The EP 4 is an amplifier designed to reproduce any musical genres: thanks to its four separate channels, it provides many different system configurations.
Pre-amplified inputs as well as hi-level inputs offer the possibility for the EP 4 to be interfaced with any head units, including factory OEM sources.
EP 4 boasts extreme reliability thanks to the use of FR-4 double layer PCB material. 70�m thick copper traces in combination with robust copper bars are used for paths with high current transfer.
The B channels feature Bass Boost adjustable within a range of 0 � 12 dB at 45 Hz to offer a deep, solid bass with control. Advanced electronics and optimized cooling system allow the EP 4 to provide high power, even under difficult conditions.
The Hertz EP range of amplifiers destroy age-old perceptions of what a consumer can expect at a certain price point. Hertz EP rewrites the rules of what to expect from an entry-level amplifier!
With lots of filtering combinations built-in, the EP range is never stuck for a solution despite its affordability. A perfect match for Hertz subs and speakers, the high-tech finish overcomes any shyness of putting these amps on-show and the fundamental design philosophy means they will perform flawlessly for many years to come.
Power Hertz EP 5, 5 channel Rp 4.900.000
Spesifikasi : 4x60w + 1x160 W @ 4 ohm
4x95w + 1x250 w @ 2 ohm







1 FR-4 dual-layer 70μm copper thick PCB and robust copper bars for high current transfer,
shorter audio signal paths and high reliability.
2 Output stage based on High Current & Power Dissipation SANKEN TO3P transistors.
C channels, dedicated to the subwoofer, are realized with single hi-power output stage
instead of bridged internal configuration of traditional designs offering higher power and
control on the subwoofer speaker.
3 Dual separate power supply stages for A, B channels and C channel based on Multi-winding
toroidal transformer and Low ESR 105�C resistant electrolytic capacitors.
4 Special pseudo-balanced dual input circuitry to reject electromagnetic disturbances present
on the Pre-amplified or Speaker-In.
5 Pre-amplified and Speaker-In allow interface with aftermarket or OEM sources.
Speaker-In are provided with compact “install-friendly” connector.
6 ARTTM-Automatic Remote Turn-On/Off function turns the amplifier on and off in perfect sync
with the source, eliminating the need for a remote signal when using the Speaker-In.
Remote Out signal is also provided to turn on/off other components installed in the system.
7 Flexible crossover system allows full range or hi-pass 12dB/Oct. filter on A & B channels for
front plus rear configuration and lo-pass 24dB/Oct. filter on C channel for optimal subwoofer driving.
8 3-Channel mode switch is provided to easy set up the amplifier for high power front speaker
system plus subwoofer to achieve up to 190W x 2 (4Ω) + 250W x 1 (2Ω).
