CONNECTIONS

There are different types of audio and video connections used to

connect the receiver to the speakers and video display, and to connect

the source devices to the receiver. To make it easier to keep them all

straight, the Consumer Electronics Association (CEA

) has established

a color-coding standard. Table 1 may be helpful to you as a reference

while you set up your system.

Table 1 – Connection Color Guide

Types of Connections

This section will briefly review different types of cables and connections

that you may use to set up your system.

Speaker Connections

Speaker cables carry an amplified signal from the receiver’s speaker

terminals to each loudspeaker. Speaker cables contain two wire

conductors, or leads, inside plastic insulation. The two conductors are

usually differentiated by using different colors, or stripes, or by adding

a ridge to the insulation. Sometimes the wires are different colors, one

being copper red and the other silver.

The differentiation is important because each speaker must be connected

to the receiver’s Speaker-Output terminals using two wires, one positive

(+) and one negative (–). This is called speaker polarity. It’s important

to maintain the proper polarity for all speakers in the system. If some

speakers have their negative terminals connected to the receiver’s

positive terminals, performance can suffer, especially for the low

frequencies.

Always connect the positive terminal on the loudspeaker, which is usually

colored red, to the positive terminal on the receiver, also colored red.

Similarly, always connect the black negative terminal on the speaker to

the black negative terminal on the receiver.

The HK 3390 uses binding-post speaker

terminals that can accept banana plugs

or bare-wire cables.

Banana plugs are simply plugged into the

hole in the middle of the terminal cap.

See Figure 1.

Bare-wire cables are installed as follows (see Figure 2):

1. Unscrew the terminal cap until the pass-through hole in the collar

is revealed.

2. Insert the bare end of the wire into the hole.

3. Screw the cap back into place until the wire is held snugly.

The HK 3390 features two sets of speaker connections, with each set

allowing connection of a left and right loudspeaker. This allows you to

place a second set of speakers in another room, or even outdoors,

when weather-resistant loudspeakers are used. You may play both sets

of speakers simultaneously, one set at a time or neither set when using

the headphones or making recordings. Use the Speaker 1/2 Buttons to

activate or deactivate each pair of speakers. It is not possible to select

different sources for each speaker pair.

Subwoofer

The subwoofer is a specialized type of loudspeaker used to play only

the low frequencies (bass), which require much more power than the

other speaker channels. In order to obtain the best results, most speaker

manufacturers offer powered subwoofers, in which the speaker contains

its own amplifier on board. Usually, a line-level (nonamplified) connection

is made from the receiver’s Subwoofer Output to a corresponding jack

on the subwoofer, as shown in Figure 3, but sometimes the subwoofer

is connected to the receiver using the left and right speaker outputs,

then the left and right speakers are connected to terminals on the

subwoofer. The same full-range signal is output through both jacks.

Thus, you have the option of connecting each jack to the line-level input

on a separate subwoofer. If you have only one subwoofer with a single

line-level input, connect it to the right Subwoofer Output on the HK 3390.

Connect the Subwoofer Trigger Output for each subwoofer to the

corresponding trigger input on its amplifier. This enables the subwoofer

to turn on or off together with the HK 3390. To further conserve energy,

when the trigger connection is made, turn the Subwoofer Link Switch

on to turn the subwoofer off when the corresponding pair of main

speakers are not being used, such as during muting, when headphones

are being used, or when the main speakers are turned off using the

Speaker 1/2 switch.

Connecting Source Devices to the HK 3390

The HK 3390 is designed to process audio and video input signals,

playing back the audio and displaying the video on a television or

monitor connected to it. These signals originate in what are known as

“source devices,” including your DVD player, CD player, DVR (digital

video recorder) or other recorder, tape deck, game console, cable or
