post outputs are provided.
•A high pass filter switch that cuts frequencies below 20 Hz, and detented attenuators and level meters for
channels A and B are provided.

The PC3301N enables parallel connection of multiple high-impedance speakers that support 100 V line
output.
An optional external amp control device, such as the ACD1 or ACU16-C, enables you to monitor or control
the amplifier via a network. For the latest information about amp control devices, please visit our website:
