The Integra DTA-9.4 is a 7-channel home theater power amplifier separate. It is a Class D switching amplifier with a higher efficiency, greater output capacity, and smaller footprint than a Class A/B amplifier. It is one of two current home theater "separates" from Integra and is designed to be coupled with the Integra DTC-9.8 pre-amplifier/processor. However, you can use this with any pre/pro separate or even an A/V receiver with pre-outs. The DTA-9.4 features 7 independent, full-bandwidth amplifier circuits, each with unbalanced RCA inputs, balanced XLR inputs, and speaker plugs. Each input and output connection is gold-plated, with the speaker output accepting thick spade plugs, heavy gauge speaker wire, and banana plugs. The manufacturer claims 120 Watts per channel into 8 ohm of RMS power when driving 2 channels.

  • 7 channel Class D switching amplifier
  • power: 120 Watts / channel RMS @ 8 Ohm (driving 2 channels), 240 Watts / channel @ 4 Ohm
  • power supply: high output current switching features 156,000 microfarads of capacitance
  • independent circuit topology
  • Integrates Integra's Vector Linear PWM (Pulse Width Modulation) to reduce noise that typically plagues switched MOSFET devices
  • price: $3000 (MSRP)
  • release date: May 2003
Release date and price

The DTA-9.4 was release in May 2003 and often coupled with the Integra DTC-9.4 preamp/processor. The DTC-9.4 has been superceded by the Integra DTC-9.8 featuring the latest HDMI, 1080p, and video scaling technology.
