Casella CEL CEL-296 - Manual (Page 58)

Pass band ripple:
< 0.5 dB.
All pass frequency range: (within + 1 to -3dB)
1.5 Hz to 45 kHz.
All pass signal to noise ratio:
Band Lo range
All pass > 73 dB
Hi
range
>95
Octaves > 73 dB > 73
1/3 Octaves > 73 dB > 75
Max input voltage:
Lo range Conditioned 0.45 V RMS
Hi range Conditioned 8.0 V RMS
Input Impedance: 10.5 ka,
Recommended output impedance of input device
Max output voltage:
8.0 V RMS
Output impedance: 511 4,
Recommended input impedance of output device > 10.0 k4.
Use 10 kΩ for exact unity gain.
Loads greater than 10 kΩ may give a slight difference in
output level (less than 0.5 dB).
