DP series digital 1U power amplifier

 The T.I Pro Audio 2018 DP Series of Professional Power Amplifiers is a new milestone for Class D 

amplifiers. The advanced Class D power amplifier module and the highly efficient SMPS power 

module make the DP Series extremely efficient and reliable with extremely high power density and are available only in 1U of space at a standard depth of 9 " Unprecedented super power.

Features

 1U height 9 "depth standard chassis, compact, lightweight;
 Class D power amplifier module with fixed switching frequency;

 Active Power Factor Correction (PFC) for stable operation over full voltage (90-264V)
High efficiency speaker back EMF absorption system;
unique clipping limiter;
 temperature-controlled variable speed fan, airflow from front to back circulation;

 backplane with input sensitivity selection switch (0.775v / 1v / 32dB);

 full circuit protection, including: soft start, DC, subwoofer, high frequency, overheating, short 

circuit, power on / off mute;

Low-frequency vigorous powerful, very low dive depth, high-frequency mellow, transparent, clear;

amplifier module and power module integrated design, more than 85% of the devices using 

mechanical automation to ensure product consistency;

Applications

 KTV / bar / video bar;
 meeting rooms / function rooms / cinema;
 mobile performance / portable sound reinforcement;

Power Parameters EIAJ Test Standard, 1 kHz, 1% THD

Perfect reliability Protection measures:

The DP Series power amplifiers have excellent reliability protection that protects the power amplifier from damage in the event of a misuse and protects the speaker system connected to it.

Soft Start, DC, Secondary Audio, HF, Overheating, Short Circuit, Power On / Off Mute;
Soft-start: Non-contact soft-start circuit can effectively inhibit the switching power supply to the grid when starting the impact of the surge.

DC protection: If the output signal with a larger DC voltage, in order to protect the woofer from 

damage, the machine has a limited DC output protection;

Secondary audio protection: If the output signal with a substantial second audio signal,

in order to protect the woofer from damage, sub-audio protection circuit will be protected;

High-frequency protection: long-term input signal above 10kHz, in order to prevent damage to the amplifier and tweeter, the 

amplifier will automatically attenuate the input signal, limiting the output power.

Overheat protection: the amplifier to work in a limited temperature range, if the amplifier internal 

radiator temperature exceeds 85 ℃, the output power will be automatically reduced (the working 

condition at this time known as power compression), the temperature inside the machine graduallydecreased. If the power after the compression temperature can not fall below 95 ℃, the amplifier 

will stop running until the temperature inside the machine down to 75 ℃ below the temperature 

will automatically reset operation.

Short circuit protection: amplifier external load system short circuit (protection threshold is less

 than 1.0 ohms), the power amplifier to prohibit the output. After short circuit troubleshooting, the power output is automatically restored immediately.

Power on / off mute: Power amplifier will instantly mute the power switch, so you can effectively 

avoid the power amplifier to switch the speaker to the abnormal impact

   For example, we strictly control the voice coil wire purity level,especially in the voice coil made of glue when we certified by the EU more than 220 degrees Celsius, 100  hours of power test,can provide relevant information parameters.Our usual cone of high- quality British UKN cone,he can better restore and release sound. We use a magnet Y35 quality international standards.T Washer We use top electrical iron, 900 degrees C after 8 hours-temperature annealing processing, so that the carbon content close to zero. Our Speaker Box frame belongs to our specially treated surface temperature electrostatic spray, and balanced treatment, such as selvedge position plucked location,location washer, we use CNC lathe finishing to ensure that the speaker is not at work There is an equilibrium problem. We open with a mold clamping, so that the speaker does not work exist selvage shedding problem.
