Even if you don't plan to set up a surround system, adding a subwoofer can be a real advantage for stereo mixing. If you

can't hear the extreme low end there's not much you can do to make it sound great. The extended bass response provided

by a good subwoofer can indeed help you to improve the overall quality of your mixes.

The location of your subwoofer is not as critical as the main speakers, because frequencies below around 200 Hz — the

region your subwoofer will be working in — aren't directional. To say it another way, the ear can't locate the source of such

low frequencies, so in theory the subwoofer can be placed anywhere in the room. In reality it's a good idea to place the

subwoofer on the ﬂoor somewhere between the main front speakers at the same distance from the listening position as the

main speakers, but it doesn't have to be dead center.

Fine-tuning for Stereo + Subwoofer

Set the HS50M or HS80M LEVEL control to about 12 o'clock to set the nominal input level to approximately +4dB. If

you're using the HS50M set the HS10W LEVEL control to about 10 o'clock, and if you're using the HS80M set it to

about 11 o'clock. You can then ﬁne-adjust the HS10W LEVEL control as required. Another approach would be to adjust

the HS50M/HS80M output level to achieve the desired relativebalance with the subwoofer.

Start with the HIGH CUT control set at its center click position, which corresponds to a HPF frequency of about 100 Hz.

The HIGH CUT frequency can be adjusted later to achieve the smoothest integration with the HS50M or HS80M

speakers.

Turn the HS10W LOW CUT switch ON. Adjust the LOW CUT control to achieve the desired degree of bass extension.

Set the HS50M/HS80M LOW CUT switch to "FLAT".

When set to "-2 dB" the HS50M/HS80M EQ MID switch attenuates the midrange frequencies slightly to produce a

somewhat "softer" sound that may be better for listening or long monitoring sessions. For accurate monitoring,

however, set the MID switch to "0".

Set the HS50M/HS80M ROOM CONTROL switch according to the distance your speakers are placed from the nearest

wall (refer to "Proximity to Walls and Corners", above).

For accurate monitoring set the HS50M/HS80M HIGH TRIM switch to "0". This switch can be set to "-2 dB" to

attenuate the highs slightly if you ﬁnd the sound too bright.

If you're going to be mixing for surround, obviously you'll need a surround

monitoring system. For a 5.1 surround system, for example, you only need to

add a center speaker and two rear speakers to the stereo + subwoofer

system described in the previous section. Let's see ... two main speakers

plus one center speaker plus two rear speakers is a total of ﬁve

speakers, and ".1" refers to the subwoofer. All present and

accounted for!

According to the ITU (International Telecommunications Union)

speciﬁcations for 5.1 surround setup, the main front speakers are

positioned in the 60° equilateral triangle relationship to the listening

position described earlier, and the rear speakers should be located at

the same distance from the listening position, but at an angle of between
