8 channel amplifier
Class D technology
Integrated 12 channel DSP
Up to 480 Watts total power

Overview Mosconi Pico 8|12 DSP

Perfect OEM integration

Powerful DSP amplifier optimized for factory radio use. Four analog inputs, flexible routing, 3 x input EQ and delay. With 8 x 50 Watts ideal for active multi-way systems and extensive installations. Ready for the future with two digital inputs (SP-Dif and BT+) and two processed line outs.

Signal controlled power supply

In contrast to Class G/H, the power supply is only switched on when required (high levels) and regulated depending on the power demand. Benefit: The quiescent current is between 250 mA and 450 mA (depending on the speaker circuitry) -> Especially interesting for electromobility and motorhomes

Transducerless High-Speed PWM Power Amplifiers

High-efficiency PWM amplifiers with the fastest carrier frequency in the world today (> 2 MHz), enables HiRes audio transmission and the extremely small size. The modulation is done without DAC directly from the 96 kHz TDM signal of the DSP, thus the noise floor is close to zero and THD+N ~ 0.02 % / 1 W.

Input:

4 x analog inputs balanced (high-level) up to 30 V
2 x analog inputs switchable (high level / low level)
1x digital input SP-Dif optical (8 kHz - 96 kHz sampling rate)
1 x bluetooth port with SP-Dif - TTL (8 kHz - 96 kHz, e.g. for Mos AMAS bluetooth streaming module)
Bluetooth extended digital audio port (BT+)
(flexible 8 kHz - 384 kHz synchronous digital input for audio sources with 2 - 16 channels, direct DSP access without jitter, e.g. for MOS BTS-LD4C BT streaming module or extended analog inputs)

DSP:

294.912 MHz, 32-bit audio port, 64-bit core
Double precision 56 bit filter calculation
3072 SIMD instructions per sample at 96 kHzASRCs from 1:8 up to 7.75:1 ratio and 139 dB DNR

Control:

1 x USB serial data (connection PC / GUI)
1 x remote connector (connection for RCD, RC-Mini, RTC-Hub)
2 x bluetooth control port (connection MOS-BT3.0 (app control), RC-Can (CAN bus control)
1 x remote out, 1 x remote In, auto-remote with highlevel connection
Connections with MOLEX® plug contacts
Very small size with low heat generation, best suited for installation behind cladding

Software:

3 x 9 band parametric input EQ (de-equalizing)
6 x input delay 0 - 3ms / 0.01ms (de-delay)
10 x input level control digital (signal conditioning)
Flexible mixer for signal routing
(side separated, can sum and subtract, 10 inputs to 4 x 2 output groups)
6 x 30 band or 4 x 30 band + 2 x 15 band group EQ
(parametric, relative phase remains stable)
12 x 10 band output filters
Highpass / lowpass / highshelf / lowshelf / notch / allpass 1st + 2nd order / speaker-EQ)
12 x speaker delay 0 - 12 ms, 0.01 ms
12 x speaker phase switch
