1. Setting Audio System
There are three basic ways you can use the T-FBK4 combine with your audio system.
It can be:
1)
.
Connected to a MIC channel of a MIXER, into the "Insert" jack (send/return).
2).Connected to the SUBGROUP/MAIN OUTPUTS (L/R) of a MIXER into the "Insert" jack
(send/return).
The connection of T-FBK4 to Insert points, is probably the best selection, the levels present in
most mixers are pre-fader, (normally 10 dBu) and flow direct to T-FBK4.
In this way any fader level variations do not modified the setup of T-FBK4.
--- For the best performance and proper operation, the average input signal should consistently
light up at the 0dBu LED and the +10dBu LED lighting occasionally.
3).Connected "ON LINE" between mixer and PA system. From output of the Mixer to input of
T-FBK4 and from Output of T-FBK4 to PA input (Stereo Amplifier).
The above setup is used when insert points are not available, set the T-FBK4 at +4dBu, this value
is correct when you connect the outputs of any mixer directly to the input of T-FBK4.
--- For the best performance and proper operation, the average input signal should constantly
light around 0dBu LED and the +10dBu LED should light only occasionally.
2. SETUP & LIVE Mode
The T-FBK4 offers a total number of 24 notch filters for each channel (CH 1/CH 2) and two main
operation modes:
a. SETUP mode, with the fixed filters.
b. LIVE mode, with the free filters not used in SETUP mode.
The SETUP mode is used to detect and remove feedback problems in the audio system due to the
microphone placement, different environments shapes, etc.
Once these filters are set, they can't be removed unless you reset then again.
The LIVE mode is used to detect and remove feedback in "real-time", during the musical events.
The free filters, not used in SETUP mode, automatically work in LIVE mode, the last filter included
blink.
1). Using SETUP Mode (SOUND CHECK)
Fixed filters are set before a performance in a process called ringing out a system, this is done
after all other setting system has been done.
a- First, bring down the main mix, turn off all music sources and open the MIC (if you use Vocalist)
or the different MIC (if you use a Sub-Group).
b- Place the T-FBK4 in SETUP Mode by pressing and holding the CLEAR/SET UP button for more
than 3 seconds.
c- The CLEAR/SET UP LED will start flashing, indicating SETUP mode is selected for CH1 or CH2 or
together.
d- Set the level of each CHANNEL with PFL and slowly turn up the Main Mixer Volume, raising the
gain of the system, until feedback occurs.
