Front Panel

The Vaddio MicVIEW is the microphone switching unit for use in an automated
camera positioning system or in a stand alone operation. The MicVIEW has twelve
microphone inputs with 24V phantom power and +5V status line outputs. Micro­phones one and two can disable the phantom power and switch between mic-level
and line-level inputs such as cordless, lapel microphones.

• Carefully remove the device and parts from the packing material.

• Set the unit on a flat, solid surface. Unpack and identifiy the following parts:

MICROPHONE CONNECTORS

(1) PWR – Power Connector.
(2) MICROPHONE LOGIC OUTPUT +5V – status line outputs for indicating which microphone is active.
(3) CONTROL – RS-232 Port for external control of the MicVIEW functions.
(4) LINK IN/OUT – Link Port for connecting multiple MicVIEW units for expanded functionality.
(5) AUDIO LINE OUTPUT – Analog line level output for connection to amplifier or codec for broadcast or
transmission of audio.
(6) MICROPHONES – Twelve 3-Pin connectors for connecting external microphones with 24V phantom
power.
(7) MUTE – Connecting these pins mutes microphones 2-12 and any linked MicVIEW systems.

1.) Connect the (+), (-), and (S)hield pins on microphone Inputs 1-12 to the respec-

tive microphones.

• Microphones 1 and 2 cam be switched to line-level or mic-level with or without

phantom power. Press the Input x Mic button on the front to toggle between mic­level and line-level, and press Input x Phantom Power to toggle phantom power
ON/OFF.

2.) Connect the (+), (-), and (S)heild pins on the Line Output to the line-level on a

codec or amplifier.

• To connect the line output to a phono

cable, connect (+) to the center pin on the
phone cable and the (S) on the MicVIEW
to the negative wire on the phone cable.

DO NOT connect (-) and (S) together as they may
damage the MicVIEW.

WARNING

3.) The MicVIEW units can be linked together by standard Straight-through 6-Pin

RJ-11 cables. The Link light will illuminate when the link is correctly established.

• If two MicVIEW units are to be used to-

gether, connect the Link OUT of the Mas­ter system to the Link IN of the slave uni
(see figure at right). Continue by connect-

4.) If the MicVIEW is to be used with an external system where it is necessary to

know which microphone is active such as the Vaddio ControlVIEW, connect the
Microphone Logic Outputs to the corresponding input connections on the external
device.

5.) Press the Push-To-Talk button to switch between Push-T o-Talk mode (light ON)

and Voice Activated mode (light OFF).

6.) Adjust the Gate thresholds to set the gating for optimum performance by turning

the screw terminal to the left or right to adjust sensitivity. For Push-To-Talk mode,
adjust the Low Gate threshold and for Voice-adtivated mode, adjust the High Gate
threshold.

7.) Adjust the Input Level adjustments to adjust the volume of each microphone.

8.) Adjust the 5-Band Graphic Equalizer for best sound quality for the application by

turning the control to the left or right.
OPERATION

• Voice Activated – Turn on all microphones. Turn OFF Push-To-Talk mode (light

OFF). adjust the Gate Threshold so the ambient noise does not cause a micro­phone to trigger. One configured for voice activated mode, there is no need for
user intervention. The loudest voice gets control.

• Push-To-Talk (PTT) – Set all microphones to Push-To-Talk (PTT). Turn ON PTT

mode on the MicVIEW (light ON). Adjust the threshold. In PTT mode, a user must
press the PTT button on the microphone and speak into the microphone. When the
user is finished speaking, the user must release the PTT button.

The system doesn’t rec­ognize a voice when
someone speaks in
Push-To-Talk mode.

Make sure the microphone is connected to the
MicVIEW and it is on.

Turn OFF the Push-To-Talk mode.
Check Threshold level. Turn the threshold to the

left to reduce sensitvity and to the right to increase
sensitivity.

The MicVIEW uses 24V phantom power. Make sure
the microphones can accept 24V phantom power.

If the microphone is Microphone 1 or Microphone
2, make sure the phantom power is turned ON and
the input is set to Microphone level.

Make sure the microphone is connected to the
MicVIEW and set to Push-To-Talk mode.

Verify the MicVIEW is in Push-To-Talk mode (light
should be ON).

Make sure the Push-To-Talk button is depressed
when speaking.

Check Threshold level. Turn the threshold to the

The MicVIEW uses 24V phantom power. Make sure
the microphones can accept 24V phantom power.

If the microphone is Microphone 1 or Microphone
2, make sure the phantom power is turned ON and
the input is set to Microphone level.

Check the Master output. Turn the master output
to the left to decrease volume, to the right to in­crease volume.

If a microphone is connected to input one or two,
check to see that the Mic level has been selected.

If a device with a line-level output is connected to
input one or two, check to see that Mic level has
been turned OFF.

Troubleshooting

Problem

Suggestion

The system doesn’t rec­ognize a voice when
someone speaks in
voice activated mode.

Input one works but the
rest do not.

Audio output quality is
poor, but volume is
good.

Link does not appear
to work.

Each input has an individual gain. Adjust the Input
level adjustment to the left to reduce the gain or to
the right on increase the gain of a specific input.

Make sure the Local Student mute is not enabled.

Adjust the 5-Band equalizer to improve sound
quality.

Make sure to use 6-Pin, RJ-11 cables to connect
the MicVIEW Link. Although the connectors look
like a telephone cord, the system requires six (6)
wires to function.

The Link uses a Master-Slave setup. The
MicVIEWs in the Link must be configured as Slaves
and the main unit must be configured as a Master.

Connect the Link OUT on the secondary MicVIEW
to the Link IN on the primary MicVIEW.
