6-5 Audio Performance
* Performance assumes normal service condition unless otherwise specified
<Normal service condition>
The normal service condition means that the specified power supply is used, where each
component is correctly connected as per the system diagram, and then adjusted according to
the specified level diagram. However, filters and equalizers are off.
Amplification allowance
(For the rated value at 1 kHz)
Analog input/output (Microphone-system) ................................................... Within ±2.0 dB
Analog input/output (Line-system) ............................................................... Within ±1.0 dB
Digital input/output ...................................................................................... Within ±0.3 dB
Amplification frequency characteristic
(Assumes 1 kHz as the reference at Fs=48 kHz and within transmission frequency
range.)
Analog input/output (+4dBu IN)
FS 48 kHz ............................................................................ Within ±0.6 dB (20 to 20 kHz)
FS 96 kHz ............................................................................ Within ±0.6 dB (20 to 40 kHz)
Digital input/output
FS 48 kHz ............................................................................ Within ±0.1 dB (20 to 20 kHz)
FS 96 kHz ............................................................................ Within ±0.1 dB (20 to 40 kHz)
THD+N
(using 22 Hz HPF and 22 kHz LPF/Fs = 48 kHz, 40 kHz LPF/Fs = 96 kHz within
transmission frequency range.)
Reference level input
Analog input/output (Microphone-system) ........................................................Within 0.2%
Analog input/output (Line-system) ..................................................................Within 0.03%
Digital input/output .........................................................................................Within 0.03%
When inputting a level equivalent to reference input level + head room -1 dB
Analog input/output (Microphone-system) ........................................................Within 0.4%
Analog input/output (Line-system) ....................................................................Within 0.2%
Digital input/output ...........................................................................................Within 0.1%
SN ratio
(Using 22 Hz HPF and 22 kHz LPF)
Analog input/output (Microphone-system, -64 dBu input) ............................ 57 dB or more
Analog input/output (Line-system, +4 dBu input) ......................................... 80 dB or more
Digital input - analog output (full scale reference) ...................................... 105 dB or more
* The noise level of the analog input/output is measured using the input at 150 Ω
termination.
Turndown characteristic ........................................................................................ 100 dB or more
(Channel Fader turndown characteristic for the maximum output level at 8 kHz)
LR phase difference (within transmission frequency range) ......................................... Within ±2°
Maximum input level
Analog ...................................................................... +23 dBu (Distortion rate within 0.3%)
Digital ........................................................................ 0 dB FS (Distortion rate within 0.1%)
