The S-HOL-TCB01 is the official factory spare part number (SKU) for the Hollyland DB25 Male to DB25 Male Tally Cable.

Designed as the flagship connection cable for the Hollyland Wireless Tally System, this part functions as a direct 1:1 straight-through interface. It bridges heavy-duty live production switchers or main tally breakout matrices directly into the rear parallel control input of the master Hollyland Wireless Tally Station box.

Core Hardware Architecture

  • True 1-to-1 Parallel Pinout Map: The internal multi-conductor wiring is mapped identically across both ends (Pin 1 to Pin 1, Pin 2 to Pin 2, etc.). This ensures that low-voltage dry contact closures or tally voltage loops triggered on your video mixer perfectly match the internal channel lanes of the Hollyland system without any signal flipping.

  • Dual-End Male Form Factor: Both ends are built with standard-density DB25 Male connectors (2 rows of pins). This dual-male layout connects female output ports on production equipment straight to the female input port on the Hollyland transmitter hub, completely bypassing the need for an intermediate patch panel or gender changer.

  • Heavy-Duty Shielding Construction: Because it handles up to 25 separate low-voltage lines, the internal wire cores are wrapped inside a high-density, anti-interference foil layer. This shield protects your analog signaling lanes from crosstalk or false tally triggers caused by close contact with high-power equipment, studio lighting lines, or video server racks.

When to Order the S-HOL-TCB01 Spare

Keep this specific part number on hand if you are deploying any of the following live broadcast environments:

  1. Large Multi-Camera Setups: Since this cable uses all 25 parallel pins, it carries the highest density of separate Program (Red) and Preview (Green) cue signals simultaneously over a single cable run.

  2. Sony / Ross Video Switcher Deployments: Many traditional enterprise broadcast desks utilize a native female DB25 parallel interface for their external tally logic boards, making the S-HOL-TCB01 a clean plug-and-play fit.

  3. Control Room Rack Integration: At 1.5 meters (4.92 ft) long, this cable provides the perfect amount of slack to route neatly through cable management arms from a slide-out equipment tray over to your main engineering rack without creating messy, tangled wire webs behind your tech deck.

Denon avr ir remote port works great with sewell products
I bought a new entertainment center with glass doors and wasn't getting good signal range with the door closed. Plus i couldnt get a good of line site, since this cabinet was shorter than the orginal, and the location for my avr was further to the left than before and now my line of sight to the receiver was blocked from other parts of the room due to high couch back. I tried a couple different cheap $10 devices that used stick on transmitters/receiver buttons but they were clumsy and didn't provide me a total solution for my room layout. Works fantastic with a denon x1800 receiver (and many other models). It works directly with the denon's ir remote port in the back of the avr port. The solution is actually quite simple. Plug a stereo 3.5 mm male to male plug in the denon ir port in the back of the avr and and the other end to the orange emitter box(puck). The pics are about the size of an oreo double stuff cookie Tuck the orange box/puck away whereever and plug the power in. The box doesn't need to seen or be pointed towards anything. It's location is only limited by the length of your stereo cable and access to AC power Put the blue box puck anywhere in the room where you have general line of sight to it from where you will be using your remote, and plug power in. In my case, its sitting on top of one of my tower speakers. From there it clears the back of the couch and can see from the family room, eat-in kitchen area, and the kitchen beyond. Done. I didn't need or use any of the included emitter or transmitter cables, though if you dont have a denon, or other brand avr with an ir port to plug into , or also want to hide the blue puck ( in which case attach the included sensor cable), you'll need them. But for denon users with an ir port, you just use the two pucks and their usb power adapters. Simple.

