- Page 4 Thank you for purchasing the Little Labs LL2A™ compressor limiter. First of all, in case you are wondering, the LL2A has absolutely nothing to do with the classic Universal Audio Teletronix LA-2A Leveling Amplifier. The name is similar to grab your attention. The LL2A is a 100% original design.
- Page 5 LL2A is if you select the link button and do not have a link cable in place, it slows way down, creating a slow attack more suitable for bass.
- Page 6 Link button and jack When you have two LL2As, use a TS cable (tip sleeve, short guitar cable) and stick in each LL2A’ s link jack. The output will be controlled independently. The threshold will affect both, and whichever compressors threshold is set higher will be the domi- nant master.

You can split the signal and use a high pass filter on the signal feeding the side chain insert so the compressor won’t react to the kick, only the higher frequency snare.
- Page 8 The Inputs, the Outputs, and the unique LL2A circuit topology The I/O circuit topology of the LL2A is unique. Most audio devic- es have transformers or active circuits to convert a balanced signal to single-ended signals where they then are internally processed then converted back to balanced on the output using more trans- formers or an active circuit.
- Page 9 The LL2A output For the output of the LL2A to have a title of its own, it must be unique, and it is. What is used on the output is part of what inspired me to create the LL2A. The Monotor headphone amp has been an enormous suc- cess for Little Labs, utilizing top-notch passive components and a single very low output impedance simple current driver.
