Hi-Performance Hi-Value Electronics
The EP Energy-Power, series electronics are based upon 70m thick dual-layer PCBs made from FR-4 material, contributing to the EP series superior performance in terms of S/N Ratio and overall signal integrity. Employing FR-4 material with 70m thick copper traces ensures high reliability, and in combination with the robust copper bars where needed in the power supply areas, guarantees high current transfer, lowering the overall operating temperature of the amplifier. SANKEN TO3P high current bipolar transistors are used in the EP 2, EP 4 and EP 5, while the EP 1 D output stage is based upon multiple TO-247 Power MOSFETs each rated at 44Acurrent/380W. Low-loss multi-winding toroidal core transformers increase the amplifiers efficiency and current capability. Low ESR 105C high temperature electrolytic capacitors ensure optimal transient current response and performance over all load conditions.
The EP Energy-Power series can be interfaced with traditional pre-amp sources or speaker level OEM sources through an high noises rejection input circuitry. An install-friendly compact connector is provided for use with Speaker-In input. With the EP 1 D, a pre-amp output is featured that can be used to pass the same signal present at the Speaker-In input to other TM Turn-On/Off circuitry eliminates the need components in the system. ART - Automatic RemoteTM for a remote signal when using the hi-level inputs. ART automatically turns the amplifier on and off in perfect sync with the source, without the troublesome noise found in other designs. TM ART also provides a Remote Out signal to turn on/off other components installed in the system.

Thermal System

The unique anthracite mineral heatsink finish is achieved using a hi-tech scratchresistant paint. Besides having a high resistance to incidental contact and environmental conditions, this special finish also contributes to heat transfer, effectively increasing the heatsink area. Special steel springs are used to fix the power transistors, providing superior heat transfer from the device to the heatsink. The special split design provides precise pressure on each device, avoiding potential thermal issues caused by poor contact between the devices and the heatsink. Thanks to this detail, the thermal efficiency is increased, allowing the power devices to work with lower average temperatures.

Synchro D-Class

The EP 1 D is based on Synchro D-Class technology, where the Output Stage PWM Driver Module generates its own digital clock signal and also generates the clock signal used in the Power Supply PWM Driver. This circuit synchronizes both stages, avoiding potential noise generated within the audio band. The use of Synchro D-Class technology allows the EP 1 D to achieve an extremely high S/N ratio of 100dBA. Synchro D-Class technology also features a different feedback point from traditional Class-D designs. The feedback signal used is taken after the output filters stage, avoiding the non-linearity of the analog output filters, which degrade the performance of the output stage. This results in better control of the subwoofer, for tight controlled output.

EP LINK

EP LINK provides the ability to strap two EP 1 D into bridged mode to achieve up to 1700W (RMS) into a 2 ohm load. This circuit also allows the use of multiple pairs of EP 1 D. No external accessories are needed to realize the system. When operating in the EP LINK mode the first EP 1 D (Master) receives the input signal, with this exact signal, along with all of the control settings of the master passed to the second EP 1 D (Slave). This ensures that the two bridged amplifiers operate with the exact same output signal. The EP 1 D system brings you to the top of SPL competitions!
