Parasound ZM12 Professional 12-Channel 2RU Amplifier – Pascal Class D Technology

Description Delivering unmatched power, flexibility, and efficiency, the Parasound ZM12 is a 12-channel, 6-zone amplifier designed for large-scale audio installations. Built to handle complex, multi-room systems, the ZM12 packs robust power into a compact 2RU chassis, making it perfect for custom installations, commercial audio, or multi-zone residential systems.Combining a Class AB input stage with premium Class D output modules, the ZM12 is stable down to 2 Ω and engineered for both performance and reliability. It offers independent level control for each channel, A/B speaker outputs (up to 24), and multiple trigger and input options to integrate seamlessly into any automation or distribution system. Each zone supports its own auto-on trigger and can switch between stereo or summed mono, giving installers flexible control over how the system is configured.Whether you’re powering a home theater, restaurant, retail space, or whole-home audio system, the Parasound ZM12 delivers consistent, high-performance sound with minimal heat, low power consumption, and exceptional build quality.Features of Parasound ZM1212 independent channels across 6 zones — supports multi-room installationsHigh-power Zone 1 (channels 1 & 2) — 120 W into 8 Ω, 150 W into 4 Ω or 2 ΩLower-powered zones (2–6) — 60 W into 8 Ω, 100 W into 4 Ω or 2 ΩClass AB input Class D output — efficiency clean sound2 way speaker outputs (A/B) — up to 24 speaker terminals for flexible wiringPer-zone 12 V triggers audio-sensing — automation-friendlySpeaker-level input — integrates with systems without preamp outputsSummed Mono mode — ideal for single-speaker zonesShort-circuit & overheat protection — with front-panel indicatorsLow standby power — only 0.5 W, energy efficientCompact 2RU chassis — saves rack space while offering 12 channelsSpecifications of Parasound ZM12SpecificationDetailsModelParasound ZM12Channels / Zones12 channels / 6 zonesPower Output (Zone 1 – Ch. 1 & 2)120 W ×2 @ 8 Ω; 150 W × 2 @ 4 Ω or 2 ΩPower Output (Zones 2–6 – Ch. 3–12)60 W ×10 @ 8 Ω; 100 W ×10 @ 4 Ω or 2 ΩMinimum Speaker Impedance2 Ω (A B outputs)Amplifier ArchitectureClass AB input Class D outputFrequency Response20 Hz – 20 kHz, 0 / –0.25 dB; 5 Hz – 50 kHz, 0 / –3 dBTotal Harmonic Distortion (THD)< 0.05% at typical listening; < 1.0% at full powerInterchannel Crosstalk~70 dB @ 20 kHzTotal Gain29 dB (level controls at max)Signal-to-Noise Ratio (SNR)> 112 dB (IHF A-weighted, input shorted)Trigger Options6 × 12 V DC inputs, 6 × looping 12 V outputs, master 12 V trigger, audio-sense per zoneInput OptionsRCA line-level bus 1 & 2, speaker-level inputOutput ModeStereo / Mono per zone (summed mono)ProtectionOverheat & short-circuit, front-panel indicatorsPower ConsumptionMax: ~1,550 W; Typical (all zones active): ~150 W; Idle (all zones): ~55 W; One zone: ~15 W; Standby: ~0.5 WAC Voltage100 – 250 VAC, 50/60 Hz (auto-switching)Dimensions (W × H × D)437 mm × 89 mm × 369 mm (2RU)Depth with Cables406 mm approx.Weight9.5 kg / 21 lbs net
