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.

For details on these types of processing, refer to the sections of "PROCESSING screen."

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.

■When the PC412-D’s amp gain setting is 32 dB

3. Preparations

3.1. Precautions for rackmounting

This product is guaranteed to operate in a temperature range of 0–40 degrees. If only this product is being

mounted in an EIA standard rack, multiple units can be mounted without leaving space between them. If this

product is being mounted in an EIA standard rack together with other devices, heat from each device might

cause the temperature inside the rack to rise, preventing this product from operating to its full potential. To

prevent heat buildup inside this product, you must observe the following conditions when mounting it in a rack.

• If this product is mounted together with devices that tend to become hot, such as power amps made by

other manufacturers, leave 1U or more of space between this product and other devices. Install a

ventilation panel in this space or leave it open to ensure sufficient airflow.

• Since this product takes in air at the front and exhausts it at the back, you should not rack-mount it

together with devices that take in air at the back and exhaust it at the front.

• Leave the back panel of the rack open, and keep the rack at least 10 cm away from the wall or ceiling to

ensure sufficient airflow. If the back panel of the rack cannot be left open, attach a commercially available

fan kit or other forced air exchange device. If a fan kit is installed, closing the back panel of the rack might

increase the heat dissipation effect in some cases. For details, refer to the owner’s manual of your rack

and fan kit.

3.2. Filter element and grill installation

Install the included filter elements and grills. Note that the size of the filter elements differs between left and

right. The grills are held in place magnetically, and can be easily attached.

Fit the filter elements into the brackets of the unit; then attach grill "L" to the left side of the unit’s front panel and

attach grill "R" to the right side of the front panel.

3. Preparations

4.5. High impedance connections (PC-DI series only)

The PC-DI series also supports high impedance (100V/70V line).

■ Number of speaker systems that can be driven

As long as the total rated input of the speaker systems used is within the output value of the power amp, any

number of speaker systems can be connected in parallel.

When using high-impedance connections, the rated input of the speaker system is determined by the settings of

the speaker transformer used with the speaker system.

If using the 600W output PC406-DI with a speaker system whose rated input is 20W due to the attached speaker

transformer, calculations * show that we can use up to 30 speaker units per channel, and up to 120 speaker

system units for the total of four channels.

A combination of speaker systems with different rated input can also be connected.

* In consideration of impedance variance in the primary side of the transformer, future change in transformer

tap, and future addition of speakers, we recommend that you allow a margin of about 20%.
