Channels 7 Channels: Not stated in the record Not stated in the record
Power, 8 Ω, all channels driven Not stated Marantz publishes no all-channels-driven rating (online manual and product page read 2026-09-26). ASR measured 2 channels only. The 35 W figure this record carried before 2026-09-26 was an estimate (about 70% of the 2-channel rating), not a measurement and was removed. —
Power, 4 Ω, all channels driven Not stated Marantz publishes no 4 ohm rating and no all-channels-driven figure. —
Rated power, 8 Ω 50 W load: 8 ohm · channels driven: 2 · thd limit: 0.08% · bandwidth: 20 Hz - 20 kHz Rated power, 8 Ω: Manufacturer, Marantz CINEMA 70s online manual, Specifications: Audio section Manufacturer, Marantz CINEMA 70s online manual, Specifications: Audio section, Document ↗
Rated power, 4 Ω Not stated Not emitted. Marantz rates 6 ohm, not 4 ohm. ASR measured 85 W (knee) / 92.6 W (1% THD) into 4 ohm with 2 channels driven, but at 4 ohm the unit dropped into a higher-distortion mode after about 2 minutes at 5 W and higher-level sweeps tripped protection that needed a power cycle (ASR review, 2023-12-11). A 4 ohm figure would overstate what it sustains. —
Bridgeable Not stated the record carries no bridging statement, and Marantz's document was not re-read this round —
Bridged power, 8 Ω Not stated bridging is not on the record, so no bridged figure is emitted —
Bridged power, 4 Ω Not stated bridging is not on the record, so no bridged figure is emitted —
Bridged minimum load Not stated bridging is not on the record, so no bridged figure is emitted —
