This controller hs been used in a post production studio and have been treated extremely well. It sounds amazing and is in excellent condition.
The SPL Surround Monitor Controller (SMC) is a one-point analog volume control and switching matrix for system-independent 5.1 surround and stereo monitoring for essentially any audio application:
Surround and stereo production
DVD-V, DVD-A, SACD and DTS authoring
Film and video postproduction
Video and game production
A/V and multimedia production
Audiophile home entertainment systems
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.
One of the SMC's biggest advantages is the possibility to manage several input sources, i. e. for comparing and monitoring SACD or DVD material.
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.
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.
