User manual ROLLS LA120

[. . . ] The compressor keeps things nice and level--it boosts the quiet things and attenuates (lowers the gain) the louder signals. The LA120 usess an automatic ratio mode where it follows the mix and sets the attack and release rates for you. This means that it starts compressing a signal that goes over the threshold at a gradual, smooth rate. [. . . ] If obvious physical damage is noticed, contact the carrier immediately to make a damage claim. We suggest saving the shipping carton and packing materials for safely transporting the unit in the future. Please complete the Warranty Registration Card and return it to the factory.

Connect the Output of the LA120 to an equalizer or another piece of signal processing equipment, then to an amplifier or recording device. The tip being the "send" and the ring being the "return". If this is the case with your mixer, use an insert cable, like the one shown below, and connect the "tip" cable to the LA120 Input, and the "ring" cable to the LA120 Output. ACTIVE -O O 0 - 20 +20 LEVEL THRESHOLD COMP/LIM GAIN REDUCTION ACTIVE Switch: Engages and disengages the compression. THRESHOLD: Sets the level at which the income signal must overcome in order for the LA120 to begin compressing. COMP/LIM Switch: Switches the LA120 from Compression mode, to Limiting mode (explained in the Operation section of this manual). NOTE: When switched in, the LA120 is in Compression mode;when switched out, the LA120 is in Limiting mode. VU Meter: Indicates the amount of gain reduction. Connects to tip Connects to ring REAR PANEL DESCRIPTION MADE IN THE U. S. A. SERIAL NUMBER For recording, the LA120 should be connected in a channel's insert. If this is not possible, try to get the LA120 connected between the microphone (or instrument) preamp, and the mixing board channel. Do not plug a microphone directly into the LA120 because it is not a preamplifier. If you are using the LA120 with an instrument, place it after your preamp and before your effects. SAMPLE SETTINGS Note: The examples given are starting suggestions only. For light compression such as vocals or program compression, set the THRESHOLD control at approximately 1 O'clock and press the COMP/ LIM switch in for compression. For more applications requiring more compression such as instruments, decrease the THRESHOLD to 10 to 12 O'clock.
