Ultra Precision Servo Matching System & Power Distribution System
JR's MatchBox lets you synchronize the neutrals, endpoints and reversing of up to 4 servos from a single receiver channel, power them with their own dedicated battery pack and cut your setup time to mere minutes.
Until digital servos came along, driving a single control surface with 2 or more servos wasn't all that difficult. If they fought each other a tiny bit, it wasn't the end of the world.
But when ganged digital servos aren't perfectly matched – or if horn geometry is slightly off – look out. Current drain can soar and surfaces strain as each servo battles to hold its position.
Enter, the MatchBox. Besides offering convenient servo matching, MatchBoxes can reduce the need to multi-channel mixing, prevent voltage drops to the receiver, and even eliminate the use of second receivers as nothing more than expensive bus bars. Which all adds up to a list of benefits programmable servos alone simply can't deliver.

The various functions of the MatchBox are accessible through the rotary dial as follows:
0: On. In this position, all settings remain stored. The INCR+ and DECR- buttons are not active. The MatchBox should always be kept in this position for normal operation.
1-4: In these positions, servo Neutral and End Point Adjustments (EPA) can be accessed and adjusted for each servo by using a combination of transmitter stick positions and the INCR+ and DECR- buttons.
5-8: In these positions, Servo Reversing can be accessed and adjusted for each servo by using a combination of transmitter stick position (neutral), and the INCR+ and DECR- buttons.
9: In this position, the values of the MatchBox can be returned to the factory default settings.
The Rotary Dial is coordinated to the servos as follows:
1/5: This is the port for the 1st servo. Position 1 adjusts neutral and End Point Adjustments (EPA). Position 5 adjusts the servo reversing for this servo.
2/6: This is the port for the 2nd servo. Position 2 adjusts neutral and End Point Adjustment. Position 6 adjusts the servo reversing for this servo.
3/7: This is the port for the 3rd servo. Position 3 adjusts the neutral and End Point Adjustments (EPA). Position 7 adjusts the servo reversing for this servo.
4/8: This is the port for the 4th servo. Position 4 adjusts the neutral and End Point Adjustments (EPA). Position 8 adjusts the servo reversing for this servo.
To RX: Connect to the appropriate channel of the receiver using the included Male/Male servo lead. A servo extension of up to 12" can be used if needed between the receiver and the MatchBox.
Aux Battery: Connect the included jumper connector if the servos will be powered by the current receiver battery pack. If a separate auxiliary battery pack and switch harness are to be used, connect these items to this port (optional).
1/5: Connect the first 1st to this port
2/6: Connect the 2nd servo to this port
3/7: Connect the 3rd servo to this port (optional)
4/8: Connect the 4th servo to this port (optional)
Note: The MatchBox will not function without the use of either the jumper connector or an auxiliary battery pack.
