The Twin Pak - EL-9 Mike-e from Empirical Labs combines two EL-9 Mike-e transformer-coupled mic preamps with compressor/saturator circuits to deliver stereo classic knee compression, as well as versatile tonal coloring. Each Mike-e provides a 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 a 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 Twin Pak ships with a 1/4" to 1/4" cable for stereo operation and a standard IEC power cord.
