BLOCK DIAGRAM DESCRIPTION
General functions
Remote sense lines
Line input (–18dB less than the amplifier gain) is allowing remote sensing. You will need to use this
function to have an 18dB gain attenuator near the amplifier. This function enables you to keep the
TDcontroller at the mixing position and still being able to feed an attenuated amplifier voltage (for safety
reasons) to the sense line connector.
Reset
Holding down the three menu buttons (A, B, ) simultaneously will reset the unit. Reset has the same
effect as powering on and off the unit. The unit will mute (hardware) for 5 seconds with all LED’s on. The
unit will then return to the last set-up automatically saved (every 2 minutes).
Resetting the unit from the front panel is needed to change the cabinet family (Press the three buttons to
reset then let go of the ENTER button to enter into MENU 0). In that case you will have to keep the A & B
Buttons until all LEDs light off.
Mute/Solo buttons
Front panel, direct access. The Mute (or Solo) mode is selected in the user menu. Please note that these
MUTEs are soft mute and are therefore not operating output relays.
Display & Indicators
User control of all settings is via two menu scroll pushbuttons, an additional assignable pushbutton, an
assignable rotary encoder and a backlit 16*2 character display.
Three LED’s per channel for sense (green), peak limit (red) protects (yellow). Four dedicated LED’s are
situated alongside the associated MUTE/SOLO button.
Two LED’s to indicate input overload and signal clipping into the DSP.
Default screen will pop up after 2 minutes and display the current set-up.
Contrast adjustment
A hole in the front panel allows the adjustment of the contrast of the LCD screen.
Serial link / Downloader
The unit can be RS232 linked to any PC in order to download new versions of Firmware using a
Windows compatible Downloader program. See corresponding chapter page 32.
