7.1. AMP SETTINGS

Here you can make general settings for the amp.
① MODE (PC-DI series only)
This specifies whether the connected speaker is Hi-Z (high impedance) or Low-Z (low impedance). High
impedance can be selected for 70V systems or 100V systems.
② HPF (Hi-Z) (PC-DI series only)
This specifies the HPF (high pass filter) that is compulsorily applied for Hi-Z (high impedance). The cutoff
frequency can be selected as either 40 Hz or 80 Hz.
③ BRIDGE
This specifies whether adjacent odd-numbered and even-numbered channels will be bridge-connected to operate
as a high-power amp. If this is ON, the amp gain is 6 dB higher than when it is OFF.
NOTE
• If bridge-connected, only channel A and channel B of the processing parameters are used.
④ CHANNEL SLEEP
If this is ON, channels that are not being used that day can sleep in order to conserve power and prevent
overheating.
⑤ SENS./GAIN (input sensitivity / amp gain)
This specifies the input sensitivity or amp gain.
The input sensitivity can be selected as either 4 dBu or +14 dBu, and the amp gain can be selected as either 26
dB or 32 dB.
