Model ALTx-WIRi 20

ALTx-WIRi 20 UltraMatch™音量控制器是一款壁掛式音響

揚聲器音量控制，內置紅外接收器。

概論 Overview

The ALTx-WIRi 20 UltraMatch™ Volume Control is a wall-mount stereo speaker-level volume control with built-in IR Receiver. It connects between the speaker outputs of an amplifier or receiver and a pair of speakers. UltraMatchrM is a method of matching the minimum output impedance of the amplifier or receiver, in addition to adjusting volume. It eliminates the need for a speaker selector or impedance matching equipment.

IMPORTANT- Before installation, review the manuals included with each component in your system. If you are unsure of any of the installation procedures described herein or elsewhere, consult a professional electronics installer.

特徵 Features

• Rotary control of volume level and speakers on/off

• IR receiver

• LED indicator for source component on/off status

• UltraMatch™ impedance matching

• Fits Standard and Decora@ faceplates

設置跳線阻抗匹配SET JUMPERS FOR IMPEDANCE MATCHING

重要提示：可以連接4歐姆的最小揚聲器負載每個Ultra Match™音量控制的輸出。

The jumper must be set in a position that correctly multiplies the impedance of the system to a level that is equal to or greater than the impedance of the amp.

1. Determine the amplifier's minimum impedance (as listed in its owner's manual or on its back panel).

2. Choose the correct impedance-matching chart (8 ohm or 4 ohm) shown on the reverse side of this page. If your amplifier is 6-ohm,

use the 8-ohm chart.

3. Determine the total number of 4-ohm pairs of speakers (rows on charts).

4. Determine the total number of 8-ohm pairs of speakers (columns on charts).

5. Look up your correct jumper setting and set the jumpers as shown in the circuit board illustrations on the reverse side of this page.
