Model 2489
One-point stereo and 5.1 volume control, source and speaker management

"But the best part about the SMC was its sound, or rather lack of sound." (MIX Magazine, US)

Detailed Description

Designed to provide only the necessary functions with excellent audio quality, the SMC offers a uniquely cost-effective speaker and source management solution.

Users & Applications
The advantages of the SMC become especially apparent in combination with modern audio and video production tools such as ProTools™, Nuendo™, Cubase™, Logic™, Deck™ etc. Monitor levels and source management can be handled independently of the software and with virtually no loss in quality. You no longer need to set up additional aux sends or an alternative surround master for monitoring. In addition, you won't have to worry about over- or underdriving the converters due to monitor levels.

One of the SMC's biggest advantages is the possibility to manage several input sources: comparing and monitoring SACD or DVD material is much easier than having to import all of your audio files and set up monitor mixes – not to mention the conversion of multichannel audio.

Standard A/V receivers are often used for this task. The problem with this is that the audio has to be either AD/DA converted or manipulated by signal-degenerating control circuitry (VCA's, DAC's etc.) for volume control, so you never hear the unadulterated audio – especially frustrating when you're working on SACD or DVD-A projects.

The SMC's rugged and ergonomic steel-blue desktop enclosure with its slanted front panel harmonizes perfectly with the desktop production environment and can be placed exactly where control is needed.

Rear Panel & Connections
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. A slave 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.

SPL's renowned electronic balancing circuitry forms the basis for the SMC's I/O architecture. Its extended frequency range up to 100 kHz, exceptional dynamic spectrum and excellent common mode rejection ensure specs that exceed SACD standards, as only highest quality analog circuitry can provide.
