CAUTION!
When using the Speakon type lead, connect the Red wire to the
positive terminal of the Left Main Speaker and the Yellow
wire to the positive terminal of the Right Main Speaker.
The Black wire is connected to either one of the negative
Terminals of the Left or Right Main Speakers.
DO NOT CONNECT BLACK WIRE TO BOTH TERMINALS!
Please Note:
The Speakon type lead (used for High Level
Input) referred to is included and pre-wired ready

Connect the Sub to the amplifier
Either using the Low Level Input (RCA)
or the High Level Input (Neutrik Speakon)
SEE WARNING ON PAGE 9
The digital display on the rear panel shows that the unit is powered and the amplifier is ready for
use. Please note that the display will remain lit for a short while following switch-off whilst the
power is dissipated from the internal power supply. The fuse is located below the main input
connector. The fuse should only be replaced, when required, with one of the same type and
rating as installed.
NOTE
If the
Reference
150
is to be in standby mode for extended periods then it is advised that the
system main power switch is turned off. This will ensure the complete isolation of mains power
to the circuits and result in zero power consumption. Please ensure that the system is powered
off via the power switch when making and disconnecting all input cables.

WARNING!!
The High Level Lead must be used with zero voltage referenced amplifiers. The new bread of amplifier
that employ Digital output stages requires an interface which is available as an optional extra. If there is
doubt whether your AV amplifier has digital output stages then please check with the amplifier manufac-
turer’s customer services department. Most companies are very helpful and will be able to confirm this for
you.
