Connecting External Devices

The M-48 supports REAC EMBEDDED POWER. When the M-48 is connected to the S-4000D via a REAC cable, power will be
supplied via the REAC cable.
REAC EMBEDDED POWER is technology that uses a Cat5e cable to supply not only REAC audio signals but also power to a REAC
device. REAC devices that support REAC EMBEDDED POWER do not require an AC adaptor or AC power cord to provide power;
simply connecting the REAC cable will provide REAC communications as well as power supply.
Once the connections have been completed, turn on power to your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.
* This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate
normally.
* Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still
hear some sound when the power is switched on, but this is normal and does not indicate a malfunction.
