Operating instructions

2.1 INPUT CONNECTIONS
Connect source components and recorder according to the diagrams in the following pages. If using a
turntable, connect it to PHONO input only. If the turntable is equipped with a ground wire, connect it to the
g
round terminal next to the PHONO input by unscrewing the terminal then inserting wire and tightening the
screw terminal onto the wire.
Do not
use “RCA-compatible” connectors that have a hollow center pin with a hole at the tip. Inserting
them into the Integrated 225’s RCA jacks can cause internal damage.
2.2 SPEAKER CONNECTIONS
Depending on the level of the input signal, the voltage at the outputs can be high enough to cause electric
shock – be sure that power is turned off when connecting or disconnecting anything. As well, be sure that
the speakers are rated for use with this amplifier – an overdriven speaker can pose a fire hazard.
Connect the red (+) connection on the speaker to the red (+) binding post on the amplifier, and the black (–)
connection on the speaker to the black (–) binding post on the amplifier using cable that is insulated to
handle the maximum output of the amplifier. Do not overtighten the binding posts as this may cause damage.
The binding post pair accepts a connection from one speaker.
2.3 TRIGGER
This feature allows the amplifier to be turned on or off remotely via the trigger. The 3.5mm (.125”) mini-jack
INPUT receives a 12V signal from an upstream component or system controller. The same trigger signal can
be linked to other components through the OUTPUT.
2.4 INFRA-RED RECEIVER
External IR receivers allow the Remote Control to be used from other locations in your home. Once an IR
receiver is wired to another room, connect it to I.R. RECEIVER IN. The signal can be linked to other
components through I.R. RECEIVER OUT.
2.5 POWER
After the system is connected use the supplied power cord to connect power. It is normal for a “click” to be
heard from inside the chassis when connecting power.
