The Trak Pak from Empirical Labs combines the Mike-E microphone preamplifier with the Lil Freq equalizer to form a powerful and flexible channel strip for professional audio engineers working in the studio or in a live sound environment. The Mike-E includes a multi-stage soft-clipping saturator circuit, a compression circuit based on the Distressor, a two-stage emphasis circuit that boosts and soft-clips high frequencies before the CompSat circuit, and a Mix knob that provides parallel compression, allowing for a blend of the uncompressed and compressed sounds.

The Lil Freq equalizer offers eight sections of processing including a High Pass section to remove low frequencies, High and Low Shelving to smoothly and musically boost or cut high and low frequencies, four bands (LF, Lo-Mid, Hi-Mid, and HF) of fully parametric EQ, and a dynamic EQ section that works as a de-esser and high frequency limiter. Each section offers a dedicated bypass switch, allowing the engineer to effectively A/B the effects of each section to adjust and fine-tune them.

  • EL-9 Mike-e Microphone Preamp and Compressor/Saturator

    The EL-9 Mike-e from Empirical Labs is a transformer-coupled mic preamp with compressor/saturator circuits that deliver classic knee compression, as well as versatile tonal coloring. This low noise transformer input amplifier section offers precise digital control over gain and has a signal-to-noise ratio of 130 dB. It features stepped control knobs for gain control and a "BAD!" LED indicator for alerting the user when input signal is overloading the circuit.

    The front panel instrument input that allows the unit to function as an ultra-clean Direct Box. The saturator is a multi-stage soft-clipping circuit that provides triode-type saturation effects, while severely flattening out the peaks. The compressor circuit is based on the Distressor, but with a longer attack time. Preset ratios include 2:1, 4:1, 8:1, and Nuke. Emphasis improves the signal to noise ratio, while soft-clipping high frequencies before the CompSat circuit and cutting the frequencies after it.

    Mix provides the parallel compression technique achieved by mixing between the compressed and the dry, uncompressed signal. This can often help maintain transients and a sense of dynamic range while enhancing the low level nuances. A stereo link connector allows two Mike-e processors to be used for stereo buss functions, while the optional send/return insert modification allows for additional processors, such as the Lil Freq EQ, to be connected between the mic preamp and compressor, forming a powerful and flexible channel strip. The Mike-e ships with a standard IEC power cord.

  • Lil Freq Equalizer

    The Lil Freq from Empirical Labs is a mastering quality equalizer with eight processing sections including two shelf equalizers, a high-pass (low-cut) filter, four fully parametric equalizer bands, and a dynamic equalizer section for de-essing and high-frequency limiting. The Lil Freq utilizes traditional and digitally controlled analog circuitry combined in a new topology, which offers a performance that exceeds most digital EQs in terms of distortion and noise.

    The high-pass section offer eight preset frequencies covering 30 to 330 Hz to remove low frequency content, while the high and low shelving sections offer musically smooth boost and cut on high and low frequencies. The fully parametric EQ section covers 4 overlapping frequency ranges (LF, Lo-Mid, Hi-Mid, and HF) with complete control over frequency selection, cut or boost, and bandwidth. The DS or dynamic EQ section combines tunable filters with a compressor-like circuit that can help control excessive high frequency content, such as sibilants or other sharp transients. The circuit also functions as a soft-knee high-frequency limiter.

    There are both XLR and 1/4" / 6.35mm line-level inputs, each being DC coupled. The XLR output includes a Class-A transformer, which offers isolation from ground loops and hum with soft saturation and a beefy low end often associated with vintage gear. Additionally, there is a 1/4" / 6.35mm instrument input on the front panel, which effectively turns the Lil Freq into an instrument DI for studio recording and live performance applications. The Lil Freq is hand-wired in the USA and ships with a standard IEC power cord.

    • Eight sections of processing
    • Two shelving equalizers, special 3rd order HP (Low Cut) section with 8 selectable frequencies, 4 fully parametric bands, and one dynamic equalizer section

      pretty good banana plugs
      Size: 5 Pack, Pattern Name: Banana Plugs
      i bought these over 6 months ago and i just installed them to the front left and right floor standing speakers - sony ssf-7000 i have them for over 10 years hooked up to a yamaha 7.1 AVR. alot of people have had trouble installing this - one single banana plug comes in 3 parts - the bottom and top (the banana plug tip) can be unscrewed. what i did was tightened the top first (top being the tip of the banana plug) then unscrew the bottom off completely - make sure you have like 3/4" - 1" (depending on your gauge of wire) of exposed speaker wire that is straight - then thread it through the hole at the bottom up - i then rolled the exposed 3/4 - 1" exposed copper wiring into a ball that is bigger than the hole of the banana plug bottom piece so the wire doesn't fall back through where it came from. then i screwed on the top and middle piece back with the bottom piece - tightening it a bit so i know there's good contact. also make sure the tip is screwed in all the way as well as a double check. what you don't want to do is have the copper wire touch the threaded part of the bottom piece - the wire will cut off from the screwing action. i plugged it into my sony speakers and it wasn't a real snug fit - a bit too loose to feel secure - it didn't seem to go all the way in - but it fit fairly well in my receiver. my intention was to use these banana plugs with my 2 channel set up but i decided to go pre-constructed mediabridge 12 AWG speaker cable instead - those fit my 2 channel set up on my receiver and elacs really snug and secure. i tested it and it works fine. i didn't hear any loss of signal or any extraneous noise. none of my (14 awg?) wiring fell through the bottom and it sounds good. so no complaints there. i bought 5 pairs - but i find that it is an odd number to include a package - even numbered pairs would be better. anyway they seem constructed well - easy enough to install and they do work. thanks for reading

      High quality and robust
      Size: 12 Pairs, Pattern Name: Banana Plugs
      Easily the best plugs I've found at a reasonable price. Solid feeling with good quality and they look good with easy to see red/black labeling. The tips tend to unscrew too easily, but this is a non-issue when they are in use, just something you have to be careful not to lose when assembling. It's a bit tricky to spread the wire out evenly at the exact right length. If screwing the plug together is hard at all, go back and shorten how much wire you bend over the lip.

