Look no further than the Crown Audio DCI 4 300N , a 300W DriveCore Install 4 channel BLU Link network amplifier with advanced features and flexibility.

System integrators working on challenging 21st century installed sound applications require equipment that is versatile, compact, and highly efficient. Look no further than the Crown Audio DCI 4|300N , a 300W DriveCore Install 4-channel BLU Link network amplifier with advanced features and flexibility. The amplifier provides analog and digital inputs, network monitoring and control, programmable General Purpose Input/Output (GPIO) ports, and on-board Digital Signal Processing (DSP). The amplifier also meets EN 54-16 compliance for life safety systems to serve the needs of hospitality, large venues, and other markets.

The 2 RU 4/300N can produce up to 300W of output per channel at 2, 4, 8 or 16 ohms or 70 or 100 Vrms. It is compatible with Harman's BLU Link digital audio transport and accepts digital inputs via its rear-panel RJ-45 connectors. This digital control allows for networked monitoring, recallable presets, and the setup of secondary inputs that engage if the primary inputs fail. The built-in DSP capabilities include limiting, input/output EQs, delay, and a matrix mixer.

Each channel pair can be bridged for powering higher power applications such as a subwoofer. The 4|300N also has channel-independent high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 4 channels additionally features independent attenuators with a range from 0 to -80 dB.

The front panel of the 4|300N provides a series of system indicators, including level and signal, ready, clip, thermal, and fault alerts for quick visual monitoring of the system. The unit can be integrated into a control system for powering on and off as well as engaging its sleep mode for saving energy when not in use.

Network Monitoring & Control
Monitoring, control, and audio manipulation are provided with the HiQnet protocol that's over standard TCP/IP. Remotely see how all networked DCi amplifiers are performing and control them as needed. In addition, this allows Audio Architect software and the Powered by Crown app to work with DCi amplifiers.
Programmable General Purpose Input/Output Ports
GPIO ports can be configured in many different ways, such as volume controls, recall presets, or to report errors to a master computer.
DSP
DSP includes LevelMAX limiters, input/output EQ, delay, matrix mixer, and speaker line monitoring.
Direct Drive Constant Voltage
You can use smaller-gauge wiring to drive the speakers using either 70/100 Vrms. With no need for a step-up transformer at the output, the DCi produces audio more efficiently.
Channel-Independent Hi-Z/Low-Z Selection
Drive either one to four speakers in low-Z mode, or literally hundreds of speakers in hi-Z mode (70 Vrms or 100 Vrms). This means design flexibility since DCi powers all loads on a channel-by-channel basis.
Bridgeable Channel Pairs
The DriveCore Install Series channels are bridgeable, even in 100 Vrms mode, allowing them to be used to for higher-power applications like subwoofers.
Remote On/Off Interface
The amplifier can be integrated into a control system for remote on/off control.
Efficient Cooling Design
Efficient internal cooling fans provide airflow to the most heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise.
Auto Standby
The amplifier automatically goes into sleep mode after 30 minutes of no input signal.
TLC Protection
The amp has built-in protection from excessive heat by applying gain reduction when necessary.
Advanced Protection Circuits
Amplifier and loads are protected against shorted outputs, DC, mismatched loads, overheating, over- or under-voltage, and high-frequency overload.

Surprisingly comfortable and stylish wrist rest!
Color: Walnut Wood, Size: Large
This wrist rest is the perfect compliment to my desk set up. I was hesitant about buying a wood product like this, but I’ve been pleasantly surprised how comfortable and smooth it is during extended use. For the price, it feels like a premium product, and I love that it stays put with the rubber feet. The size is perfect for a full-size keyboard, with just the right thickness to keep your wrist and palms comfortable. If you’re looking for an elevated way to decorate your desk while protecting your wrist, this is a great choice.

Great wrist rest with a modern look!
Color: Walnut Wood, Size: Medium, Color: Walnut Wood, Size: Medium
This is a great looking addition to my desk. It’s a just the right length to fit my keyboard and I love the walnut coloring! It’s real wood and has nice rubber feet on the bottom to keep it from moving around. The angle is nice for my wrists and it’s easy to clean with just a damp cloth. If I ever wear this one out (which I doubt) I’d buy another!

Super comfortable - much better than memory foam wrist rests!
Color: Walnut Wood, Size: Large, Color: Walnut Wood, Size: Large
Get this wrist rest - you won't be disappointed. Had ergonomic keyboards and have tried memory foam rest in the past and this is much better. Smooth wood, perfect height and very supportive to keep wrists in neutral position when typing. Got the 17.3" and like that there's ample room to not feel squashed, but probably could have done with the medium length. Great angle for my mechanical keyboard. Love it!

What an excellent wrist rest! Except for this one thing....
Color: Walnut Wood, Size: Large
This is a solid piece of wood with great quality. Fantastic large rubber grips on the bottom (left and right sides only). Pro: I use it for editing and gaming. And though I thought the wood might be a bad choice in the long run, it turns out it's pretty nice. Not as comfortable as a gel rest but I knew what I was getting when I ordered it. I buy things for function AND aesthetics. I love how this looks. The uniqueness is really something. I got the natural one instead of the black so that the grains and lines can be easily seen. Con: Unfortunately, after almost 2 months, the wood has warped some. Not enough to effect my typing but, enough that I notice it. The warp is the kind where the opposite angled corners go up and down. While the other 2 corners are fine. In my case, the top left and bottom right, when pressed independently, rock the wrist rest. The top right and bottom left stay grounded. This is why I took a star off. Because there's no way this should be happening. So, looks and quality are up there. The rubber grips are solid. Why it's warping is puzzling to me. NO liquid wasted on it. Or, extreme temperature changes have happened. I've made sure the rubber grips. And that the surface the rest sits on (a glass mouse scrolling top by Superglide) is clean. Yet, I get this slight rocking. It bugs me this all happened right after the return window closed. I would've simply exchanged it. I love it too much. I mean, this is, again, a SOLID piece of wood. Maybe this won't happen for everyone. I mean, it's wood. Eh I would still recommended this regardless.

Fantastic Product
Color: Walnut Wood, Size: Small
This is very nice! I type all day for my job and this made a big difference. It's very comfortable and supportive. Im allergic to latex rubber, which is in most gel options. It's really nice to have a safe, effective alternative
