We are pleased to announce the release of the Dolby® Multichannel Amplifier DMA16301, an updated 16-channel amplifier with enhanced power handling for lower impedance loudspeakers. The DMA16301 complements the existing 24- and 32-channel amplifiers, the DMA24300 and the DMA32300, respectively. The updated DMA16301 offers improved performance that enables it to better support a broader range of loudspeakers in an auditorium, including screen channels, low-frequency components and subwoofers. Additionally, it now integrates with traditional 5.1/7.1 cinema processors, such as the Dolby® Digital Cinema Processor CP750, via a qualified external analog-to-digital converter, the Yamaha Tio1608-D. The DMA amplifiers now support the following output power:
Output mode | Speaker impedance | DMA24300, DMA32300 | DMA16301 |
stereo output mode (unbridged) | 2 ohm | N/A | 600W |
4 ohm | 300W | 600W | |
8 ohm | 300W | 300W | |
bridged output mode | 2 ohm | N/A | N/A |
4 ohm | N/A | 1100W | |
8 ohm | 600W | 1100W |
We are also announcing the release of the Dolby Multichannel Amplifier software version 2.0.0, which is compatible with all DMA hardware. This software release adds the following new capabilities:
