Page 9: Noise Generator
Signal Routing The MDA-KDM series power amplifiers have a 4X4 input/output routing matrix (with the exception of the MDA2- 8KDM, that has a 2x2 matrix), allowing users to mix, with a suitable level, any input signal into one or more output channels. - Page 10 Digital power amplifier MDA-KDM series Level monitoring interface The level monitoring interface shows input and output channels level meter, as well as the main amplifier status information. It also allows to set channels gain and mute. The Vu-Meter section shows the level of the inputs (before gain “BG”) and of the outputs (after process “AP”) Input and output channels level can be adjusted within the range -12dB~+12dB with a 0.1dB step.

Digital power amplifier MDA-KDM series NOISE GATE The noise gate is the first process in the input signal path. To enable the process, click "OFF" / ”ON” button. In the “Noise Gate” frame, the main parameters can be set: Threshold: it represents the signal level below which the noise gate “close” (mute) the input channel. - Page 15 Digital power amplifier MDA-KDM series Each input channel of MDA-KDM amplifier has 12 PEQs, that can be set as Bell, High-Low shelving, High-Low pass (Butterworth -12dB/Oct), notch and all-pass (1 order) Output Channel View www.marani-proaudio.com E-mail: info@marani-proaudio.com...
- Page 16 To this end, Marani's proprietary MIR filters integrates advantages of both IIR and FIR based Xover, since they provide the same magnitude response of the IIR and a linear phase as the FIR, with a low latency value.
- Page 17 Digital power amplifier MDA-KDM series FIR Xover. It supports high/low/band pass linear phase filters and offers a full set of parameters (number of taps, stop-band attenuation, window type) to customize di filter generation. A third-party FIR filter file can also be imported (CSV, TXT or SAF files are currently supported).
- Page 18 Digital power amplifier MDA-KDM series The output section of the MDA-KDM amplifier provides 8 PEQ filters. Available filter type are: Bell, Hi-Shelving 1st order, Hi-shelving 2nd order, Hi-shelving Q, Lo- Shelving 1st order, Lo-Shelving 2nd order, Lo-Shelving Q, Low Pass 1st order, Low Pass 2nd order, Low Pass Q,...

Page 19: Amplifier Calibration
The calibration of the MDA-KDM series amplifier does not require any acoustic microphone or sound card. Simply connect the amplifier to the speaker and follow the steps below to complete the calibration. - Page 20 Digital power amplifier MDA-KDM series During the calibration, the power amplifier will emit a -18dBu sine sweep signal. ③ ④ When the calibration is completed, the system adds the new amp calibration in the speaker library. After calibration, the user can also verify the amplifier response, by selecting the speaker in the library and clicking the VERIFY button.
- Page 21 MDA-KDM series AEQ – Preface MARANI AEQ (Auto EQ) is an application, developed by Marani Pro Audio in Italy, for performing Acoustic correction of loudspeaker and room responses using DSP based approaches. This tools allows to perform an impulse response measurement of speaker or room and then to design the optimal equalization filter.
