A first upgrade was offered to add Dolby Pro-LogicII, DTS Neo:6 and DTS-ES as well as AAC.

A later upgrade brought it up to THX Ultra 2 and DTS-ES 96/24.

Seems identical to Integra DTR-9.1.

Power rated at 11A.

Despite using the Integra sub-brand in Japan, the receiver was only released under the Onkyo banner in the US. Instead, the US Integra (a separate label from Onkyo) received their own version of the amplifier through the Integra DTR-9.1.

Includes R1 plug to enable operation of Onkyo equipment that carry the R1 plug with the included receiver remote.

Enabled with line-out Zone 2 Multiroom output to enable the remote to be used anywhere in the course if the proper adapter is connected.

The headphone output on the front can be used to listen to a fold-down of the surround outputs normally outputted to the surround speakers.

Uses a spring clip for compatible AM antennas and a 75 ohm jack for FM antennas.

Also carries Re-EQ settings despite not advertising such features.

Note: on default settings, all LaserDisc functionality (including AC-3 decoding) are assigned to input 4. This means that any DD tracks fed through the AC-3 RF input will only work on A/V input 4 by default. This can be changed in the settings to accommodate your setup.

For a look at the upgraded versions (albeit in Japanese), see Onkyo Integra TX-DS989 Ver.2 and Onkyo Integra TX-DS989 Ver.3 for details.
