SECTION C : CONFIGURATION OF SUB & SPEAKER MODE
1. SETTING THE MODE AND MAIN GAIN
Before commissioning, check that the mode chosen corresponds to the model of enclosure or
subwoofer connected.
The amplifier must be de-energized and disconnected the mains . These settings are made inside the
device with the cover removed. They can also be carried out by us at the factory when ordering the
device. The default factory setting is «
SUB » mode.
- The « SUB » mode and the « SPEAKER » mode are defined by the position of switch MP1
(shown above).
- Once the mode is set, switch MP5 manages the T-GUARD™ processing (thermal protection
of electronics and speakers).
- In « SUB » mode, the position of the switch MP5 (shown above) corresponds to 700W RMS continuous
output for 12 seconds before triggering the T-GUARD™ thermal protection.
- In
« SPEAKER »
mode, switch MP5 allows you to choose whether LCR300 or LCR500 speaker models
are connected.
- Depending on the output level of your AV processor or preamplifier, you can choose the input
sensitivity level through the master gain switch which is located on the same board. The "0dB" position
provides an overall gain of 29.8 dB.
This position is suitable for the vast majority of configurations . The
"+15 dB" position gives an overall gain of 44.8 dB. It is intended for low-level preamplifiers/sources.
Regardless of the chosen settings and the position of the Volume Control (1) the maximum input level
(XLR and RCA)
must not exceed 22 dBu (9.75 Vrms).
NOTE ABOUT DIGITAL SATURATION : At the moment when the red LEDs are flashing, there is still a margin
of about 10 dB before saturation of the A to D input converter (0dB Fs). When the A to D input convetor
becomes saturated the result is a significant increase in distortion.
