Product Overview

The Hertz DP 2.200 is a compact fully bridgeable 2-channel Class AB amplifier from the Dieci Power Series, engineered to deliver maximum power output in a minimal footprint suited to modern vehicle installations including factory amplifier locations. The amplifier operates in 2-channel or bridged 1-channel configuration, with output power of 80W x 2 at 4Ω and 110W x 2 at 2Ω in stereo mode, and 220W x 1 at 4Ω in bridged mono mode at 1% THD. Maximum musical power is 260W total at 14.4V.

Hi-Res Audio certification with a 10Hz-45kHz bandwidth at -3dB ensures faithful reproduction of high-resolution audio sources. Speaker-In inputs with 1.6-40Vrms sensitivity and integrated USS (Universal Speaker Simulator) technology enable correct connection to OEM head units with speaker load detection. Pre-In inputs cover 0.32-8Vrms. Balanced input circuitry on both Pre-In and Speaker-In provides high noise rejection. Automatic Remote Turn-On/Off is triggered by OEM radio speaker output at 1.5V DC. Full-range pre-outs are available from both Pre-In and Speaker-In modes. Adjustable high/low-pass crossover filters at 50-4000Hz 12dB/Oct. and 0-9dB bass boost at 50Hz. Operating voltage 6.5-16.5V DC with nominal 2 x 20A fuse. Dimensions 240 x 202 x 50mm. Weight 1.95kg.

Features & Benefits

Hi-Res Audio Certification - 10Hz to 45kHz Bandwidth: The DP 2.200 holds Hi-Res Audio certification with a frequency response of 10Hz to 45kHz at -3dB, ensuring faithful reproduction of high-resolution audio sources well beyond the standard 20kHz upper limit of CD-quality audio.

Fully Bridgeable 2-Channel Class AB - 2Ω Stable in Stereo: The fully bridgeable 2-channel Class AB topology delivers clean, efficient power in stereo (2Ω stable) or bridged mono (4Ω stable) configurations, providing flexibility for full-range stereo speaker systems or single subwoofer applications.

260W Total Maximum Musical Power: The DP 2.200 delivers up to 260W total maximum musical power across its output configurations, including 260W x 1 bridged at 4Ω at 14.4V.

Universal Speaker Simulator (USS) Technology: The integrated USS technology enables the DP 2.200 to be correctly connected to OEM factory head units with speaker load detection, presenting the correct low-impedance load on the speaker outputs to keep the head unit audio enabled during integration.

Speaker-In with Balanced Input Circuitry - 1.6 to 40Vrms: The Speaker-In input accepts 1.6-40Vrms with balanced input circuitry for high noise rejection, enabling direct connection from OEM factory head unit speaker outputs across a wide range of factory output levels.

Automatic Remote Turn-On/Off from OEM Speaker Output: The ART feature activates the amplifier automatically from the OEM radio speaker output signal at 1.5V DC, eliminating the need for a dedicated remote wire in factory head unit integration installations.

Adjustable High/Low-Pass Crossovers - 50-4000Hz 12dB/Oct.: Adjustable high and low-pass crossover filters (50-4000Hz, 12dB/Oct.) provide flexibility for configuring the amplifier to drive full-range speakers, tweeters, or subwoofers across the available filter range.

0-9dB Bass Boost at 50Hz: The adjustable bass boost provides up to 9dB of gain at 50Hz for additional bass emphasis when driving subwoofer loads in bridged mono configuration.

Full-Range Pre-Outs from Both Input Modes: Full-range pre-outs are available regardless of whether Pre-In or Speaker-In inputs are in use, enabling connection of additional downstream amplifiers or signal processors.

Ultra-Compact Design for Modern Vehicle Installations: The 240 x 202 x 50mm form factor is engineered for installation in the narrow spaces of modern vehicles including factory amplifier locations under seats and within door panels.

Elegant Design with Removable Top Panel: The machined terminal block, status LED, and removable top panel protecting controls and connections provide a premium appearance and functional protection.

Technical Specs

Compatible With

The DP 2.200 is compatible with 6.5-16.5V DC vehicle electrical systems. Speaker-In inputs with USS technology and ART automatic turn-on enable direct integration with OEM factory head units. Pre-In inputs support aftermarket head units and signal processors. Full-range pre-outs allow connection of additional downstream amplifiers. Confirm speaker impedance loads match the supported minimum impedance (2Ω for stereo, 4Ω for bridged mono) before purchase.

Frequently Asked Questions

What is the DP 2.200 rated at in bridged mono mode?

In bridged mono mode at 4Ω, the DP 2.200 is rated at 220W x 1 at 1% THD, or 260W x 1 at 10% THD and 14.4V DC, making it well suited to driving a single subwoofer.

What is USS technology and why does the DP 2.200 need it?

USS (Universal Speaker Simulator) presents the correct low-impedance load to OEM factory head units with speaker load detection, which monitor for a speaker load on their outputs before enabling audio. Without USS, connecting a high-impedance amplifier input directly to the factory speaker output can cause the head unit to mute. USS resolves this, enabling clean OEM integration without additional adapters.

Does the DP 2.200 require a remote wire for turn-on?

Not necessarily. The ART feature activates the amplifier automatically from the OEM radio speaker output at 1.5V DC, eliminating the need for a dedicated remote wire in OEM integration installations. A conventional remote wire can still be used when installing with an aftermarket head unit.

What is the difference between the DP 2.200 and the DP 4.300?

Both are from the Hertz Dieci Power Series with the same design, USS technology, ART turn-on, Hi-Res Audio certification, and crossover features. The DP 2.200 is a 2-channel unit delivering up to 260W bridged mono at 4Ω. The DP 4.300 is a 4-channel unit delivering up to 420W total in 4, 3, or 2 channel configurations. Choose the DP 2.200 for a compact stereo or mono subwoofer amplifier; choose the DP 4.300 for a full 4-channel system or 3-channel configuration.

Is the DP 2.200 Hi-Res Audio certified?

Yes. The DP 2.200 holds Hi-Res Audio certification with a frequency response of 10Hz to 45kHz at -3dB.
