c) Sub Level

In the 0dB position the signal will be passed on 1:1

to the internal ampliﬁer. The Input Sensitivity of the

subwoofer can be adjusted from -60dB to +6dB and

thus allows for a wide volume levelling range.

d) Sub Filter

The upper frequency limit of the unit is variable and can be set to any value

between 50 and 150Hz. The 85Hz marker indicates the recommendation

of Dolby® labs for surround sound settings. In practice a slightly lower

crossover frequency delivers tighter bass response. For typical near-

midﬁeld monitors we recommend 70 to 75Hz as the upper limit.

Please note: These settings do not have an absolute character, as different

satellites and different room acoustics lead to results that cannot be

predicted.
