In practice, I set the Out Ceiling to 0.1. This sort of confidence means that when mixing, you can be sure that no digital clips will occur on your digital master. The above-threshold signals are limited, while all below-threshold signals undergo a constant gain change that is controlled by the difference between the Threshold and Out Ceiling settings.The Out Ceiling level can be considered the absolute maximum level coming out of the unit, no matter what happens on the input of the L2. It follows exactly that when you adjust the threshold 10 dB below the highest input level reading, you see about 10 dB of gain reduction indicated on the Attenuation meter. The first time I used the L2, I was conservative, but I soon discovered I could use large values such as -12 dB and push the output level up 12 dB. If the Threshold is set to 0 dB, the output exactly reflects the input (within 0.1 dB), but as you lower the threshold value, the output level actually goes up. I found this feature handy when using the unit as two separate mono limiters: It saved the lower channel's setting, which I used on a bass synth.Setting the Threshold control is different from an analog limiter. When unlinked, the bottom knobs return to their previous values. When two channels are linked for stereo, the top knobs slave the lower knobs. The values of these continuous rotary controller knobs are displayed on six bright LED alphanumeric displays that are visible across any control room. A rear panel RS-422 port could be used for future software/firmware updates or for recalling stored front panel settings from a computer database.L2 AS LIMITERAfter the inputs (analog or digital) are set, there are three main controls to adjust: Threshold, Output Ceiling and Release.

Sync selections include internal (via a low-jitter clock), digital-which strips sync from S/PDIF or AES/EBU data streams-or slaving to an external word clock. These range from 0 to -96 dB and have an automatic peak hold function that's resettable from the front panel.D/A conversion is handled by an AKM AK4324 chip, and the unit can operate at 88.2 and 96kHz double sample rate modes. Separate left/right +/-10dB input level trim controls let users tweak analog input operating levels, and six 16-segment LED meters display input level, output level and attenuation (gain reduction) for the left and right channels. The rest of the analog "front end" was co-designed by Hutch of Manley Labs and Evegeny Klukin at Waves. The L2 outputs audio as simultaneous analog and digital signals, making it ideal for mixing to both analog master tape recorders and digital media at the same time.The A/D converters are AKM AK5393 chips with two Burr-Brown INA103 chips per channel for balanced input and output amplifiers. Digital I/O includes both AES/EBU XLRs and S/PDIF RCA jacks. Its IDR (Increased Digital Resolution) function is a requantization process that increases the perceived digital resolution by as much as three bits or 18 dB.Analog audio enters and leaves the unit as either balanced signals via the XLR connectors or as unbalanced through 1/4-inch jacks. Like the L1 process, the L2 increases the average audio level and maintains absolute maximum peak levels without clip and without adverse side effects.

No other accessories included.Here is some info / specs from Mix magazine:Designed to be the last process in the mixing chain or in the mastering studio, the L2 is a stand-alone, 48-bit/96kHz two-rackspace hardware unit, based on Waves' second-generation technology from its L1 Ultramaximizer mastering software plug-in.

the switches are still there and can easily be pressed with a pen or similar object.Auction is for Waves L2 with AC power cable only, as pictured.
