INSTALLATION
connect the HK 3485’s Remote IR Output to the source device’s
Remote IR Input, which will pass any applicable remote signals trans-
mitted through the HK 3485 to the source device. This enables you
to control your sources even when the HK 3485 itself is controlled
via an external IR receiver.
To control more than one source device using the Remote IR Output,
connect all sources in “daisy chain” fashion, with the HK 3485’s Remote
IR Output connected to the first device’s Remote IR Input, that device’s
Remote IR Output connected to the next device’s Remote IR Input, and
so forth. See Figure 19.
Figure 19 – Remote IR Input and Output
NOTE: Not all remote-controllable devices are equipped with
compatible IR inputs and outputs. Check with the manufacturer
of the source device for more information on the type of IR
signal expected. The HK 3485 will output a “stripped carrier”
IR signal.
Step Seven – Connect Optional External
Equipment
If you wish to use the HK 3485 with an external power amplifier,
remove the jumpers connecting the Preamp Outputs and Main-Amp
Inputs. Store the jumpers in a safe place in case they are needed in the
future. Connect the left and right Preamp Outputs of the HK 3485 to
the analog audio inputs on the external power amplifier. See Figure 20.
Figure 20 – Preamp Outputs and Main-Amp Inputs
You may adjust the Volume and Tone Controls using the HK 3485’s
front panel or remote.
If you wish to connect an external processor, such as an equalizer, you
may connect it to the Preamp Outputs and Main-Amp Inputs. Remove
the jumpers and store them in a safe place. Connect the HK 3485’s
Preamp Outputs to the processor’s analog audio inputs, and then con-
nect the processor’s analog audio outputs to the Main-Amp Inputs on
the HK 3485.
Alternatively, you may connect the external processor to the HK 3485’s
Tape Monitor Loop. See Figure 14.
Step Eight – Plug In AC Power
Having made all of your wiring connections, it is now time to plug each
component’s AC power cord into a working outlet.
You may plug two devices into the AC Switched Accessory Outlets on
the rear of the HK 3485. See Figure 21. Make sure each device draws
no more than 100 watts. The devices should have their mechanical or
master power switches turned on, and they will power on any time the
HK 3485 is turned on.

Step Nine – Insert Batteries in Remote
The HK 3485 remote control uses two AAA batteries, which are included.
To remove the battery cover located on the back of the remote, firmly
press the ridged depression and slide the cover toward the bottom of
the remote.
Insert the batteries as shown in the diagram, making sure to observe
the correct polarity. See Figure 22.
Figure 22 – Remote Battery Compartment
When using the remote, remember to point the lens toward the front
panel of the HK 3485. Make sure no objects, such as furniture, are
blocking the remote’s path to the receiver. Bright lights, fluorescent lights
and plasma video displays may interfere with the remote’s functioning.
The remote has a range of about 20 feet, depending on the lighting
conditions. It may be used at an angle of up to 30 degrees to either
side of the HK 3485.
If the remote seems to operate intermittently, then make sure the batteries
have been inserted correctly, or replace the batteries with fresh ones.
Step Ten – Turn On the HK 3485
T
he HK 3485 may be turned on from Standby mode by pressing the
Power Switch on either the front panel or the remote. See Figures 23
and 24.
