6.4.2 Level Control

Audio level is adjusted by turning the Rotary Encoder while in Master Level Control Mode or Level

Control Mode. The changing value is displayed above the Rotary Encoder or above the DAK being

pressed. Each level control has a range of 0.0 (off) to 10.0 (+12dB approximately), and is adjusted in

steps of 0.5. A value of 5.0 corresponds to approximately 0dB.

The encoder is turned in a clockwise direction to increase a level and counter-clockwise to decrease the

level. When the value 0.0 is displayed, further counter-clockwise movement of the encoder does not

affect the output level or the display (also clockwise movement when 10.0 is displayed).

6.4.2.1 Master Level Control Mode

After a power cycle the panel enters Master Level Control Mode. The display above the Rotary Encoder

shows the current output level, which defaults to 3.0 after a panel cold-start initialisation. The LED

displays above the first 13 DAKs show any centrally assigned mnemonics, and DAK 14 is the REPLY

key. The red LEDs adjacent to the SOFT, LEVEL and SHIFT Pushbuttons are all off.

In Master Level Control Mode a pressed DAK carries out the actions of the assignments on that key. The

central configuration utility has configured the latching, momentary, interlocking ability of each

pushbutton.

The Master Level can also be altered from another mode while the REPLY key is in use. Moving the

Rotary Encoder displays the Master Level on the Rotary LED Display and allows the value to be

adjusted. If the Rotary Encoder is static for 2 seconds after it has been moved, the display reverts to the

original mode. The display also reverts to its original mode if the REPLY is de-activated. The REPLY key

must be de-activated before the original mode of operation can resume

6.4.2.2 Auxiliary Level Control Mode

When the LEVEL Pushbutton is pressed Level Control Mode is selected. The display above the Rotary

Encoder shows the current Auxiliary Level preceded by the letter 'A', and the LEVEL Pushbutton red LED

is lit. Level Control Mode can be selected from Master Level Control Mode or SOFT Mode. In Level

Control Mode the Rotary Encoder is used to adjust the audio level of the auxiliary channel or the listen

levels of DAKs. The Alphanumeric LED Displays above the DAKs show any assigned mnemonics, and

DAK 14 is the REPLY key.

The Auxiliary Level defaults to A3.0, after panel initialisation. The Auxiliary Level is adjusted by turning

the Rotary Encoder and the current value is reflected on the Rotary LED. The Auxiliary Level has a range

of A0.0 (off) to A10 (+12dB approximately), adjustable in steps of 0.5. A value of A5.0 corresponds to

approximately 0dB. The level changes 'smoothly' across the range of values.

If there isn't any Rotary Encoder or DAK action for 10 seconds, the panel reverts to Master Level Control

Mode and the red LED on the LEVEL Pushbutton is cleared.

6.4.2.3 Crosspoint Listen Level Mode

A DAK crosspoint listen level can be adjusted when the level key selected and then a valid DAK is

selected and held; the Rotary LED Display changes to show "DAKL" and the display above the pressed

DAK shows the current crosspoint listen level setting. Only one DAK can be selected at a time; any

further DAK presses are ignored until the first DAK has been released.

Turning the Rotary Encoder changes the crosspoint listen level and the current value is reflected on the

display above the DAK The level has a range of 0.0 (lowest level) to 10.0 (+12dB approximately),

adjustable in steps of 0.5. A value of 5.0 corresponds to approximately 0dB. When the panel is initialised,

the level is set to '5.0' by default.

In the case of a port number being assigned to more than one DAK, the average of the level settings is

calculated to give a resultant listen level.

A DAK with a talk function continues to operate if the DAK was pressed before selecting DAK Listen

Level mode. Talk operation cannot be activated once DAK Listen Level mode has been selected.
