Features and Controls
414 MKII MIXER
1. POWER switch (on the rear panel): Turns
the 414 MKII on and off.
2. DC IN 12 V connector (on the rear panel):
This is for connection of the provided TASCAM
PS-P414 AC adaptor only.
3. MIC/LINE IN jacks (Channels 1-4): These
1/4" jacks accept unbalanced signals ranging
from –50 dBV (3 mV) to –10 dBV (0.3 V),
depending on the setting of the TRIM control
(#13).
4. INPUT L & R (on the rear panel): These
XLR-type connectors accept balanced signals.
They are mainly intended for use with dynamic
microphones, but the nominal input level may be
adjusted from –60 to –20 dBV depending on the
setting of the TRIM control. Note that if a signal
source is connected to the front MIC/LINE IN
jack corresponding to the XLR-type connector
where a microphone is connected (L=1 or 3, R=2
or 4), the signal input here at the INPUT (L/R)
connector will be ignored by the 414 MKII.
5. GUITAR IN & TRIM control (on the rear
panel): This 1/4" jack has an impedance of
1MΩ and is intended for use with electric gui-
tars, basses, etc. Adjust the gain from this jack to
channels 1 - 4 with the TRIM control here (turn-
ing it clockwise increases the signal level).
6. SUB IN L and R jacks: These jacks are for
cascade connection of an outboard mixer, etc.
The signal input to these jacks is sent to the
MASTER fader. Nominal input level is –10 dBV
(0.3 V).
The SUB IN R jack is also used to accept FSK-
converted MIDI sync signals from devices such
as the optional TASCAM MIDI-Tape
Synchronizer MTS-30.
7. EQ HIGH: These control the tonality of the high
or "treble" frequencies. Turn them to the right to
boost the signal's high frequency content empha-
sizing brilliance or brightness. Turn them to the
Input Section
left to cut the high frequency content, if the sig-
nal sounds too harsh or shrill. The EQ shelving
point is 10 kHz.
8. EQ LOW: Turn the controls to the right to boost
bass frequencies and make the sound relatively
heavy. Turn the controls to the left to cut bass
and make the sound thinner. The EQ shelving
point is 100 Hz.
9. EFFECT 1 send controls: These controls get
their signal from a point just after the channel
fader (i.e., "post fader send") and route the corre-
sponding channel signal to the EFFECT 1 SEND
jack. Turn the control to the right to increase vol-
ume to the EFFECT 1 SEND jack.
10. EFFECT 2/TAPE CUE controls: These con-
trols get their signal after the channel fader and
route the signal to the EFFECT 2 SEND jack, or
are used to adjust the tape playback level sent to
the monitor section, as determined by the
EFFECT 2/TAPE CUE select switch (#19).
11. PAN controls: These controls allow you to
create stereo mixes by sending the signal from
the channel fader in continuously variable
degrees to the left or right sides of the stereo mix
at mixdown time.
12. INPUT select switches: These are used to
control what the source of the channel is:
The upper position (TAPE) is used during mix-
down or bouncing tracks.
The center position is GUITAR, which selects the
source at the GUITAR IN jack (#5).
Turn the guitar TRIM control all the way to the
left.
The lower position (MIC/LINE) is used when
recording microphones/instruments (in tracking
or overdubbing).
13. TRIM controls: These linear controls are used
to set the preamplification level on the
MIC/LINE IN(puts) or INPUT (L, R). When
TRIM is pulled full down, the preamplifier gain
is low, allowing the jack to accept line level
sources such as electronic instruments. As you
push TRIM up, the preamplifier gain increases,
and when you push TRIM full up, the nominal
input sensitivity increases to –50 dBV (3 mV).
