Audio Output Connector
A 1/8 inch TRS connector is available for monitoring two channels of audio,
selectable in channel pairs using the Control Panel application. Typically used
with a pair of headphones.
Audio Level Meter
The Audio Level Meter in the center of the front panel indicates the sum of
whatever sources are being played out to the HDMI and SDI embedded audio
video output; i.e. NLE timeline and mix of host system audio output (if applicable).
The meter's LEDs are colored to indicate the amount below 0dBfs when averaged
over a one millisecond time interval.

NOTE: These audio level meters are for guidance only. Third-party audio metering
should be employed when doing critical audio editing and mixing.
Audio Gain Control Knob
The front panel volume knob can be assigned one of two different functions,
via the AJA Control Room application. This encoder spins freely, without max/
min limits. The gain increases to max, and then returns to zero after a complete
rotation.
• The knob's default function is to simply adjust the audio level being sent to
the T-TAP Pro's front panel audio output connector (headphone jack). The
embedded audio being output by T-TAP Pro is always indicated on its front
panel VU meters, which in this situation will not be changed by your knob
adjustment.
• Alternatively, the knob can be assigned to adjust the level of the embedded
audio being sent out the T-TAP Pro's rear SDI and HDMI connectors. In this
situation the front panel VU meters will report your level changes. An example
of using this feature would be to trim the level of the embedded audio output
because it was increased after mixing in a computer originated audio source.
NOTE: Since the headphone output is derived from the master level, adjusting the
embedded audio levels will also affect the levels driven to the front panel analog
audio output.
Power Connection Status LED
This LED indicates the current connection status of your T-TAP Pro.
• OFF: No power detected
• AMBER SOLID: Power is on but Thunderbolt is not live (e.g. Thunderbolt ports
disabled in host, BIOS settings)
• AMBER BLINKING: Thunderbolt is awake but no PCIe connection to host (e.g.
device hasn’t been whitelisted by the Thunderbolt software running on host)
