I think you may be misunderstanding how professional audio levels work Craig. That piece of kit will probably be designed to work at a nominal operating level of +4dBu and peak levels would be somewhat higher. If it was feeding a digital system then the analogue level for 0dBFS would probably be somewhere between +18 and +24dBu. So you end up with a dynamic range into the ADC of something like 119dB which is better than all but the highest performance convertors.