Worked good then died at six months (Updated)
Worked good for a couple of months, then started to develop a lag between when you pressed a button on the remote, and when the TV would respond. If I moved the speaker blocking the TV’s IR receiver, and pointed the remote at it, it worked perfectly. Add the IR blaster back in and the delay returns. The delay kept getting longer and longer, sometimes 5 to 10 seconds. Then it just died. Would not pass any IR signals, even though the receiver and emitter both had power. Tried rebooting, changing communication channels to no avail. Out of Amazon return window. Manufacturer wants you do go through a troubleshooting process for warranty that is too complicated and time consuming. Customer Service Rep at Sewell send me a warranty replacement.

Nice Product and Customer Service
I ordered this BlastIR Wireless Pro IR Repeater from Sewell to replace a wired version of an IR repeater from another company. We have moved our TV on to a wall location and are in the process of hiding all the wiring out of sight behind walls and/or in a cabinet. We still have some wires to go, but this product has enabled us to eliminate the IR wiring all together. It's a real improvement in both looks and performance over the cheaper, wired version we originally tried. The BlasterIR's Receiver is the component that faces the room and receives the IR signal from our remote controls. It's small enough to fit in the space between our sound bar and the bottom of the TV. It's range is great for our room size (about 22' long and 18' wide) and picks up the remotes signal from a side angle that's almost parallel to the TV itself. The receiver is powered through one of the USB ports integrated into the TV (although the device itself supports either a USB or regular plug-in option). I haven't used them yet but Sewell appears to have provided a few options to help with affixing the IR devices in their final positions including some adhesive pads and a magnetic pad option as well. I'm still playing around with the permanent placement of the IR Blaster Emitter. It sits inside a closed cabinet and faces the concealed cable box receiver, router and DVR components. It retransmits the various IR signals it receives from the IR receiver by blasting that signal to anything it faces. I just placed it in the cabinet about 5" away from the devices I wanted to control, plugged it in and it worked with no other set up. So far the BlastIR is working seamlessly and with much better function response time than the cheaper IR version we'd tried at first. The lag time between when a button is pressed on the remote control and the action taking place on the device I'm communicating with is minimal. The emitter itself is plugged into an outlet on a surge protector powering the other in-cabinet devices, although it too could be powered via the provided USB connection if desired. As a note, we did experience a shipping issue during our ordering process. The order it self was processed quickly and shipped in a timely manner. However, there was an issue with our actual receipt of the product and the USPS who reported it delivered to our mailbox when in fact it had not been. Regardless, we reached out to Sewell directly and they quickly resolved the issue for us with no problems and in a timely manner. I would recommend both this IR Blaster Pro product as well as Sewell as a trusted company itself.

Does NOT Transmit Through Walls
Quick and easy setup! Works great within the room. However, will not work effectively between walls (i.e. - AV closet to living room).

Works perfectly - great product
My MBR TV set-up incorporates a cable box set up in a closet about 50 feet from the TV (hung over a fireplace). When it was set up the A/V used a wired infra-red set up that was wired thru the walls, under the floor, into the closet. Unfortunately some mice nibbled on the wiring and it does not work. I have tried everything including the Next Generation extender (over the years bought 6 of them for different TV's) and most recently the Startech. The Next Generation have not been updated in years and over time completely lose their ability to operate. No customer service at all; emails go into a black hole. I had high hopes for the Startech. Easy to set up and worked out of the box. The problem is the lag time. I could live with it when watching live TV, but it was totally impossible when it came to playing back programs from the DVR (which is cloud based). I was losing hope until I tried the Sewell Blaster. Took me less then 5 minutes to set up and it worked instantly. Little or no lag to speak of and I couldn't be happier. NB. Speaking of Sewell, the absolutely BEST way to control your HDMI based TV is the Sewell Direct SW-30062 Dual Band InjectIR sold by Amazon for $55. This is truly plug 'n play and operates with absolutely no lag. Bought 2 of these to operate TV's in my apartment where I had to hide boxes in closets. Well made, great instructions (coordinated with the devices) and I just love this product. I bought mine direct from Sewell ) same price) because I couldn't find them on Amazon when I needed them, but they have a great return policy and I'm told great C/S. If you can't use these then go for the Blaster.
