<p><strong>OSD Audio SVC405 is a 300-Watt impedance-matching volume control with two-source switching control</strong> that allows you to adjust the volume of a pair of speakers independently of other speakers within a whole house audio system and includes an A/B switch that lets you add two sources and one pair of speakers or two pairs of speakers and one source. Ideal for both home and commercial installations, this decorative in-wall volume control includes an impedance-matching features so parallel connections of multiple volume controls can be installed without damaging expensive audio equipment.

Another option would be to connect two audio sources such as one amp and one receiver to play through one set of speakers and switch between the sources.</p> <p><strong>Specifications</strong></p> <ul> <li>Impedance matching volume controller with A/B switch</li> <li>Power handling: 300W per channel</li> <li>RMS Rating: 100W</li> <li>Frequency Response 20Hz - 20kHz</li> <li>Front-mounted switch allows for easy adjustment when multiple pairs of speakers are connect to a single receiver or amplifier</li> <li>Impedance matching up to 8 pairs of speakers</li> <li>Steps: 12 (make before break)</li> <li>Total Attenuation: 42 dB (Max)</li> <li>Includes White, Ivory and Almond Plates, Inserts and Knobs</li> <li>Fit in single gang box</li> <li>5-yr warranty</li> </ul>
