Main features of sp603
1.1 input and output:
Six channels of high-level input, six channels of low-level input, USB sound card input, optical fiber input, optional HD Bluetooth input (aptx, aptx HD, aptx LL) and U-disk playback input.
There are 6 analog power amplifier outputs, 2 digital power amplifier outputs (bridgeable), and 2 independent RCA outputs. Independent RCA outputs do not mix with power amplifier outputs.
1.2 the scheme adopts DSP of ADI company, model adau1452, codec adopts AKM multi-channel high-performance ak4612, and power amplifier adopts fully discrete design, which brings high performance, high signal-to-noise ratio and high fidelity.
1.3 DSP function:
High order matrix routing function, each output channel can choose the input signal source and set the mixing ratio.
10x31 section PEQ, multi slope high-low pass function.
10 channels of independent delay adjustment function.
1.4 output power (14.4V power supply, including line loss)
RMS: 6x55w (full class AB) +2x70w (discrete class D), 4 Ω, thd < 1%;
250W (discrete class D, BTL), 4 Ω, thd < 1%;
6x70w (fully discrete class AB) + 2x95w (discrete class D), 4 Ω, thd < 10%;
270W class D,BTL,4THD<10%
Peak: 6x140W@4 Ω (completely discrete class AB), 2x190W@2 Ω (discrete class D);
540W (discrete class D, BTL), 4 Ω;
1.5 perfect protection:

matters needing attention
4.1 for the sake of safety, it is not allowed to use a larger insurance without authorization. The standard insurance on the dedicated line should be 30A.
4.2 the 20pin special line has no power supply function. The power supply can only be connected to the Dian source line. The power supply wire diameter is not less than 14AWG of American Standard, and the output line diameter of power amplifier is many American Standard 20awg.
4.3 this product is only applicable to 12V power supply system of automobile.
4.4 power cord cannot be reversed, and it will not work after reverse connection.
4.5 digital power amplifier bridging does not support 2 Ω scenarios. If there is only 2 Ω subwoofer, it is necessary to reduce the volume of the bridge channel and set the low-pass no more than 150Hz until the maximum output power of the front stage is not protected.
4.6 when the DSP power amplifier is connected to more than 18V power supply environment, it will automatically mute and keep standby state, which meets the national standard GB / t28046.2-2011. When there is no sound output after the power amplifier is turned on, please check whether the power supply voltage exceeds the use requirements.
4.7 transient suppression P5 standard, according to the requirements of GB / t21437.2-2008, the default is p5a, 87V / 100ms / 8 Ω standard. If the generator voltage regulator of automobile is damaged beyond the range of transient suppression, the product may be damaged.
4.8 please configure ACC power on or high-level power on reasonably. If the configuration is not reasonable, DSP power amplifier will always be in the on state after the front mechanism, resulting in large standby current and switching impact sound.
4.9 Remo output, which can only be output after the DSP power amplifier is turned on and removed from mute. When the DSP power amplifier is turned off, the output will be cut off when the DSP power amplifier is turned off. The remo output capacity is limited and should not be used to drive other loads.
4.10 for low-level input, if the ground of Rac terminal contacts with the DSP power amplifier shell, there may be "aircraft sound". Please replace the RCA wire that will not contact the power amplifier shell.
