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.

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.

NO!

•Do not perform “biamp/triamp connection,” which means connecting separate amplifiers to individual speakers of a speaker system. Doing so may cause damage.
