1.7. Firmware updates

This product is designed to allow its firmware to be updated in order to improve its operability, add functionality, or fix problems. This product has the following two firmware items.
- Firmware of the unit itself
- Firmware of the Dante module

The process of updating the firmware of the unit itself is performed from ProVisionaire Design. The process of updating the firmware of the Dante module is performed from Dante Updater.

For details on the update procedure and settings for the unit, refer to "ProVisionaire Design User Guide."

note NOTE

  • It will be necessary to update other devices depending on the version of each device in the Dante network. For details, refer to the firmware compatibility chart provided on the above Yamaha website.

1.8. Signal processing in the PC-D/DI series

PC-D/DI series units consist of three blocks: INPUT, USER, and SPEAKER PROCESSOR. INPUT specifies the routing, and USER EQ and USER DELAY apply acoustical adjustments. SPEAKER PROCESSOR applies acoustical adjustments as appropriate for the speakers.

1.9. Input sensitivity and amp gain

The PC-D/DI series lets you specify input sensitivity and amp gain settings using two types of input sensitivity or two types of amp gain. Input sensitivity is the input signal level that produces maximum output. When a signal that exceeds the input sensitivity is input, a limiter inside the PC-D/DI series unit is applied. Reducing the volume raises the input sensitivity and lowers the amp gain. Reducing the volume does not change the maximum output.
For example on the PC412-D if you set amp gain to 32 dB, the maximum output will be 1200W and the input sensitivity will be +10 dBu (when speaker impedance is 8Ω). If the volume is not reduced (0 dB), an input of +10 dBu produces 1200W output. Reducing the volume 10 dB makes the input sensitivity of the PC412-D be +20 dBu (= +10 dBu + 10 dBu), and the amp gain will be 22 dB (= 32 dB - 10 dB). An input of＋20 dBu produces 1200W maximum output.
