Phantom power (left) and Low Cut filter DIP switches
Low Cut Filter (Rolloff)
Within the DIP switch block used for gain settings is the Low Cut filter switch.
It provides a low frequency rolloff at 85Hz that can be used to minimize low
frequency artifacts such as vibration noise and rumble. Move the switch to
the down position to engage the rolloff. In the up position (marked F
lat
),
the low cut filter is not engaged; the audio signal passes through the circuit
unchanged.
AV-M8 Rear Panel
The rear panel of the AV‑M8 Mic Input Module contains the AC power
connector (with fuse), power LED, A‑Net connections, stereo link DIP
switches, clock source selection, and the ADAT® optical I/O.
Power Connector
The AV‑M8 Mic Input Module uses an internal switching‑type power supply.
This type of power supply can be used worldwide with a wide range of AC
wall current output voltages (100‑240VAC). When travelling internationally,
you do not need to replace the power supply in countries where voltages are
different. You may, however, need plug adapters to allow the power supply
to be connected to wall outlets in some countries, since many countries
use different physical plug layouts for their power systems. Optionally, the
detachable IEC power cord can be replaced with one that matches the local
power system.
