Integra DTA-9.4 - Manual (Page 11)

11
To prevent damage to circuitry, never short-circuit the positive (+)
and negative (–) speaker wire. Never short across the speaker cable
wire and the rear panel.
Caution
• Do not connect any devices other than speakers to these
terminals. Do not short across the output terminals or across the
output terminals and rear panel.
• Be sure not to mistake the positive and negative outputs or the
left and right speakers. Doing so will result in an unnatural sound
space.
• Do not connect more than one speaker cable to one output
terminal. Doing may damage the DTA-9.4.
• Do not connect one speaker to multiple speaker terminals. Doing
may damage the DTA-9.4.
• Note that negative (–) terminals are not ground (GND) potential.
• When you use banana plugs, do not insert the plugs before
tightening the output terminal screws. The loosen screws may
cause sound distortion or no audio output.
• Do not connect one speaker to more than one set of speaker
terminals to avoid parallel speaker connection. Also do not
connect more than one speaker to one set of speaker terminals.
Doing so may cause damage.
• Do not perform “biamp/triamp connection,” which means
connecting separate amplifiers to individual speakers of a
speaker system. Doing so may cause damage.
NO!

Connecting speakers
Before connecting the speakers, place them correctly by consulting
the instruction manuals that came with them. For surround playback,
the configuration and placement of your speakers are very important.
Please note that connecting speakers with a low power input rating
does not produce large sound volumes. For those speakers, large
sound volumes causing excessive input level may damage the
speakers.
Connecting speakers
Connect the red (+) output terminal on the DTA-9.4 to the (+)
terminal on the speaker, and the white (–) output terminal on the
DTA-9.4 to the (–) terminal on the speaker. Use the marking or line
on the speaker cord to connect appropriate terminals. Be sure to
match the speaker polarity for in-phase connection by connecting (+)
terminal to (+) terminal and (–) terminal to (–) terminal between the
DTA-9.4 and speakers. Connecting (+) terminal to (–) terminal
between the DTA-9.4 and speakers leads to reverse phase
connection, causing unclear sound localization (the unstable
positioning of the instruments or singer) or strange sound.
Only connect speakers with an impedance of 4 ohms or greater.
If a speaker with an impedance of less than 4 ohms is connected,
it may damage the DTA-9.4.
Make the connections following the procedure given below.
• When stripping and twisting the wires, be sure not to allow the
insulation and wire materials to enter the ventilation holes of the
DTA-9.4.
