Audiopeak DSP4.16 High Power Good Price Amplifier-Four Channel 10000 Watts (4*2500W) for Distortion Free and Clear Sound 2u Chassis Professional Power Amplifi

Brief introductionTinboo electronics DSP series is a very dynamic and cost-efficient amplifier controlled by built-in digital process signal(DSP) module. its unmatched performance covers two models of 3000W, 4000W per channel at 4 ohms.Built-in smart DSP includes crossovers, EQ filters, delay and  limiting. Computer connectivity via Rs485  allows fast setup and configuration . with software.  ModelAmplifier outputDSP channels4 OhmsDSP4.1642in 4out3000WDSP2.2022in 2out4000W2, Features:SMPS for low heat consumption and universal power supplyIndependent class D amplifier module for each channel output .Display and select button for fastly choose DSP preset.DSP functions: Noise gate,gain,phase,mute,PEQ,Delay,,LimiterFull protection: Over AC voltage; troublesome signals ; DC; thermal; short circuit; mute           at power on/off   Amplifier section  ModelDSP4.16DSP2.20  Amplifier channels42  Output power /ch(1% THD+N, 1kHz @ 8ohm)4ch*1600W2ch*2000W  Ouput power /ch(1% THD+N, 1kHz @ 4ohm)4ch*3000W2ch*4000W  Frequency response (±0.5dB)@ 1 W, 8 ohms20Hz-25Khz  Sensitivity(@ 8ohms)1.2V  Slew rate (@ 1 kHz)50V/us  THD+N(1kHz @ 1W)< 0.05%< 0.05%  Cross talk(@ 1kHz)> 75 dB  Damping factor>400   S/N rate (20 Hz - 20 kHz, A weighted)>105dB  Power supplyHalf-bridge SMPS 160-240 V ±10%, 50-60 Hz  DSP Section  DSP channels2in-4out2in-2out  AD/DA converters24-bit,∑-△ AD/DA,48kHz sampling rate  AD/DA dynamic range115dB  Memory/Presets5 pre-set as user applications,30 pre-sets laptop memory  DSP function:ADI Audio DSP, Input channel:Noise gate,gain,phase,mute,4 bands of PEQ.    Output channel:LPF/HPF,Delay,Phase,Mute,Limiter,9 bands of PEQMax delay 8.29ms(sampling rate: 48K)  S/N rate>90dB  CrossoverButterworth,Linkwitz-Riley, Bessel,6dB/oct , 24dB/oct  Physical Section  Input connectorsAnalog input (2 * XLR-F, Link 2 * XLR-M)Analog input (2 * XLR-F, Link 2 * XLR-M)  Network connectors2 x RS485 port2 x RS485 port  Output connectors4 x speakON NL42 x speakON NL4  Dimension W*L*D(MM)483*390*88483*390*88  N.Weight(KG)1312       How do I match my speakers to my power amp?A general rule for choosing an amplifier is to select an amp that provides 1.5-2 times the continuous power rating of your speaker. This will ensure the speaker has enough power while leaving yourself 3 dB of headroom.How do STEREO, PARALLEL, and BRIDGE modes operate?STEREO: Each channel operates independently. Input signal and attenuator are also separated between each channel.PARALLEL: Input signal is connected to only a single channel, and the same output signals are obtained from two adjacent channels. Attenuator operates independently.BRIDGE: Two channels of power amp output work as a single channel with doubled output. Only a single attenuator operates. The voltage gain will be increased by 6dB, and the minimum load impedance will be doubled. For details on connecting the speaker output, please refer to the manual that came with each power amp.  What is rated output power?Rated output power is the RMS (root mean square) or effective value of electric power that can be delivered continuously for several ten seconds to few minutes. The unit is W (Watt).It is not a value that can be output continuously for a long period, but it would not matter in a practical operation because music signal and voice speech signal are generally not constant in level. When a signal like continuous sine wave is continuously driven at the rated output, the thermal protection circuit will be activated, which will reduce the output power to around 1/8 (-9dB).  What is input sensitivity?it is the required input signal level to obtain the rated output when attenuator is in its maximum (generally 0dB). It also means the output signal will be clipped if a signal larger than the input sensitivity is being input with the attenuator at maximum. When the voltage gains are the same, the larger output model is, the larger its input sensitivity is, too.If the load impedance is halved, the output power will be almost doubled since the voltage gain is constant. In this case, however, the input sensitivity will be a little smaller because the actual rated output will not be doubled.  What is the maximum input level?The maximum input voltage that can be applied to the device without any clipping. The unit is mostly dBu.If the input signal exceeds the value, it will be clipped even when the attenuator is turned down.  What is S/N ratio?The difference between maximum output level and the background noise level without input signal in the unit of dB. The larger the value, less affected by noise, ie. better performance.Generally, there is not much difference between the noise levels in the same series of power amps, so the model with larger output has better S/N ratio.  When rack mounting multiple power amps, is it necessary to leave space between each amp for heat dissipation?Current models for all Yamaha power amps have cooling fan installed. Therefore, as long as the front and back of the rack are
