Gain on preamplifier

I own a Jolida Fusion preamp. On the tech specification sheet it is stated that the Max output voltage is 20dB. Under that it is stated that the Voltage gain is 30 V.  I am unable to reconcile this.  Is it possible that there was a typo and the descriptor and spec are reversed? If starting at 1 V input, it seems to me that going to 32 V would represent 30dB gain, 20 V aprox 26-27dB gain, given 6dB gain for each doubling of V.  I have been operating on the assumption that the gain was 20dB as the volume setting on the pre driving my BEL 1001MK5 (which provides 26 dB gain) was usually operated between the 6 and 11 o'clock position.  Thanks in advance for any edification.
