TASCAM FW-1804
Connections
CAUTION
• When turning on power, move from source to destina-
tion (in other words, turn on the monitoring system last).
When turning off equipment, turn off the monitoring
system first, and then turn off other equipment. This
helps to prevent "thumps" that can damage your ears,
and your equipment.
MIDI Connections
MIDI instruments, controllers etc. should be connected with
their MIDI OUTs connected to the MIDI IN ports of the
FW-1804.
The MIDI OUT ports of the FW-1804 should be connected
to the MIDI IN ports of the external MIDI equipment.
Analog Audio Connections
The MIC connectors may be supplied with +48 V phantom
power. This is switchable for channels 1 through 4 using
the front panel switch.
The LINE connector for channel 8 can be switched to
match the impedance of an electric guitar or bass.
CAUTION
• Always take care when switching the phantom power to
ensure that devices which may be damaged if phantom
power is supplied are not connected to XLR connectors
where phantom power is supplied.
• Microphones should not be connected to or disconnected
from the FW-1804 with phantom power switched on.
• Unbalanced dynamic microphones should never be con-
nected to phantom-powered connectors.
Analog devices such as compressors, etc. may be connected
using standard 1/4" TRS connectors with the INSERT
jacks (channels 1 to 4). Use a special insert "Y" cable for
this, with a TRS 1/4" plug at the foot of the Y (tip = send,
ring = return), and the two branches fitted with an unbal-
anced 1/4" plug.
