Louder Than Liftoff CHROMA VS MPQ568C Comparison Page


This page compares the main features and highlights the difference between both units. This page should be treated as the guide for the website visitors and the FAQ section.

The LTL Chroma is the colour format preamplifier capable of holding a single colour module. It has the dedicated mic input and the line/mix input for processing the signals from DAW. The EQ section has a simple LF +3dB and HF +4dB switch boost option. The LF section has two frequncies selection with PCB jumpers: 30Hz and 60Hz. The Input and output are transformer coupled. The Chroma webpage does not provide the performance specification, such as the THD and Noise levels. The LTL Chroma is all-in-one unit with abundance of features: audio transformers, discrete opamps, colour module and VU meter. The description suggests that the main purpose of the Chroma is the use for tracking and mixing, similar to the LTL Silver-Bullet

The Bart HRK MPQ568C is the colour format preamplifier with 2 colour module slots. It has the ultra-low noise, discrete class A, electronic ballanced input, microphone preamplifier and the additional ballanced active line/mix input. The EQ section has a HF and LF potentiometers with full boost/cut control in range of +/-15 dB per band. Each EQ band has 2 frequency settings. The MPQ568C has a balanced electronic output and is a cost-effective colour module platform designed for professional recording applications. The Line input with active attenuation circuit can be used for tracking and mastering. The microphone preamplifier delivers the noise performance of EIN:-129dBu at +65dB of Gain in full audio frequency range.

The Price Comparison:

The LTL Chroma is a sophisticated unit with input and output transformers and discrete opamps. Thus quite a high cost of the unit, ranging around 600USD, without included colour module.

The MPQ568C is a simple and effective design, focused on delivering key, high-performance features, such as low noise mic preamp and active line input. The cost of the MPQ568C, including 2 colour modules, is less than half-price of the single LTL Chroma unit.
