B. GAIN MIN, PAD ON
q Gain (CH1~12)
w Distortion ratio (CH1~12)
e Noise level (CH1~12)
Parameter Short the CH IN being measured with
150 Ω.
r INSERT OUT Gain (CH1~12)
t INSERT IN Gain (CH1~12)
Parameter Input the signals to the INSERT IN being
measured.
y Odd channel/even channel crosstalk
Parameters Input the signals to the odd channels side.
Short the even channel side with 150 Ω.
The even channels must be the same too.
C. Phantoms (CH 1~12)
Short XLR Pin 2 and Pin 3, connect a 10 kΩ load
between Pin 2-1, then switch the Phantom switch
On. The voltage is regulated to be no more than the
following.
Check that when the Phantom switch is switched
Off, the discharge starts quickly.
2-8. CH IN 13~16 (PHONE)
Parameter Inspect with STEREO OUT L (XLR).
A. GAIN MAX
q Gain (CH13~16)
e Distortion ratio (both L/R)
r Residual noise (both L/R)
Parameter Short 2TR IN ANALOG with 150 Ω.
t L/R level difference
The range for the difference in the gain measured
with q is regulated as follows.
y Crosstalk between left and right
Parameter Input the signals to the left side.
Short the right side with 150 Ω.
The right side must be the same.
2-7. CH IN 1~12 (XLR)
Parameter Inspect with STEREO OUT L (XLR).
A. GAIN MAX, PAD OFF
q Gain (CH1~12)
w f characteristic (CH1~12)
Parameter The permitted range uses 1 kHz as
the reference.
e Distortion ratio (CH1~12)
r Noise level (CH1~12)
Parameter Short the CH IN being measured with
150 Ω.
However, if the permitted range above is not met, EIN
Measurement value (Gain at 1 kHz) must be -128
or more.
t Level difference (CH 1~12)
The range for the difference in the gain measured
with q is regulated as follows.
