The Black Box AC556A-R2 Multimedia Extender Kitby Black Box, comprised of a local transmitter unit and a remote receiver unit, allows you to broadcast VGA computer video and stereo audio up to 500' from the host computer over a CATx cable (CAT5 or higher). The video resolution goes up to 1024 x 768. The extender supports 2 local and 2 remote VGA monitors and features audio outputs for plugging in, for instance, a pair of speakers next to each of the 4 monitors. The AC556A-R2 takes the left and right channels of a stereo signal input on the local unit, sends them to the audio outputs, where they are "mixed" together to form a mono signal before transmitting to the remote unit via CATx.

An LED lights on the local unit when the extender detects a VGA input signal and on the remote unit when it properly decodes VGA signals for the two VGA ports. The remote unit features an equalization (gain) selector switch. To fine-tune the images, adjust this switch to match the length of the CATx cable between the units. A 2kV avalanche diode provides electrostatic discharge (ESD) protection. Typical digital signage applications of this extender include exhibits, retail, trade shows, and airports.

Q: 7. What happens if I connect to all three input possibilities at the same time; 1/4" TS, RCA, and 3.5mm TRS. Will it prioritize one over the others and output from only one source, or will it blend all three sources before outputting via the XLR outputs?

A: The direct box is intended to be used with one input source only. If three sources are connected to three different inputs they would be blended together into one signal which may have issues with phasing.

Q: 8. It was necessary to remove this grip due to a return of my RX100 M5 due to a defect. I will be receiving a replacement RX100 M5. Does anyone know what type adhesive tape I can use when I refit my current grip on the replacement camera?

Q: 9. Does this sound better than Kopul PDI-40? Or are the electronics inside the same? This model has more inputs and outputs, but if I only need one, will get the same quality using the model# PDI-40?

A: The SDI-PPC and PDI-40 are designed for use with different equipment, so the best option depends on the device you are going to be using and the application it is being used for. The SDI-PPC is a stereo direct box with stereo input and output. It has a stereo 3.5mm input for smartphones, tablets, and compatible media players, a pair of RCA jacks for turntables, A/V connections, computer soundcards, and a pair of 1/4" TS inputs for connecting instruments like guitar, bass, and keyboards to a mixer. Two XLR outputs are provided for left and right stereo signal or for splitting an instrument's output to route it to two destinations, like an amplifier and a mixer. A -15 dB pad is included for attenuation and a ground lift switch helps to eliminate hum. The PDI-40 has a single XLR input and single XLR output for connecting a microphone or an instrument like guitar, bass or keyboards to a mixer. It has a switchable -20 or -40 dB pad and ground lift switch.
