 TASCAM DA-78HR

6 - Monitoring 

NOTE

We strongly advise you to read this section – the 
effective use of multitrack monitoring is one of the 
keys to an efficient recording session. 

Like all multitrack recorders, the DA-78HR has a 
number of different monitoring modes, depending on 
the current monitor status, transport status and 
whether the  track is armed  or not.

When a DA-78HR track is in playback mode, the 
monitoring is off-tape.

The controls which affect monitoring are:

ALL  INPUT

AUTO MON

In addition, there are two menu items affecting the 
monitoring:

shuttle monitor

shuttle mute

6.1 ALL INPUT

When this is active, the signal from the DA-78HR’s 
outputs will always be the appropriate input source 
signal for all tracks. 

When the 

ALL INPUT

 key is pressed, its indicator 

will light. Monitoring for all tracks will be source 
monitoring, rather than off-tape. 

6.2 AUTO MON

This mode is primarily used in punch operations. 
When auto monitor mode is entered (by pressing the 

AUTO MON 

key), the 

AUTO MON 

indicator lights.

This automatically changes the monitoring on armed 
tracks from off-tape to source when recording or 
rehearsing a  recording, and back to off-tape when the 
punch-out point is reached.

6.3 Shuttle monitor

In addition to these modes, there is one further set-
ting, that affects monitoring, but only in one special 
case – shuttle mode. Usually, when shuttling the tape, 
you will want to monitor off-tape. However, if a track 
is armed, you may want to listen to the source input 
signal, rather than the off-tape recording.

NOTE

ALL INPUT overrides  any  shuttle  monitoring  selec-
tions described below. Any shuttle monitoring while 
ALL INPUT is on will always be source monitoring.

The shuttle monitor mode has no effect when 

AUTO 

MON

 is off. 

When the 

AUTO MON

 and

 

shuttle monitoring are 

both on, the output from all armed  tracks  will be the 
source input.

If 

AUTO MON

 is on, but shuttle monitoring is off, all 

armed tracks will monitor off-tape in shuttle mode.

You can also disable off-tape shuttle monitoring with 
the Shuttle Mute function (6.3, “Shuttle monitor”)

.

Shuttle monitoring is attenuated by 12 dB compared 
with other monitoring modes. This helps to avoid 
damage to tweeters, etc. when shuttling fast.

6.3.1 Enabling and disabling shuttle 

monitoring

1

Press the 

SHIFT

 key so that the 

SHIFT

 indicator 

is flashing.

2

Press the 

MENU

 key until the display shows 

AUDIO. 2--

 (

).

3

Press the 

SUB MENU

 key until the display 

shows 

ShTL. MoN. ; 

(

SHTL MON x

, where 

can be 

1

 

(on) or

 (off).

4

Use the 

 or 

 key to change the value to 

1

 

(shuttle monitoring enabled) or 

0

 

(shuttle 

monitoring disabled).

6.4 Shuttle muting

It may be sometimes desirable to mute off-tape out-
put when shuttling. The shuttle mute function allows 
you to do this:

1

Press the 

SHIFT

 key so that the 

SHIFT

 indicator 

is flashing.

2
