor that eats transients for breakfast, the 1178 is a rare and expensive legend of the recording studio, cleaner and more versatile than its older brother, the 1176. The 1178 has been used by great producers including Chris Lord-Alge (My Chemical Romance), Bob Clearmountain (Rolling Stones, Christina Aguilera), Yvan Bing (Phil Collins) and Nigel Godrich (Radiohead).

The Pulsar Audio 1178 software meticulously recreates the original 1178 hardware in its tonal colour and compression character.

But Pulsar Audio have taken the 1178 further than the original unit, adding all the features you would expect from a modern, versatile plug-in, including a full sidechain EQ for added control, an optional saturation stage for warmth and character, and precise metering.

Improving on a classic

Pulsar 1178 has a fast and bright character, making it great for dealing with unruly transients in tracking and mixing. While these qualities make it the ideal choice to smash the transients of a drum room to get a nasty rocky bounce, the extended attack range also allows gentle dynamic contouring and can provide unique mid-band definition and intelligibility on a vocal.

When it comes to compression, having more control over the sidechain signal can bring a mix to the next level. The dynamics of a drum groove hinge on how compression is triggered by both the kick drum and the snare. With Pulsar 1178’s full-featured sidechain EQ section, you can make each one hit just the right amount of gain reduction.

Keeping an eye on dynamics is key to a well-balanced mix. Pulsar 1178’s accurate and modern metering section helps in this important task. Peak meters allow insight into overall dynamics; RMS meters let you monitor loudness and match levels, and a scrolling view helps visualize how the attack and release settings are affecting the gain reduction.

Add grit and drive to the usually-transparent 1178 with four flavours of saturation: Tape, Triode, Warm and Clip modes open up new ways of managing dynamics and spectral envelope. These modes are fully-integrated in the compressor’s gain reduction system, allowing a unique vibe, unachievable with pre or post saturation.

How does it sound?

• Snappy with a rich sound: More transparent than an 1176, the 1178 allows incredibly fast control over transients when compared to other compressor models. Add the all-buttons-in mode and Pulsar’s added saturation models, and you can access characterful, colourful tones as well
• Vocals: The 1178 is a great way to get vocals to pop out of a mix and sound very aggressive. Bob Clearmountain has used these circuits to do the business on vocals from Mick Jagger, Christina Aguilera and more
• Drum overheads: The 1178 has the speed to catch crashes in a flash, and also opens up the top end of a signal in a very natural-sounding way. Chris Lord-Alge uses this combination to great effect on “lacklustre overheads”. With lookahead, you can get surgical with your drum transients too
• Bass: Whether you’re catching transients, controlling dynamics, or all-out smashing up the signal, bass is prime fodder for the 1178. Using the added Saturation circuits, you can really introduce extra grit, helping the bass to pop through a mix and survive on smaller speakers
• Acoustic guitar: Guitar transients can be particularly fast and harsh, and the 1178 is a great tool to dampen lively picking, as well as to make the body of the sound bounce and respond. Fast processing and natural release helps to add life to a mix but retain a natural guitar tone
• Buss and master compression: Transparency and speed make the 1178 a good candidate for buss compression and even mastering compression (as on Robert Plant’s album Angel Dance). The added sidechain EQ is helpful in controlling the entire frequency spectrum – not just heavy bass
