• Over view

   P series power amplifier is properity of NingZi, beyond“AUDIO IS FIRST”design philosophy and through 3 years and base on the founder 21 years amplifier design experiences，now it is here.

P Sereis uss interleaving continuous conduction mode PFC technology where it compare to common products resulting much lower impedence at least 50% off, and second phase built-in LLC topology DCDC converter that gives better effecicey and less EMI, because of these the power supply gets great balance between components density and power density。

Total power output up to 10000W, flexible channels from 2-4 and power from 400W-5500W per channel, perfectly cover any audio application demands.

PPS^TM MOSFET over current protection system（pulse by pulse sense），PPS circuit will detect the current each pulse once the MOSFET is on that means if the MOSFET is working on 100KHz switching frequency then PPS is monitoring 100,000 time per every second, any of pulse happend, the PPS will act to protect the system health.

ACL^TM  limiter system（average current limiting），as well know audio amplifier is not playing the continuous signal only the music signal ( we say burst signal) , in fact the music signal is only 30-40% energy than the continuous signal, so once the amplifier ouput continuous current and over the setting then ACL system will judge that is un-normal in this case ACL will automaticlly limit the input sigal to reduce the output and keep the amplifier health. If the output current still getting raise, then the amplifier will shut down for 15 seconds and restart again.

DTS^TM  thermal management system（direct touch systme）, most of the over heat protection in audio field they only use simple way like a thermal switch putting on a heatsink or a NTC resistor near the MOSFET and we know heat transfer needs time and thermal switch or NTC resistor to get the reality thermal needs time too but for power device (MOSFET) the time is very cridical, DTS is right here to sort out this issue by putting a NTC resistor right to the thermal pad of MOSFET (the thermal pad is the internal heatsink of the device), the thermal route is much shorter.

International standard components are using, for instance TEAPO capacitors, Nichicon capacitors, FARA film capacitors, IXYS devices, 2OZ PCB, Micrometals and EPCOS magnetics, all Neutrik connectors, Canal switch, inductry grade 6063 aluminum and low impedence metal sheet for chassis.

P54.2/P26.4/P19.4 has variable indicators on the front like signal presenting, loading, cliping and output.

1.5 unit rack space gets the perfect balance between space and cooling.

• Specification

1. Manufacturer own the right to change the specifications without notice！
2. Output power meaurement standard ref to AUDIOPRECISION 《Paper-testing switching audio power amplifier》，burst sine wave singal 1Khzand 20ms, noted the THD less than 1%。
3. The amplifier power on by soft way，mean meas when you plug in the power cord the internal is live, please be sure and knowing。
4. Optional X series ( there is only panel differnect between X and P series)！

• Front panel description

1. TP2500 / TP4150/ TP4120  Front panel：

1. FAULT： Amplifier gets into protection or faulty mode，please switch off and contact your nearest after sales people。
2. CLIP： This shows the amplifier distortion，input signal too strong or wrong loading, please check the signal strength or the load。
3. LOADING：  Loading indicats，when amplifier runs with signal and connect the load，it will flash along with the output strength（starts at 0.5WRMS roughly）。
4. OUTPUT： When amplifier runs with signal, indicats the output strength, otherwise it is off，（starts at 1VRMS roughly）; otherwise it mutes or does not turn on。
5. SIGNAL： Indicates the input signal （it likes the Pre-fader display on a Mixer），brightness shows the input signal strength，starts at 0.07VRMS roughtly。
6. A/B/C/D： Volume control（Gain control），-80~0dB。
7. AC： When plug in the main power, LED is on，that shows users the amplifier internal is already live, please take care，when turn on the amplifier, LED will be off。
8. ON： Power on indicator，plug in the power cord and push the power switch then LED is on, ready to play。
9. POWER：Powe switch。
10. Cooling air enterance，please dont block and do maintennace regularly to avoid the amplifier enter thermal protection, make people un-happy；please noted, the X series amplifier has the enterance on the middle and both side of the panel。
