McIntosh range
MI347
The McIntosh MI347 is a 7-channel power amplifier intended for a coherent multichannel cinema rack where channel matching and installation efficiency matter.
Where it fits best
A single rack amplifier deliberately giving more power to LCR than to surround/height channels.
What to pay attention to
Its channels are not identical. Wire the three high-power outputs to LCR and document the four lower-power assignments.
