The SPL SMC Surround Monitor Controller is an audiophile-grade speaker and source-management processor for 5.1 surround and stereo playback. Use it for surround and stereo production as well as postproduction for film and multimedia projects.
The device offers balanced connections over the built-in DB25 connector, and unbalanced connections over RCA connections. These connections are individuated for stereo and surround setups ”and you can switch between them at will.
The SMC offers controls not prevelant on your usual soundcard. With this device, you can adjust the levels of each output, fold L/R signal to mono, and fold Ls/Rs signals to mono. You can dim the signal by -20 dB, and you can mute all sound at any time. As the unit can manage several input sources at once, you can use it to compare and monitor material from multiple sources, without introducing extra AD/DA conversion stages.
Looks as Good as It Sounds
The SMC s steel-blue desktop enclosure with its slanted front panel is engineered to harmonize with the desktop production environment and can be placed exactly where control is needed due to its design and shape.
Stereo and Surround
In addition to a surround speaker set, a stereo pair can be connected to and managed by the SMC. A Sub-D input connector provides six surround and two stereo input channels. Eight additional RCA connectors allow easy connection of SACD, DVD, CD, or DAT players.
Multiple Connections
A passive through-output allows the stereo or surround input signal to be routed directly to a recording device. Volume control is handled by a discrete six-layer potentiometer and all switching functions by extremely durable precision pushbuttons.
Hardy Controls
The SMC Surround Monitor Controller has a large graded volume potentiometer on its face panel and has switching for Stereo Monitors, and seprate 5.1 Surround Monitors for L, C, R, LS, RS, and LFE. It also supplies switching for A/B/C/D Surround Sound, and L/R, LS/RS Mono switches. It has a -20 dB Mute and Mute All switches. The SRC is also known as the Model 2489 and is made in Germany.
