Connecting the speakers

Before hooking your MASK onto it’s base, don’t forget to set the proper voltage tap setting.

To use your MASK4 with a normal (hiﬁ) stereo ampliﬁer you have to switch the voltage tap

to 16 ohms. In this case you can easily connect 8 MASK4 to a stereo ampliﬁer channel

capable to drive a speaker load of 4 ohms.

Each doubling of the distance between the MASK and the listener results in a loss of 6 dB.

With the example from above, at two meters, only 94dB are left when driving your loud-

speaker with 10 watt and 88dB at 4 metres.

So you can calculate the necessary tap setting.

In a 100V setup you have to select one of the four 100V tapings (2,5 – 5 -10 or 20 watts).

Each doubling of ampliﬁer power fed to your loudspeaker, increases the SPL by 3dB. So, a

loudspeaker which produces 100dB with 10 watt input at 1 meter, produces 103dB SPL at

1 m, when you feed him with 20 watts.

In 100V systems, the total selected power connected to the 100V ampliﬁer should never

pass the max. power of this ampliﬁer.

To get good intelligibility, you need an SPL of about 10dB above the back-ground noise.

Be sure to install sufﬁcient loudspeakers and avoid death spots, so you don’t have

to pump up the volume too much.

The T-models of the MASK6 can be set to 16 ohm to use with stereol (hiﬁ) ampliﬁers.

For 100V systems the MASK6 has four 100V tapings (6 -15 -30 - 60 watts).
