7.0 – Powering the System
The ST-215 subwoofer can be powered from any amplifier with the relevant high & low
pass filter, and limiter settings. However, due to the self-contained nature of the package,
the use of DQ Series advanced system amplifiers is highly recommended. The use of DQ
Series amplifiers provides a neat and flexible system that will encompass all requirements
for the system to function correctly, as well as providing user control for room EQ and
system alignment.
7.1 - Amplifier and Processing Requirements
7.1.1 - Connections
The ST-215 requires only a single amplifier channel. Inputs to the ST-215 enclosure are
on Neutrik SpeakON NL4 as illustrated below.
Two-core cable should be used for connecting ST-215 subwoofers, and the connections
are as follows:
SpeakON connection 1+ 1- 2+ 2-
Drive unit connection LF + LF - Link Through Link Through
The 2+/2- connections are linked through, so using a 4-core cable these can be used as a
pass-through to other loudspeakers.
7.1.2 - Connector Options
The ST-215 is supplied as standard with NL4TMP connectors, which form an IP54 rated
connection when used with the STX series of SpeakON cable connectors. For more
demanding environments, ST-215s can be supplied with other options by special order –
please contact EM Acoustics to discuss your requirement.
