Crystal Motor for Arri 16-BL:

The TXM-25 gives basic crystal sync at low cost.  It is used where the original BL motor cannot be crystal controlled. (This motor is not recommended for students or rental, owing to the rather small and delicate nature of the speed switches etc.)

Nine (Eleven) Crystal Speeds

9.375, 12, 12.5, 15, 18.75, 24, 25, 30 and 37.5 FPS (frames per second). With the 24:50, 24:48 or 25:50 gear set you should be able to also run at 48 and 50 FPS. The 60 Hz HMI speeds are 12, 15, 24 and 30 FPS. For 50 Hz the HMI speeds are 12.5, 25 and (if available) 50 FPS.

Work With Any Gear Ratio
Made in three sub-models* to be used with the four original gear sets. All speeds within range will be correct with either 24:50, 24:48, 25:50 or 24:60 gears.  No gears? We make a 24:60 set for $100.

External Speed Control

An RJ-12 receptacle accepts the TCS Milliframe Controllers for .001 FPS speed increments over the range of 8 up to 42 or 50 FPS depending on the gear ratio. There is an output for the TMC2's footage counter. The Videoframe Controller can be used for getting just 23.976 and 29.970 FPS. Connecting the speed control requires removing the motor shroud and passing the RJ-12 cable through the removable window. The motor shroud can then be replaced, perhaps using a cutout cork or stopper to minimize noise leaking out of the opening. (Unplugging the cable again can be tricky, if you are using external speed control a lot you might want to cut off the latching button from the plug.)

Sync Alarm

A red light shows if correct speed is not maintained.

Other Information

The speed switches and sync alarm are all accessible through the removable window in the back of the motor shroud (formerly used for the reversing switch on the old original BL motor.)
The unit installs in place of the original motor. Connection is with just two wires that plug into the motor receptacle. If you are uncertain about the installation procedure, we will install it at no extra charge, with shipping at your expense and risk. This will enable us to precisely adjust the motor to suit your camera. Make sure the mirror shutter is in the vertical (non-viewing) position to minimize the chance of damage in transit.
If your camera has a fully functional "Universal" EMP or BLE motor, and intact wiring and undamaged Amphenol/Bendix 9-pin connector, you instead need to order the TXM-27.
The TXM-25 is priced at $795. *Please Specify Version: (Count the teeth on your gears. Or, just send us the camera and magazine and we will count the teeth, as part of the installation!)
TXM-25/24 for use with USA Universal Motor 24:50 gear set. (Has 24 tooth encoder disc.)
TXM-25/25 for use with European 25:50 and 24:48 gear set. (25 tooth disc.)
TXM-25/20 for use with USA Reversing Motor or Synchronous Motor 24:60 gear set. (20 tooth disc.)

24:60 Gear Set if required, $100.            Operating instructions can be previewed here.

Possible Accessories: Battery Belt or AC Power Supply (requires a different plug, or adapter pigtail, to fit the original Amphenol/Bendix receptacle.)
