The ISA1350 Commercial 800W Power Amplifier from QSC is a 3-RU rackmount power amplifier designed specifically for sound contractors. It can be used as a low-impedance solution rated for 2-Ohm operation at 2000W per side, or 8 Ohms at 800W per side. The versatile loading options, feature set, and protection circuitry, in addition to the built-in HD-15 DataPortV2 DSP interface capability, ensures a high-value, cost-effective solution for budget-minded installations.

The ISA-1350 is housed in a rugged, all-metal chassis that features rear-panel gain controls for tamper-resistant operation and 2 dB detents for quick and repeatable settings. The inputs include both XLR and detachable Euro-style connectors and the outputs feature covered barrier strip connectors for full safety agency compliance.

Related Questions and Answers

Q: 1. Is this an original version of the amplifier with the fan speed control? The product image silkscreen seems to indicate this is NOS.

A: No, this is the current version of the Rane MA 3 Three-Channel Power Amplifier which does not offer control of the fan speed. The earlier version did have a two-way switch that allowed you to run the fan at normal or fast speed. According to Rane, it was seldom necessary, if ever, to run the fan at the fast speed, except perhaps in very hot environments when used for heavily compressed music into a demanding load. The downside of running the fan at the fast speed was noise. For that reason the current version does not include fan speed control and provides thermal management with a sealed heat-tunnel design incorporating low velocity forced-air and large aperture openings. This design minimizes the noise usually associated with forced air cooling and eliminates the need for an air filter. Forced air-cooling allows the amplifier to operate reliably in harsh environments and avoid the buildup of heat in unventilated racks.

Q: 2. I have the Ashly 8.2t+ passive speakers. Is this amp comparable for conference room sound reinforcement?

A: Yes the Rane Commercial MA 3 Amplifier is directly compatible with the Ashly AW 8.2T+ Passive 8" 2-Way Installation Speaker with Transformer (White, Pair) for conference room sound reinforcement.

Q: 3. HI, Is it possible to power my 200 watts speaker using Rane MA3?

A: This amp is 40-watts per channel, so it would not power 200 watt speakers. I would suggest a 200 watt amp, such as the ART SLA-2 - 2-Channel Rackmount Power Amplifier (200W Per Channel at 8 Ohms), BH #ARSLA2.

Q: 4. Can you hear the fans?

A: Hi, yes but the fans are designed to be very quiet on the QSC GXD 8. Thank you for shopping at B&H!

Q: 5. How loud do the fans get, do you hear them?

A: The Yamaha PX8 is made primarily for live sound reinforcement. In that environment, you would not hear the cooling fans in the PX8 amplifier.

Q: 6. How can I connect 6 speakers to a 2 channel amp?

A: Depending on the specifications of your speakers it may not be possible to connect 6 speakers to a 2 channel amplifier. This particular amp is not designed to accept less than a 4 ohm load per channel. For information or suggestions on connecting speakers to this amplifier, please contact a Pro Audio Representative here by phone at 800-606-6969 or email audio@a href= http://bandh.com target= _blank bandh.com/a

Q: 7. how many speakers can I connect per channel?

A: The QSC GX3 features 2 physical speaker outputs designed for optimal operation at 8 ohms. The unit is able to operate safely with a 4 ohm load as well which will give you a higher wattage output per channel. You are able to connect multiple speakers to each channel in parallel, but should be careful not to exceed the wattage and impedance ratings listed by the manufacturer.

Q: 8. Does it have fans to keep it cool?

A: Yes the Yamaha PX8 amplifier has cooling fans.

Q: 9. how do i set the jumpers in back i cant understand the diagram on the back?

A: The jumper settings on the ISA Ti will depend on the mode you are using the amplifier. Switch 1&2 correspond to the limiter and filter for channel 1, switch 9&10 correspond to the filter and limiter on channel 2. The center switches (3-8) set the amplifier mode: Stereo parallel or Bridged. Settings are shown on the rear panel diagram.

Q: 10. Does this include the rack brackets with purchase?

A: Yes. The rack mounting kit is included.
