6 T-Desk Reference Manual
Proles
T-Desk allows you to save BaseStaon and BeltStaon sengs as “proles”. This is useful if the system is used in mulple
event applicaons and oers a quick and easy soluon to changing sengs. This sub-tab allows you to load previously saved
proles for either the BaseStaon or the BeltStaon(s) or save current BaseStaon or BeltStaon sengs as proles. Note: Using
the “All BeltStaons” loader will result in the BeltStaons all having the same sengs conguraon.
Wired Intercom Levels
The Wired Intercom Levels sub-tab allows you to acvate either 2-Wire or 4-Wire mode, and adjust the incoming and outgoing
audio levels on any of the intercom channels (A-D). The audio levels are measured in decibels (dB). To acvate a channel,
simply click the channel buon (A-D). Once the channel is acvated you can adjust the levels using the slider bar(s). To adjust,
use your mouse to click on the slider you want to change and drag it to the new posion (or use keyboard arrow keys). An
acve channel will appear in green and deacvated channels are grayed out. Note: A single intercom channel cannot be acvated in both
2-Wire and 4-Wire mode at the same me.
y Master Mode (Set Base as Master) - this mode is available when two or more BaseStaons are connected for 2-Wire
operaon, while slide switches (on BaseStaon) are set to ClearCom mode, and an external 2-Wire intercom system is not
connected. Master Mode will provide power for audio that a connected external 2-Wire intercom system would normally
provide. Master Mode is only available when the BaseStaon slide switches are set to ClearCom; a green Master Mode
light will come on in T-Desk when enabled. When unavailable (in RTS or Balanced (BAL) mode), the buon will be disabled
and grayed out.
y Null Two-Wire Hybrid - this buon iniates “nulling” on channels that are connected to a 2-Wire intercom system. Before
nulling, all talk buons (mics) must be o on all Tempest BeltStaons and all 2-Wire intercom devices to insure accurate
results. All 2-Wire intercom interfaces experience echo due to inherent ineciencies in the 2-Wire hybrid circuitry. When
the circuit is nulled, a tone is generated, the echo is monitored, and Tempest’s internal circuitry automacally adjusts to
minimize the echo. Any connecon made through 2-Wire intercom connecons requires nulling. For more informaon
on nulling refer to the Tempest2400 Wireless Reference Manual for more about nulling the system. Note: The nulling process will
interfere with normal communicaon, therefore, it should be done prior to use and not during.
To select the “type” of 2-Wire intercom system, use the slide switch(es) on the front of the Tempest BaseStaon labeled CHAN
A&B (and CHAN C&D with four-channel BaseStaons). This seng must be physically changed to either RTS, ClearCom, or
BAL and is not adjustable via T-Desk. However, you can view the current placement of switch(es) on the boom of the T-Desk
screen in the Dashboard Status Bar.
