TASCAM DM-4800
User’s Manual
Analog outputs
The dedicated analog outputs are relatively few,
since it is expected that most signals will remain in
the digital domain after they have entered the DM-
4800.
STEREO OUT
Balanced XLR connections (1
ground, 2 hot, 3 cold), which output the stereo buss
signals, which can be used to feed the analog inputs
of a 2-track recorder, or a specialist chain of analog
devices used for mastering.
NOTE
There are no dedicated stereo digital outputs. The ste-
reo buss may be routed internally to a variety of digital
outputs in different formats. See “Output routing” on
page 61 for details.
ASSIGNABLE SENDS
These are pseudo-bal-
anced 1/4" TRS jacks at –2 dBu (wired as described
above). As the name suggests, they provide analog
send outputs which can be assigned from a variety of
sources (see “Routing” on page 59).
Monitoring (LARGE (BAL) & SMALL
(BAL))
Two pairs of balanced 1/4" jacks provide
feeds to the stereo control room monitoring systems
(amp/speaker or powered monitors) at +4dBu levels.
The level is adjusted using the hardware
CR
control
and the levels can be adjusted individually, and
switching between the two sets of speakers is per-
formed using a dedicated top panel key.
Monitoring (STUDIO (BAL))
This pair of bal-
anced 1/4" jacks provides a+4 dBu feed to the studio
monitoring system. The level is controlled by soft-
ware from the
MONITOR/MONITOR
screen.
Digital connections
Digital audio I/O
TDIF I/O
There are three 25-pin TDIF-1 connectors
each carrying eight channels of input and eight of
output. These can be used to connect DTRS record-
ers, etc. as well as other devices whose digital I/O
conforms to the TDIF-1 standard.
WARNING
Make connections to these terminals only using
approved TDIF cables. Use of any other cables will result
in signal degradation, and may even damage equip-
ment.
ADAT “lightpipe” OUT & IN
These TOSLINK
optical connectors carry eight output channels and
eight input channels of audio respectively.
Connect them to appropriately-equipped equipment
using standard optical digital audio cables.
CASCADE
This is a special connector, used only to
connect another DM-4800 unit, to extend the capa-
bilities of the DM-4800.
WARNING
Only use the special TASCAM cascade cable here. Use of
any other type of cable may result in damage to the
equipment.
Digital inputs and outputs
There are two sets
of stereo digital inputs and two sets of stereo digital
outputs.
Each set comprises an unbalanced RCA connector
(typically for use with S/PDIF equipment), and an
XLR connector (typically for use with AES/EBU
equipment).
Though connections can be made to both the RCA
and XLR connectors together, only one can be used
for input at any one time (output from these jacks is
made in parallel). Selection is made in software.
We strongly recommend that to maintain signal qual-
ity, you only use cables designed for digital
equipment.
