All adjustments are made via its front knob, no computer is necessary. All adjustments happen in real-time. 6 input channels and 6 output channels. Integrated Preamplifier: it can increase the signal voltage at its input and take it up to 5 Volts RMS without distortion. Signal level inputs (RCA) and high inputs through the included multi-connector. When the high level inputs are used, Merlin will automatically turn on when sensing an audio signal, and will additionally create a Remote output to turn on external amplifiers. Input channels can be summed. For each output channel, it is possible to select where its audio signal will be taken from, without limitations, it includes all the possibilities! Non-volatile memory: the settings made are not lost if the device runs out of power or even if it is removed from the car. COPY and LINK function for two channels at a time. Each channel can be individually attenuated in multiples of 0.5 decibels. It is possible to select for each channel either a High-Pass, Low-Pass, or Band-Pass filter. In the case of subwoofers, the application of a Band-Pass filter would behave like a normal Low-Pass plus a Subsonic (Infrasonic) filter. The cutoff frequency (F3) of each filter can be adjusted in multiples of 1 Hertz, from 21 to 19,999 Hertz. The attenuation slope for each filter can be 6, 12, 18, or 24 decibels per octave (1st, 2nd, 3rd, or 4th order). It is possible to vary the output phase of each channel between 0 and 180 degrees. It has independent time delays for each channel. 15-band Fully Parametric Equalizer per channel (allows you to adjust the 3 parameters: Frequency, Gain and Bandwidth): the Center Frequency of each band can be set between 20 and 20,000 Hertz with a resolution of 1 Hertz. It has 6 non-volatile memories.
