Crestron AMP-2100-1002x100W 100V Constant Voltage Power Amplifier Fanless Wty

Crestron AMP-2100-100 Dual-Channel 100V Power Amplifier

A half-width commercial power amplifier built for 100V constant-voltage distributed speaker systems, delivering two independent 100-watt channels with silent, fanless operation. Every unit is certified refurbished, fully tested in Melbourne and backed by a 12-month warranty from Reboot IT.

Key Benefits

• Dual 100W channels at 100V. Two independent 100-watt amplifier channels are built for 100V constant-voltage (Hi-Z) speaker lines, the standard used in commercial ceiling and wall-speaker installations.
• Fanless, silent operation. Convection cooling means there is no fan noise, so the AMP-2100-100 can sit in a boardroom credenza, a classroom AV rack or a reception cabinet without adding background hum.
• Space-saving half-width 1RU design. The amplifier is a half-width 1U chassis that can be rack mounted or surface mounted, and is gangable alongside a second half-width unit to fill a single rack space.
• Automatic standby power saving. Built-in circuitry drops the amplifier into low-power standby after 25 minutes without an input signal, cutting power draw during idle periods and waking automatically when audio resumes.
• Purpose-built for commercial Hi-Z audio. Designed specifically for 100V constant-voltage systems, it suits multi-zone paging, background music and distributed ceiling-speaker installations rather than home hi-fi setups.
• Certified refurbished and warranty backed. Every unit is tested by our Melbourne technicians and comes with a 12-month warranty from Reboot IT, so you can add reliable amplification to an existing 100V system with confidence.

Performance in Use

In a boardroom or meeting-room fitout, the AMP-2100-100 typically sits inside an AV rack feeding a set of ceiling speakers used for background music, video-conference audio or paging announcements. Because the two channels are rated for 100V constant-voltage distribution, the same amplifier can drive a run of transformer-tapped ceiling speakers spread around the room without the wiring complexity of a low-impedance system. The fanless, convection-cooled chassis runs for hours during a full day of meetings without adding audible hum to the room, and the half-width 1RU form factor tucks neatly alongside switchers, DSPs and control processors in a compact credenza rack.

Schools and training rooms often need to cover several classrooms or common areas from a central plant room, and the AMP-2100-100's two channels make it straightforward to add coverage zone by zone. The gangable half-width design means a second unit can sit in the same single rack space to add more channels as a campus grows, and the automatic 25-minute no-signal standby helps keep power draw down through evenings, weekends and school holidays when the paging and background-music system sits idle. Because it is a 100V constant-voltage amplifier, it pairs directly with the transformer-tapped ceiling and wall speakers already fitted in most education and office buildings.

For AV integrators managing an existing 100V audio estate, the AMP-2100-100 is a straightforward way to add channels or swap out a unit in a venue, retail fitout or hospitality space that already runs 100V distributed speakers. As a discontinued Crestron model it is best treated as a like-for-like amplifier for an existing installation rather than an active platform, so it is supplied as a standalone amplifier without ongoing manufacturer firmware or software updates. Fitted into a live estate it behaves exactly as the original unit did — feeding two channels of 100W into the building's constant-voltage speaker lines — making it a practical option for expanding coverage or replacing a faulty channel without redesigning the whole system.

Physically, the AMP-2100-100 is designed to disappear into existing AV infrastructure. The half-width chassis mounts using standard rack ears or sits on a shelf inside a cabinet, and its two independent channels can be wired separately to cover two different zones or combined to add depth to a single larger zone. Because it is a 100V constant-voltage design, the cable run to each speaker only needs a single pair of wires regardless of how many speakers share that channel, which keeps installation simple compared with low-impedance systems that need careful load matching. For an integrator maintaining several 100V-equipped sites, having a dependable spare or replacement channel on hand — with the reassurance of a 12-month warranty from Reboot IT — reduces the risk of a background-music or paging system going silent.

Frequently Asked Questions

Is this amplifier compatible with standard 4 or 8 ohm speakers?

No. The AMP-2100-100 is a 100V constant-voltage amplifier designed for transformer-tapped distributed speaker systems, not standard 4 or 8 ohm hi-fi or home theatre speakers.

What is a 100V constant-voltage speaker system?

It's the standard method used in commercial background music and paging installations, where speakers are wired with a transformer tap so several speakers can share one amplifier channel across long cable runs, rather than the low-impedance wiring used in home hi-fi systems.

Is the amplifier fanless?

Yes. It uses convection cooling with no internal fan, so it runs silently in boardrooms, classrooms and other spaces where background noise needs to stay low.

Can I rack mount it?

Yes. It's a half-width 1RU chassis that can be rack mounted or surface mounted, and it's gangable alongside a second half-width unit to share a single rack space.

Does it include ongoing Crestron support or firmware updates?

No. This is a discontinued Crestron model, so it's supplied as a standalone amplifier for expanding or replacing a unit in an existing 100V system, without ongoing manufacturer firmware updates or support.

What happens if there's no audio signal for a while?

The amplifier automatically drops into a low-power standby mode after 25 minutes without an input signal, and wakes again as soon as audio resumes.
