ELECTRONIC SPECIFICATIONS
FREQUENCY RESPONSE
The JH~400B Series Console is rolled off at 20Hz and 20kHz to
minimize room rumble and RF problems in the studio. Any input to
any output will measure better than +~ -~ from 20Hz to 20kHz.
HEAD ROOM
Careful attention has been taken to ensure adequate headroom in
the equalizer and MIX bus section of the JH-400B console. Output
headroom will exceed the capabilities of any tape machine system.
Headroom specs are defined as the number of db between normal
level and the maximum 1kHz sine wave level at .5% T.H.D.

Measured Mike input to channel line output with a 150 ohm source
impedence and lOk ohm output termination-- 72 dB.
CROSSTALK
Crosstalk will vary slightly with the size of the console. High
frequency crosstalk is caused primarily by capacitive coupling
between input lines and summing buses. Low frequency crosstalk
is a function of power supply decoupling and transformer coupling.
I/0 MODULE LINE INPUT TO MIKE CROSSTALK
This measurement is a measure of crosstalk between the monitor
channel and the Mike channel of a module with the module in
TAPE mode. It is made with a 150 ohm resistor terminating the
Mike Input and a +4dBv signal into the channel line input.
at 1kHz, 60db below +4dBv
at 18kHz, 38db below +4dBv
