Crestron AMP-X300 – X-Series 4-Channel 300W Modular Power Amplifier

Product Overview

The Crestron AMP-X300 is a professional-grade 4-channel Class D power amplifier in a half-rack 1RU form factor delivering up to 300W total output across configurable Lo-Z (4Ω/8Ω) and Hi-Z (70V/100V) operating modes. Four independent channels at 75W each in Lo-Z stereo can be reconfigured for 2×150W bridged, single-channel 300W bridged, or 70V/100V constant-voltage Hi-Z distributed speaker operation — providing multi-zone commercial audio and large-room speaker coverage from a single half-rack unit. ENERGY STAR certified with auto-standby, signal-sensing wake, and fanless convection cooling, the AMP-X300 gangs with other Crestron X-Series half-rack amplifiers in a single 1RU rack space using included hardware.

Product Description

Commercial multi-zone audio installations frequently require different amplifier configurations across zones — stereo speaker pairs in conference rooms, bridged mono in auditorium fill positions, and 70V/100V constant-voltage lines in corridor and lobby areas — that would traditionally require multiple separate amplifiers. The AMP-X300 consolidates these into a single half-rack unit through its configurable 4-channel architecture: two front-panel slide switches independently configure channel pairs 1+2 and 3+4 for stereo, summed mono, bridged Lo-Z, or Hi-Z constant-voltage operation, allowing completely different configurations on the same amplifier simultaneously. This means channel pair 1+2 can drive a stereo conference room speaker system at 75W per channel while channel pair 3+4 drives a 70V ceiling speaker zone at 150W from the same unit. Advanced Class D topology maximizes efficiency while minimizing heat, and the convection-cooled chassis supports high-density rack installation without ventilation clearances between ganged units. The included hardware set covers surface mount, freestanding, full-rack, and ganged half-rack mounting configurations — requiring no additional mounting accessories or shelves at installation.

Key Features

• 4-Channel, Up to 300W Total Configurable Output: Four independently driven channels at 75W each in Lo-Z stereo; independently reconfigurable to 2×150W bridged, 1×300W mono bridged, or 70V/100V Hi-Z — one amplifier handles stereo, mono high-power, and constant-voltage distributed speaker system requirements.
• Independent Channel Pair Configuration: Two slide switches configure channel pairs 1+2 and 3+4 independently — stereo, summed mono, or bridged Lo-Z; Hi-Z mode bridges both pairs for constant-voltage. Different configurations on each pair simultaneously possible.
• Half-Rack Gangable Form Factor: 1RU half-width chassis gangs two AMP-X300 units side-by-side in a single 1RU rack space using included hardware — providing 8 channels or up to 600W in one rack unit for high-density multi-zone commercial audio rack builds.
• ENERGY STAR Certified with Auto-Standby: Signal-sensing standby after 25 minutes of no signal; wakes in under 0.5 seconds on signal detection; “Always On” mode also selectable — meets ENERGY STAR requirements for commercial AV energy management.
• Balanced and Unbalanced Inputs on All Channels: Balanced via 3.5mm detachable terminal blocks and unbalanced via RCA connectors on each of the four channels; inputs sum for simultaneous balanced and unbalanced source connection.
• Fanless Convection Cooling: Passive convection cooling eliminates fan noise for conference room, boardroom, and quiet commercial AV environments where background amplifier fan noise is unacceptable.
• Screwdriver-Adjustable Per-Channel Gain: Independent gain trim on each of the four channels enables precise level matching across multi-zone commercial audio systems at commissioning without external line level processors.
• All Mounting Hardware Included: Surface mount flanges, adhesive feet, rack mount brackets, and ganging hardware all included — no additional mounting accessories required at installation regardless of deployment type.

Typical Applications

• Multi-zone commercial audio with four independently driven speaker zones from a single half-rack amplifier in conference room AV racks
• Large conference rooms and boardrooms requiring bridged mono or 2-channel high-power speaker amplification with separate fill zone amplification from one unit
• 70V/100V constant-voltage distributed ceiling speaker systems with up to 300W total zone capacity in commercial lobbies and corridors
• Training rooms and all-hands rooms with front speaker pair and ceiling fill speaker zone amplification from a single device
• Houses of worship with sanctuary, lobby, and monitor position audio zones driven from one half-rack amplifier
• High-density multi-zone commercial audio racks with ganged AMP-X300 pairs providing 8 channels per 1RU

Frequently Asked Questions

Can the two channel pairs be configured independently for different modes?
Yes — channel pair 1+2 and channel pair 3+4 each have their own configuration slide switch. One pair can be set to stereo Lo-Z while the other is set to bridged Lo-Z or Hi-Z simultaneously, enabling different operating modes per pair from the same unit.

How does the AMP-X300 gang with other amplifiers?
Two AMP-X300 units gang side-by-side in a single 1RU rack space using the included ganging hardware, providing 8 channels or up to 600W total in one rack unit. Surface mount, freestanding, and full 1RU rack single-unit mounting hardware is also included.

What is the maximum Hi-Z output in 70V mode?
In Hi-Z mode, both channel pairs are bridged and combined — delivering up to 300W into a single 70V or 100V constant-voltage speaker zone, or 150W each into two separate zones. Contact Creation Networks for speaker load calculation guidance.

Is the AMP-X300 compatible with Crestron 4-Series control for room automation?
The AMP-X300 provides a contact closure remote standby input compatible with Crestron relay outputs for room power-on/off automation. For programmatic volume control, pair with a Crestron DSP with IP-controlled output level. Contact Creation Networks for integrated audio system design.

Can the AMP-X300 replace multiple separate single-channel amplifiers?
Yes — four independently configurable channels can replace up to four separate single-channel amplifiers in a multi-zone commercial audio rack, reducing rack space, cabling, and power supply count. Contact Creation Networks for system consolidation design guidance.

What is the warranty on the Crestron AMP-X300?
Crestron provides a standard 3-year limited warranty. Contact Creation Networks for warranty service and extended support options.
