5. Setting procedure
5.1 Output level setting
1- Set the Left and Right potentiometers on the front panel to the maximum position to take full advantage of the amplifier's dynamic range.
This control can be used when the sound level is intentionally limited by the installer. The overall sound level can be modulated using the
VCA (remote volume control).
2- Flex Power
2120
has a sufficient power reserve for the amber LEDs to flash briefly.
3- If the LED remains amber too often, the limiter comes into action, and the sound can then deteriorate.
5.2 Input level setting (input 1 to 4)
Flex Power
2120
is equipped with a line preamp and a mic preamp with a wide dynamic range that must be adjusted independently.
1- Connect a standard source (like CD) and choose a high dynamic range.
2- Set the input volume (Level) on the facade of each input as desired. The LED can turn amber briefly on a very high peak level. If the LED is
regularly red (risk of saturation and sound deterioration), decrease the volume.
3- If a microphone is used, connect it to the dedicated inputs (mic).
4- Position the microphone.
5- Set the mic input sensitivity (mic gain) at the rear of the device until the desired volume is obtained. Follow the same procedure as in point 2.
5.3 Signal and clipping LEDs: state of inputs 1 to 4
•
LED off: no signal or volume at 0.
•
LED green or briefly flashing amber: optimal usage range.
•
LED amber steady: risk of clipping and distortion. Decrease the volume.
5.4 Vox sensitivity (Input 1) and priority
1- Connect a microphone to input 1.
2- Use the microphone in real configuration: speak normally close to the microphone.
3- Increase the Vox button sensitivity on the rear panel until the Vox priority input is activated while speaking.
4- If the Vox input is activated undesirably, decrease the sensitivity.
5.5 Setting the tone
Flex Power
2120
has Bass/Mid-range/Treble tone controls to adapt the sound according to the acoustics of the room and/or the enclosures,
or according to the type of tone desired.
