10. Analog Inputs / Outputs
10.1 Mic / Line In
The OctaMic II has 8 balanced Mic and Line inputs via 1/4" TRS (stereo) and XLR combo jacks
on the rear panel. The electronic input stage is built in a servo balanced design which handles
unbalanced and balanced signals correctly, automatically adjusting the level reference.
XLR
The pin assignment follows international standards. With XLR, pin 2 is + or hot, pin 3 is – or cold,
pin 1 is ground. Pin 1 is connected to the chassis directly at the socket (AES48).
When using unbalanced cables be sure to connect pin 3 (-) to 1 (ground). Otherwise noise
may occur, caused by the unconnected negative input of the balanced input.
The OctaMic II offers an adjustable amplification from +6 dB up to +60 dB. This equals a sensitivity
of +13 dBu down to –41 dBu, referenced to full scale of the AD-converter.
The soft switching, hi-current phantom power (48 Volt) provides a professional handling of con-
denser microphones. The usage of a hi-end integrated circuit (That 1510) guarantees outstanding
sound quality, lowest THD, and maximum Signal to Noise ratio in any gain setting.
The OctaMic II's 'overall' amplification from analog input to analog output depends on the analog
output reference setting. The EIN is not affected by this setting, since the S/N ratio scales 1:1 with
the output amplification.
The input impedance is 3.3 kOhm.
TRS
The pin assignment follows international standards. With TRS, tip is + or hot, ring is – or cold.
When using unbalanced cables with stereo TRS jacks, the 'ring' contact of the cable's jack
should be connected to pin 1 (ground). Otherwise noise may occur, caused by the uncon-
nected negative input of the balanced input.
The TRS jacks have a fixed level attenuation of 9 dB. Based on the adjustable amplification from
+6 dB up to +60 dB, the sensitivity is +22 dBu down to –32 dBu, referenced to full scale of the
AD-converter. Therefore the TRS inputs are true full level Line inputs, and the unit can also be
used as Line amplifier.
The TRS jacks are free of phantom power. The balanced input impedance is 8.4 kOhm, 4.2 kOhm
unbalanced.
