3 - Connections : Analog connections Analog connections Mic/line connections All these connections (microphone and line) are balanced. The XLR connections follow the standard of pin 1 ground, pin 2 hot and pin 3 cold. The TSR 1/4" jacks are tip hot, sleeve ground, ring cold (this applies to all balanced 1/4" jacks on the DM-4800). Both the XLR mic connection and the 1/4" jack connection can be made at one time, but it is only possible to accept input signals from one source at a time. The choice between the mic and line inputs is made with the MIC/LINE selector switches for each input channel. Figure 3.2: Analog channel inputs and controls Note that the switch also has a -20 position, providing a 20dB pad for high-output microphones. The analog input signal level can be adjusted using the analog TRIM controls (there is also an internal software digital trim control for each input channel, independent of these analog controls). A +48V phantom power supply is provided for balanced condenser microphones. This is switchable in groups of 4 (inputs 1-4, 5-8, 9-12, 13-16, 17-20, and 21-24). WARNING To avoid damage to the microphones and/or the DM4800, do not connect or disconnect condenser microphones to and from the DM-4800 with the phantom power to that input switched on. Always switch the phantom power off before connecting or disconnecting condenser microphones. Do not use unbalanced dynamic microphones connected to the XLR connectors with the phantom power turned on. This may cause damage to the microphones and/or the DM-4800. The 1/4" balanced input jacks accept +4dBu connections, but you can use the TRIM controls to allow them to accept -10dBV connections (from synthesizers, etc.). Note that if additional analog inputs are required, the optional IF-AN/DM slot card can be used to provide such inputs. TIP Signal/overload indicators for the input channels are selectable in the preferences screen. See "OL/STATUS LED TYPE" on page 42 for full details. Channel inserts The analog inserts for each analog input channel allow you to use your favorite analog compressors/gates, etc. before the sound gets converted to the digital domain. NOTE These are not the same as the "soft" (assignable) insert loops which are described in "Insert patching" on page 61. These 1/4" jacks are wired: tip send, ring return, sleeve common ground.

ASSIGNABLE RETURNS These are pseudo-balanced 1/4" TRS jacks at +4 dBu (wired as described above). As the name suggests, they provide analog return inputs which can be assigned to a variety of sources (see "Routing" on page 59). TASCAM DM-4800 User's Manual 49

3 – Connections : Analog connections

TASCAM DM-4800

User’s Manual

Analog connections

Mic/line connections

All these connections (microphone and line) are bal-

anced. The XLR connections follow the standard of

pin 1 ground, pin 2 hot and pin 3 cold. The TSR 1/4"

jacks are tip hot, sleeve ground, ring cold (this

applies to all balanced 1/4" jacks on the DM-4800).

Both the XLR mic connection and the 1/4" jack con-

nection can be made at one time, but it is only possi-

ble to accept input signals from one source at a time.

The choice between the mic and line inputs is made

with the

MIC/LINE

selector switches for each input

channel.

Note that the switch also has a

–20

position, provid-

ing a 20dB pad for high-output microphones.

The analog input signal level can be adjusted using

the analog

TRIM

controls (there is also an internal

software digital trim control for each input channel,

independent of these analog controls).

A +48V phantom power supply is provided for bal-

anced condenser microphones. This is switchable in

groups of 4 (inputs 1–4, 5–8, 9–12, 13–16, 17–20,

and 21–24).

WARNING

To avoid damage to the microphones and/or the DM-

4800, do not connect or disconnect condenser micro-

phones to and from the DM-4800 with the phantom

power to that input switched on. Always switch the

phantom power off before connecting or disconnecting

condenser microphones.

Do not use unbalanced dynamic microphones con-

nected to the XLR connectors with the phantom power

turned on. This may cause damage to the microphones

and/or the DM-4800.

The 1/4" balanced input jacks accept +4dBu connec-

tions, but you can use the

TRIM

controls to allow

them to accept –10dBV connections (from synthesiz-

ers, etc.).

Note that if additional analog inputs are required, the

optional IF-AN/DM slot card can be used to provide

such inputs.

TIP

Signal/overload indicators for the input channels are

selectable in the preferences screen. See “OL/STATUS

LED TYPE” on page 42 for full details.

Channel inserts

The analog inserts for each ana-

log input channel allow you to use your favorite ana-

log compressors/gates, etc. before the sound gets

converted to the digital domain.

NOTE

These are

not

the same as the “soft” (assignable) insert

loops which are described in “Insert patching” on

page 61.

These 1/4” jacks are wired: tip send, ring return,

sleeve common ground. The nominal send and return

levels of these inserts is –2dBu which allows them to

be used with a wide range of studio equipment.

2 TR IN

This pair of unbalanced RCA jacks pro-

vides a –10dBV return for the analog outputs of a 2-

track recorder connected to the DM-4800.

ASSIGNABLE RETURNS

These are pseudo-bal-

anced 1/4" TRS jacks at +4 dBu (wired as described

above). As the name suggests, they provide analog

return inputs which can be assigned to a variety of

sources (see “Routing” on page 59).
