9:DC input - This jack will accept a DC input voltage of 6 - 13 volts (inner connection [tip] positive, outer connection [sleeve] ground) from your video camera, if available. Connect the optional Samson AC300R adapter here to charge a rechargeable 9-volt Ni-Cad battery.

10:Unbalanced output* - Use this unbalanced (1K Ohm max.) 1/8" (3.5 mm) mini-phone jack when connecting the UM1 to consumer (-10) audio equipment. Wiring is as follows: tip hot, sleeve ground. If your video camera has stereo audio inputs, you’ll need to use a Y-adapter that has a 1/8" (3.5 mm) mini-phone plug at one end and dual male RCA-type plugs at the other end.

11:Audio Output Level switch - Sets the audio output level of both the balanced and unbalanced outputs (see #10 above and #14 below) to -30 dBm (mic level), -20 dBm, or -10 dBm (line level). See the “Setting Up and Using the UM1 System” section on page 8 in this manual for more information.

		E	D	O			headphones output (see #13 below).

							stereo headphone to this standard 1/8" (3.5
							mm) mini-phone jack in order to monitor the

signal being output by the UM1. We recommend the use of 30 ohm headphones. The level of the headphone signal can be set by adjusting the Level control (see #12 above). Maximum output is 240 mW @ 30 ohms).

14:Balanced output* - Use this electronically balanced low impedance (600 Ohm)

mini-XLR jack when connecting the UM1 to professional (+4) audio equipment. Pin wiring is as follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).

15:Meter switch - This three-position switch determines the function of the front-panel UM1 meter (see page #2 on previous page). In the left “RF” position, the meter indicates the strength of the incoming RF signal. In the center “BATTERY” position, the meter indicates relative battery power, showing whether the installed battery is at low (red), mid (yellow) or high (green) strength. (Note: When the red “low” indicator lights, performance is degraded and the battery needs to be replaced). In the right “OFF” position, the meter is disabled altogether, thus conserving battery power.

*If required, both the unbalanced and balanced outputs can be used simultaneously.
