Tape Equalizer Curves
Each tape equalizer setting is unique, the emphasis of the
curves are as follows:
1. NAB/IEC 7.5 Ips
– Bass emphasis
2. NAB/IEC 15 Ips
– Treble emphasis
3. FLAT
– comparatively is the most neutral of the set-
tings
4. IEC/NAB 15 Ips
– Bass and Treble emphasis
5. IEC/NAB 7.5 Ips
– Greater Bass and Treble emphasis
Each of the tape equalizer presets may be modified by the
on-board
low-cut
filter, described in the following section.
Low Cut
The TG Microphone ‘s
Low Cut
filter is more than a rumble
or high-pass filter, and is intended to act as a modifier of the
TG Microphone’s tape equalizer settings.
The
Low Cut
filter toggle switch is found on the lower front
left of the TG microphone’s body. The
Low Cut
filter has two
user selectable frequencies—
50 Hz
or
90 Hz
and an
Out
or
bypass setting.
When either of the
Low Cut
frequencies are activated, the net
effect of the modification is an additional tier of settings apart
from the initial five tape equalizer options, and accounts for a
total of ten curves available per system.
When the
Low Cut
toggle switch is set to
Out
, the filter is dis-
abled or bypassed and has no affect upon the tape equalizer
or the source.
Polar Patterns
The directional characteristic of the TG Microphone is user
selectable. Two polar pattern options are provided—
cardi-
oid
or
omni
, and either is available via a toggle switch from
the upper portion of the microphone’s body, and may be
selected using the supplied pattern select screwdriver.
Cardioid
This unidirectional polar pattern, denoted as a kidney bean
shaped icon, discriminates against source arriving at the rear
of the capsule and to a lesser degree at the sides, in prefer-
ence for sound incident at the front of the microphone.
NOTE:
Proximity effect is a natural occurrence of the car-
dioid polar pattern, where low-end is emphasized when the
sound source is closer to the microphone.
