The 'Phase' control featured on all subwoofers enables the alignment of the main loudspeaker/
subwoofer combination in the time domain. The phase can be adjusted between 0, 90, 180 and 270
degrees.
Input Section
All loudspeaker models have an input sensitivity trimmer - except the 6020A and HT205 which
have a front-mounted level control. The two-way loudspeakers and subwoofers feature an unbal-
anced non-inverting RCA input as well as a balanced line XLR input. Large three-way loudspeak-
ers only have an XLR input whereas the subwoofers have an additional XLR link out connection.
Power Section
The mains power section comprises a voltage selector (country dependent voltage selection), an
IEC mains input socket and an On/Off switch.
Remote Control Section
Genelec Home Theater products have a power management section that allows the installer to
enable or disable the 'Autostart' function as well as the 'Power' and 'Standby' indicator LED's on
the front of the loudspeaker enclosure. Two types of remote switching terminals are also included:
a 12V trigger function and a contact closure function operated via an external switch or relay as
is often found on home theater automation systems. For details of the features provided in each
model, see Table 3.

Electrical Requirements

The nature of the active technology in the product design means that the electrical power requirements
are generally much lower than a passive system and amplifier with an equivalent SPL output. Idle cur-
rents are kept low and long-term full power output is limited by driver protection. However, some care
should be taken that the start-up current is kept under control, so sometimes a staged turn on may be
necessary for large systems without soft start, for example, 7x HT312A and 2x HTS4B. Table 4 lists
