Crosstalk: –82 dB at 1 kHz.
Input Impedance: Nominally 20
kohm.
Recommended Source Imped-
ance:
10 kohm or less.
Maximum Input Level: +20 dB
at 1 kHz.
Nominal Gain: Unity.
Frequency Response: ±1 dB
from 20 Hz to 20 kHz with filters
set flat and horn equalization off.
High-pass (subsonic/bass) filter
has selectable –3 dB roll-off
points of 50, 100 or 300 Hz (see
Figure 4.2). Constant-directivity
horn equalization network has 3
dB rise at 3.2 kHz with 12.5 dB
peak at 24 kHz (see Figure 4.1).
Both these filters can be switched
off if desired.
A permanent RFI filter with a –3 dB
roll-off at 33 kHz also affects the
response.
