The lightweight nXp1.5 4-Channel Multi-Mode Network Power Amplifier from Ashly features programmable output on each channel selectable via rear panel DIP switches with swept load impedance monitoring. Audio is processed via the 32-bit SHARC DSP at 48 or 96 kHz sample rates and a built-in signal generator is provided for test tone and noise-masking.

The nXp1.5 amplifier comes pre-installed with CobraNet network audio module and features aux preamp outputs. Ethernet control is supported via the free Protea NE software (downloadable from Ashly's website) and serial data control is possible via Ashly programmable remotes or third party controllers (available separately). The Protea DSP (Digital Signal Processing) software is included for dynamics, gain, equalization, matrix mixer, crossover, delay, and metering.

The amplifier is suitable for live sound and fixed installation sound systems at performance venues, stadiums, arenas, convention centers as well as schools, store fronts, and places of worship.

Related Questions and Answers

Q: 1. Is this compatible with the FX9 and if so, will it interface with the Ch 3&4 manual level controls on the camera?

A: The SMAD-P3D does work with the FX9 and interfaces with Channels 1 and 2. Levels are not adjustable using the internal controls on the camera.

Q: 2. Is there a connection for my rooftop FM antenna?

A: Yes this model has a 75 ohm antenna port on the back.

Q: 3. Does this ONLY work with dual channel receivers? I would like option to upgrade receivers with same she adapter in the future.

A: Yea, turns out you have to buy it, then find the answer buried in the tiny instruction manual . B&H: This kind of info needs to be in the description!! More $ to UPS.

Q: 4. Will this work with a URX-P03?

A: The SMAD-P3D cannot be used with the URX-P03 nor the URX-P40. The Sony SMAD-P5 is directly compatible with the URX-P03.

Q: 5. The Sony SMADP3D was listed as a recommended adapter for the PMW-300K1. I bought both and have realized the PMW-300K1 doesn't have the necessary MI shoe. Is there an additional adapter sold to make this work with the PMW300?

A: Unfortunately, the recommendation may have been an error. You are correct in that the Sony PMW-300K1 does not have an MI shoe. There is no adapter available at this moment that will allow you to integrate the Sony SMADP3D with the camera.

Q: 6. Does this work with the A7s iii?

A: Yes it will , Sony has the same Multi-Interface Shoe on all Mirrorless cameras

Q: 7. I have a Sony HDR-SR10, which lacks a 3.5mm external mic input, or any sort of external mic input. It has the HSI. Will this adapter allow for the camera to use the audio signal from a receiver via the HSI, since there is no other mic input on the HDR-SR10? If so, I can look into purchasing this adapter.

A: The SMAD-P3D is compatible with select cameras that feature Sony's Multi-Interface shoe. Unfortunately not compatible with the HDR-SR10.

Q: 8. Will this work on the a6300 using the dual channel wireless receiver?

A: The Sony SMADP3D Multi-Interface Shoe Adapter is compatible with the Sony a6300. User may connect the Sony URX-P03D 2-Channel Portable Receiver to the a6300 using this multi-interface shoe adapter.

Q: 9. Can I get 4 audio channels, like the XLR-K3M can do? I am using the SAMD P3D on A7siii. I can only get one stereo channel to the camera. When I try to set the camera menu to audio hot shoe settings it says my audio device needs to be switch to digital. I cannot find that setting. It worked on the XLR-K3M Camera firmware updated Please advise

A: No, this adapter provides two channels (left and right) of audio to the a7SIII when using a Sony URX-P03D dual-channel wireless receiver. The audio signal sent to the camera is analog, not digital. The adapter enables a wireless connection to the camera's mic input using the Multi-Interface Shoe.

Q: 10. I am shooting with the A7SIII and have been using the UTX-P03D. When I use the dual channel SMAD Unit, the ability to control audio levels in camera is suddenly disabled. Also the in the menu the (MI Shoe Audio Set) option is grayed out, not allowing me to control my levels anymore. Because of this I've been using the 2 channel Sony provided 3.5mm jack. Am I missing something, or does this SMAD unit only provide auto gain with no ability to control audio levels?

A: Awaiting a Call-Back from Sony on this, to confirm compatibility/usability with the A7s iii. One "theory" is that the A7siii is a "consumer" product and may not be (fully?) compatible. The Sony URX-P03D wireless receiver is to used with interface Sony SMAD-P5 Digital MI Shoe Adapter for UWP-D Series. ( https://www.bhphotovideo.com/c/product/1484185-REG/sony_smadp5_digital_mi_shoe.html). This is stated as applicable to SELECT Sony cameras (the A7s iii is not listed-see below): Key Features For UWP-D Series URX-P40 Receiver For Camcorders/Cameras with MI Shoe Digital Audio and Data Connection Switchable to Analog Connection Cable-Free Setup Show More The compact Sony SMAD-P5 is a digital Multi Interface (MI) Shoe adapter that allows you to mount the UWP-D Series URX-P40 receiver on select Sony camcorders and cameras equipped with the MI shoe architecture. The adapter eliminates the need for connecting cables, speeding your setup in the field. More Details The adapter also offers seamless integration with the Sony a7R IV and A9 II mirrorless cameras, the PXW-Z280/PXW-Z190 XDCAM camcorders, and the PXW-FX9 camera
