QUAD COMPRESSOR / LIMITER

Quick Start

Rejected Rane advertising slogan #1743: “C4. It’ll blow your mind!”

We’re not entirely sure why the marketing department didn’t like the idea, but be assured: unlike its explosive material namesake,

the C4 Quad Compressor will not blow up. Heck, it won’t even spark or sizzle under normal circumstances. e only thing smokin’

will be your mix, thanks to the C4’s smooth compression, precise dynamic EQ and ultra-fast limiting.

Each of the C4’s four channels oers a full-featured compressor with selectable Compressor and Dynamic EQ modes. In ad-

dition, an oversampled, brick wall LIMITER is included for catching signal peaks. COMP, THRESHOLD, RATIO, ATTACK,

RELEASE and KNEE give full control over the audio envelope. e compressor is toggled on and o using the ACTIV E/BYPASS

switch; the Limiter is engaged at all times and is not aected by this switch. Limiter operation is completely independent of the com-

pressor with its own LIMIT THRESHOLD control and Headroom meter. Channels 1 & 2, and 3 & 4 can be LINKed to maintain

a proper left/right stereo image, with channels 1 and 3 acting as the MASTERs, respectively.

For the ultimate in dynamics processing exibility, the C4 includes both internal and external side-chain functions, with a full

PEQ (parametric EQ) section included for good measure. External side-chain mode is automatically selected whenever a connector is

plugged into the rear panel SIDE-CHAIN jack. Selecting LISTEN mode routes the side-chain audio to the channel output, allow-

ing you to hear the eect of PEQ adjustments when doing frequency-sensitive compression or de-essing. If you'd prefer to not use the

side-chain PEQ, simply set the PEQ GAIN to 0 dB.

Setting up the C4 is a breeze thanks to the fast, accurate side-chain and Gain Reduction combination meter. For users unfamiliar

with de-essing, the  pointer on each control indicates a recommended setting for this specialized application. e Auto attack and

release mode speeds up sound check, and the Tips and Tricks on page Manual-8 serve as a handy reference guide for getting started

with compression. ank you for taking the time to read this Quick Start. We now return you to your regularly scheduled sound

check or recording session.
