PreSonus Central Station PLUS Monitor Controller

The PreSonus Central Station PLUS provides the perfect combination of stereo inputs, outputs, and recording-communication functions, allowing you to easily manage multiple sources and monitor speakers. With Central Station, you can easily switch between three sets of stereo, analog input sources. Two stereo S/PDIF digital sources connect via one coax and one Toslink optical port. You can audition these sources with up to three pairs of speakers, with individual trim pots for each speaker-recessed to avoid accidents.

You also get a pair of line-level main outputs, a pair of line-level cue outputs, and two screaming-loud headphone amplifiers with individual level controls. And because Central Station is a 1U rack-mount device, with only one multi-conductor cable running to the remote control on your desktop, all of the cabling is in the back of your rack, where it belongs.

High-End Audio Quality
The pros know that for critical listening, a monitor-control system must be as sonically transparent as possible. That’s why PreSonus gave the Central Station an audiophile-quality, passive signal path, with no op-amps or ICs, and equipped the S/PDIF inputs with high-definition, 24-bit, 192 kHz D/A converters.

The Meters
To enable you to watch your input levels, the Central Station sports dual 30-segment, tri-colored, fast-acting, peak-hold LED meters, which can display dBu and dBfs. A handy Clear switch lets you clear the peak-hold.

A Complete Tool Set
Because PreSonus Central Station PLUS is a professional tool, PreSonus included all of the key features you’ll need to manage monitors in a commercial or project studio. Speak to the musicians over the headphone and cue buses using the onboard talkback microphone or connect a dynamic mic to the XLR talkback input.

The cue signal is automatically dimmed when you use the talkback mic, and a jack admits a footswitch for hands-free talkback operation. A Mono switch sums the stereo source so you can check for phase problems, and a Dim switch lets you reduce the speaker output by 16dB. Of course, you can mute the speakers as well.

CSR-1 Remote
The CSR-1 provides remote control of volume for each input pair and for the talkback mic, as well as controlling muting, input-source switching (TRS1, TRS2, Aux, and S/PDIF), and passive speaker-output switching (stereo pairs A, B, and C). An Active light illuminates when the CSR-1 is controlling main volume. The Dim and Mono features also can be controlled from the remote unit.

A built-in electret condenser talkback mic with momentary on/off Talk button enables you to address the musicians through their headphones. (The Central Station main unit also has a talkback mic, so make sure to turn down whichever talkback mic you aren’t using!)

Central Station connects to the CSR-1 via a proprietary DB15 cable (included), enabling you to keep the Central Station in your rack and control it from your desktop. This provides maximum convenience with minimum wiring, keeping your workspace free of cable clutter.
