Crestron AMPI-8150 8-Channel Power Amplifier, 150W/Ch., 4/8 Ohm or 100V, International, 220-240V

About the Crestron AMPI-8150

Each channel gives 150 W into 4 to 8 ohms or at 100 V, and can be configured individually in software for Lo-Z or Hi-Z use. Channels can run in mono, or adjacent pairs (1 and 2, 3 and 4, 5 and 6, 7 and 8) can be set for stereo or bridged operation, with 300 W per bridged pair into 8 ohms. Class D technology keeps power consumption and heat down, and the internal power supply includes power factor correction.

Eight balanced line inputs on 3-pin 3.5 mm terminal blocks accept up to +24 dBu, with rear panel attenuation controls for level matching. Speakers connect to eight 2-pin 7.62 mm detachable terminal blocks rated 20 A, taking up to 12 AWG wire. Levels can be adjusted and monitored remotely in the Crestron Avia Audio Tool software, or from a touch screen or mobile device once the amplifier is integrated with a Crestron control system.

When replacing a unit, check the model on the existing amplifier: the AMP-8150 supports 4/8 ohm and 70 V output on 100 to 120 V AC, while this AMPI-8150 supports 100 V output and runs on 220 to 240 V AC. Per-channel fault protection and output relays guard the speakers, and front panel LEDs and output meters show status. The fan-cooled chassis is 439 mm wide (483 mm with the included rack ears) and 374 mm deep.

Questions about the Crestron AMPI-8150

What is the Crestron AMPI-8150?

It is an eight-channel power amplifier from Crestron's AMP-8000 series, rated at 150 W per channel in a 1 RU rack-mountable chassis. This international model supports 4/8 ohm and 100 V outputs and runs on 220 to 240 V AC. It is built to work alongside Crestron's Avia digital signal processors.

What is the difference between the AMPI-8150 and the AMP-8150?

Crestron offers two versions. The AMP-8150 supports 4/8 ohm and 70 V output and runs on 100 to 120 V AC. The AMPI-8150, the international model on this page, supports 4/8 ohm and 100 V output and runs on 220 to 240 V AC. Both give 150 W per channel.

Can the AMPI-8150 bridge channels?

Yes. Adjacent pairs of channels (1 and 2, 3 and 4, 5 and 6, 7 and 8) can be configured for stereo or bridged operation, and each channel can also run in mono, independently of the others. A bridged pair gives 300 W into 8 ohms.

How is the amplifier controlled and monitored?

Levels can be adjusted and monitored remotely in the Crestron Avia Audio Tool software, or from a touch screen or mobile device once the amplifier is integrated with a Crestron control system over its 10/100 Ethernet port. Rear panel attenuation controls allow input level matching, and a front USB port is for setup only.

What protection does it have?

Every channel is protected individually: over-current protection guards against too heavy a speaker load or a shorted speaker line, and DC offset protection is built in. Output relays cut each speaker line if a fault occurs and while the amplifier starts up or shuts down, and front panel LEDs flag under-voltage, over-current and DC offset faults.

How much is the Crestron AMPI-8150?

Crestron asks its dealers to give the price of the AMPI-8150 directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.

Can 1Install supply, install and programme the AMPI-8150?

Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the AMPI-8150 on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.

Does the AMPI-8150 come with a warranty?

Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the AMPI-8150 develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.

Is the AMPI-8150 in stock?

We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Can I buy the AMPI-8150 without installation?

Yes. We supply Crestron to end users, with or without installation. If you are not sure it suits your system, send us the part numbers you already have and we will check.