      Solid banana clips
      Size: 5 Pack, Pattern Name: Banana Plugs
      Ah yes, I used these solid banana plugs to convert my wires. It’s pretty easy to set up once the wire housing has been stripped and really cleans things up nicely. I haven’t had any discernable hissing, noise problems, or connection issues.

      Get the right wire guage
      Size: 1 Count (Pack of 1), Pattern Name: Banana Plugs
      I rate the banana plugs themselves 4 stars. They are everything I expected and work as advertised. It's the experience of assembly that I rate three stars. The way these work is -- you strip off the outer insullation of your wire and separate the two leads (positive and negative). Then you strip some length of insulation off the end of one of your leads, you unscrew the banana plug so that it separates into its respective base (lower) and contact (upper) halves, you slip the wire up through the base, you flare the copper strands of the wire and fold the individual strands over the very top of the base (about 1/16 of an inch) (taking care not to extend the strands over the threaded barrel of the base), then you screw the upper contact onto the lower base and voila, banana plug / wire assembly. It's not as complicated as it sounds. Go to the Monoprice website and watch their excellent instructional video. Here's the thing though. While the assembly is not complicated, it is tricky, and if you don't get your proportions right the first or second or third time, you'll have to do it over. Fist of all, if your wire guage is relatively thin, like my 16-guage speaker wire, you'll find that the entire wire, insullation and all, will slip right through the base of the plug without butting up against the bottom of the base. If this is the case, then the wire is left to sort of flop around inside the plug and that has a kind of unfinished, amateur look and feel to it, whereas if the wire butts up against the bottom of the base, it has a solid, one-piece professional look. So, to my mind, there's a sweet-spot for wire guage that works best with this plug -- not too thin and not too thick. And since Monoprice has debunked the thicker-is-better myth (the quality of the copper is the real determinant), then you should feel free to get the wire guage that fits the plug. Next -- and here's where it gets tricky -- once your copper extends beyond the top of the base, you'll need to limit this extension to about a sixteenth (no greatrer than a fourth) of an inch. Then you very delicately flare out the individual strands, in a 360- degree arc, and fold the strands over the top of the base. This takes a fair degree of manual dexterity, especially if the wire is "floating" inside the base and its travel is not stopped where the insullation meets the base. You'll have to hold the wire and base steady in the fingers of one hand, then flare out the wire strands with either your fingers or a suitable object (the working end of a ball-point pen worked for me) with the other hand. This one-sixteenth measure is important. If you extend wire strands beyond the top and over the threads of the base, you'll find that screwing the contact end onto the base is impossible and you'll need to start over. One or two strands is OK and almost unavoidable. In that case the screwing will catch but if you take a pair of pliers to it you can muscle through. By the way, you can avoid the whole mess by getting the open-screw type, which I'm sure will work just as well without any of the hassle of assembly. Like anything else, if you do it a few times to make the mistakes and learn the tricks, then it will become second nature, and if you've already done that, then my review might seem overly fussy. In that case feel free to leave comments to help other readers.

      Wish they came with instructions...
      They are cheap and work great. They plug right into my Pioneer vsx521 receiver and my Paradigm Atom monitor speakers. I wish they came with instructions, because it took me about 10 minutes to realize the bottom part unscrews in addition to the top part. Here are my instructions for installation: 1) Unscrew the bottom part of this connector (the thin metal underneath the red/black ring). 2) Make sure the Banana Plug (which may be loosely screwed into the top part of the connector) is fully tightened down 3) Strip your wire tips to 3/8 of an inch (or just slightly under) 4) Run the first newly stripped wire end through the bottom part you removed in step 1, such that the stripped end of the wire is entering through the flat end and exiting through the smaller threaded end. 5) Leave about 1/8 to 3/16 of an inch of stripped wire hanging past the exit hole. 6) As evenly spaced as possible, bend the over-hanging wire strands over the exit hole (all around it, like a hat). If done properly, the wire should not fall out if you give it a VERY GENTLE tug. 7) Screw the top metal part (with the actual banana plug) back onto the bottom part. It may be difficult if your stripped wire is hanging too low. I've used a pair of pliers to grip the bottom part of the connector while I twist the banana plug side with my hand. If done correctly, you should be able to put a lot of tension between the wire and connector without removing/damaging it. UPDATE: I just recently helped my dad install his 5.1 system without these... it sucked... This item (5 pairs of them in this case) and a good wire stripper can save you alot of pain (both physical and mental). The connectors on the back of his receiver are the kind where bare wire comes in from the side and then the connectors screw down (with a banana plug hole in the center which is where this product would come into play). I felt like a surgeon trying to get a bare wire end into the little slot, and then holding it there while I tighten the connector which is almost impossible since they are so close together... GET THESE!
