ARC Audio XDi Amplifiers.

New from ARC Audio, these amplifiers are fully featured, tiny in size and have great power.

The Range.
XDi 804 4ch, 4x80w or 2x240w RMS, remote sub control, size: 206 x 165 x 57mm $499 rrp.

XDi 803 3ch, 2x80w + 1x400w RMS, remote sub control, variable sub phase, size: 247 x 165 x 57mm $549 rrp.

XDi 805 5ch, 4x80w + 1x400w RMS, remote sub control, variable sub phase, size: 285 x 165 x 57mm $699 rrp.

XDi 600.1 Mono, 1x400w @ 2ohm, 1x600w @ 1ohm RMS, remote sub control, variable sub phase, size: 247 x 165 x 57mm $499 rrp.

XDi 1000.1 Mono, 1x700w @ 2ohm, 1x1150w @ 1ohm RMS, remote sub control, variable sub phase, size: 285 x 165 x 57mm $649 rrp.

All models feature:
Built in x-over functions (HP/LP 50-250Hz),
Bass boost (+15dB @ 45Hz - 804, +15db variable 40-100Hz - 803 & 805, (+18dB variable 40-100Hz - 600.1 & 100.1),
Built in fuse protection,
Small footprint for multi fit installation possibilities.

The Design.
-Hybrid D class output design with discrete Subwoofer output channel (3 & 5 channel models).
-High Frequency switching power supply allows for greater separation from audible listening frequencies increasing sound quality and lowering THD.
-Input Inductor power supply isolation protects from unwanted interference in AM/FM reception.
-Ultra Low ESR high capacity power supply storage bank covers potential fluctuations in power supply demand, increasing efficiency and sound quality.
-Phillips chip based Class D Technology powers all multi channel XDi amplifiers, producing little or no heat.
-Embedded protection circuits including Thermal, Current Limit, Rollback DC Offset, Reverse Polarity and Overvoltage.

Do you know what the XDi 805's speaker channels bridge to at 4ohms? Just out of curiosity

The XDi 805's speaker channels are rated at:
4x 80w @ 4ohm,
4x 120w @ 2ohm and
2x 240w @ 4ohm bridged.

So you could set it up as a 3 channel system with 2 x 240w for the fronts and 1 x 400w for the sub.

What power does the 5 channel's mono stage make at 2ohm? Also, is it 1ohm stable?

The 805's sub channel is rated at 400w RMS @ 2ohm. 1 ohm is not recommended.

Ah okay thanks for that. Looks like great amp to power a whole system!
