Dubbed the DTA-70.1, the new 9-channel home theater power amplifier is rated at 150 watts per channel and, according to Integra, it’s the industry’s first 9-channel power amp specifically designed for home theater apps. After being tested by THX, the Integra DTA-70.1 was awarded their top-level THX Ultra2 certification, supposedly indicating its ability to drive all of the speakers in a modern nine-channel home theater system to full THX output levels and beyond.
The $1800 priced DTA-70.1 is an all-analog discrete-component power amplifier with a giant power supply and balance line inputs (Huh? Yep, balanced!). Each channel has identical symmetric circuit layouts, configured in a push-pull topology utilizing high-performance three-stage inverted circuitry and what Integra claims is custom-designed output transistors.
The large (giant), 11.7-Amp power supply of the DTA-70.1 uses a massive toroidal power transformer with dual 22,000 µF capacitors with an FTC Dynamic Power specification of 180 Watts into 8 ohms, and 400 Watts into 3 ohms. The power bandwidth is 5 Hz to 100 kHz, +/-3dB, and the IHF A-weighted signal to noise ratio is an excellent 110 dB.
