Guided Tour - VM1
9: DC input - This jack will accept a DC
input voltage of 11 - 14 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 1/8" (3.5 mm) mini-phone jack to connect
the VM1 to your 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 the unbalanced output
(see #10 above) to -30 dBv (mic level), -20 dBv, or -10 dBv (line level). See the “Setting
Up and Using the VM1 System” section on page 8 in this manual for more information.
12: Level control - This knob sets the level of the audio signal being sent to the
headphones output (see #13 below).
13: Headphones output - Connect a
stereo headphone to this standard 1/8"
(3.5 mm) mini-phone jack in order to monitor
the signal being output by the VM1.
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
200 mW @ 30 ohms.
14: Meter switch - This three-position switch determines the function of the front-panel
VM1 meter (see page #2 on previous page). In the left “BATTERY” position, the meter
indicates relative battery power, showing whether the installed battery is at low (red), mid
(yellow) or high (green) strength. When all three LEDs are lit, the battery is at maximum
strength. When only the red “low” indicator lights, performance is degraded and the battery
needs to be replaced. In the center “RF” position, the meter indicates the strength of the
incoming RF signal. In the right “OFF” position, the meter is disabled altogether, thus
conserving battery power.
