Owner’s Manual Getting Started INTRODUCTION Overview Thank you for purchasing the Central Station Plus, the ultimate monitoring and communications system for recording studios. The Central Station uses highgrade components to ensure optimum performance that will last a lifetime and features a purely passive signal path for ultimate sonic performance.
1 1.1 1.0 Getting Getting Started Started 1.1 Central Station Plus Getting Started Connect Power Getting Started Connect Power Before connecting a power supply to the Central Station, ensure that the power supply meets the input-voltage requirements of the region or country where you are using it. PreSonus only supports the power supply that is shipped with your Central Station.
Owner’s Manual 1.3 Getting Started Connecting the CSR-1 to your Central Station 1 1.3 Connecting the CSR-1 to your Central Station Getting Getting Started Started 1. Connect one side of the included DB15 cable to the back of the CSR-1 and the other side to the Console connection on the back of your Central Station. Please note that the DB15 cable has a proprietary pin-out; it looks like a standard VGA cable but is wired differently.
1 1.5 Central Station Plus Getting Started Using the Digital Input 10. Power up your power amp or powered monitors and turn the level controls to 0 dB. Getting Getting Started Started 11. Press the Speaker Output A button. 12. Press the TRS 1 button in the Main Input Select section. 13. Play a stereo signal from your main input source and slowly turn the volume on the source to unity gain. You may need to consult the manufacturer of your main input source if you do not know the position of unity gain.
Owner’s Manual 1 1.6 Using the Headphones and Talkback System Getting Getting Started Started 1. Turn the Phones and Mic levels fully counterclockwise. 2. Press the Phones 1 control knob so that the Cue light, rather than the Main light, is illuminated. 3. Press the TRS 1 button in the Cue Input Select section. 4. Connect a pair of headphones to the Phones 1 output. 5. Play a stereo signal from the source connected to the TRS 1 input. Overview Overview 6.

Owner’s Manual 2 2.2 Features The Central Station features high-quality analog circuitry and digital conversion. Three sets of stereo analog inputs enable the Central Station to accept a wide variety of sources. Its S/PDIF coax and Toslink (optical) digital inputs provide up to 24-bit, 192 kHz digital-to-analog conversion, and the converters deliver over 115 dB of dynamic range. Each of the three sets of balance monitor outputs has a passive trim pot.
3 3.1 Central Station Plus Calibration Calibrating the Meter 3.0 Calibrating Your Central Station Getting Started In order to create the most accurate mixing environment, it is important to calibrate each component in your system so that the metering and output levels match. 3.1 Calibrating the Meter The meters on your Central Station can (and should) be calibrated to match the meters in your DAW or on your mixer. Overview 1.
Owner’s Manual Calibration Calibrating Speaker Levels 3 3.3 Getting Started it is set at its optimum or maximum level. Instead, turn on your phono preamp (if necessary) and increase the Aux Input Level knob, starting from -80, until the red 0 dBVU meter just comes on (and no higher). 5. Repeat steps 1 through 3 for the secondary/cue audio sources connected to the TRS 2 and Aux inputs.
3 3.3 Calibration Calibrating Speaker Levels 3.3.1 Central Station Plus Maximum Loudness Reference Getting Started This method of speaker calibration references a 0 dBVU meter reading to the loudest level you want.
Owner’s Manual Calibration Calibrating Speaker Levels 3 3.3 NOTE: dBFS means “decibels full scale” and is associated with decibel amplitude levels in digital systems where there is a finite maximum available level (such as in standard PCM encoding). The maximum level possible is referred to as “0 dBFS.
3 3.3 Calibration Calibrating Speaker Levels Central Station Plus Getting Started 10. If you are calibrating a monitoring system with independent subwoofer level control (such as a 2.1 or 2-way speaker system), repeat steps 4 to 9 for the subwoofer level. Repeat steps 1 through 10 for the monitoring systems connected to Speaker Outputs B and C. 11. Test: Play audio through Speaker A only. Without adjusting any of the Central Station’s levels, toggle Speaker A off and Speaker B on.
Owner’s Manual 4 4.1 Getting Started Sample Hookup Diagrams The Central Station is an extremely flexible tool and can be used in all stages of the recording and music-production process. There are many ways to use and set up your Central Station. Here are two typical setups.

The built-in talkback microphone is an electret condenser microphone and is positioned just below the Talkback Level knob. •• Talkback Level. Adjusts the gain level of the talkback microphone preamplifier +15 to +55 dB. •• Talk.
Owner’s Manual 5.1.3 Controls and Connections Front Panel Layout 5 5.1 Cue/Main Select Overview Getting Started The Central Station comes equipped with separate Cue and Main signal paths. The Cue signal path includes the talkback-microphone signal and sends this signal to the recording artist via an external headphone amp or the two onboard headphone amps. The Main signal path is intended for the control room and does not include the Talkback signal. •• Cue Output Level Control.
5 5.2 Central Station Plus Controls and Connections Back Panel Layout 5.1.5 Passive Speaker Control Getting Started Speaker Select (A, B, and C). These buttons activate stereo speaker linelevel outputs A, B, or C. Speaker Select A and B cannot be enabled at the same time. Speaker Select C can be enabled concurrently with either A or B. Because of this, Speaker C is typically used for a subwoofer. •• Speaker Trim Left/Right (A, B, and C).
Owner’s Manual 5 5.2 Digital Inputs (24-bit/192 kHz) Getting Started 5.2.2 Controls and Connections Back Panel Layout Central Station automatically reads and locks to the sample rate of the incoming digital stream and can receive and lock to sample rates of 44.1, 48, 96, and 192 kHz. Both of these digital inputs are designed for the S/PDIF stereo digital format. Overview Coaxial connectors are most commonly used for S/PDIF.
5 5.2 Central Station Plus Controls and Connections Back Panel Layout 5.2.5 Analog Inputs Getting Started These inputs are for your audio sources (mixer, audio interface, CD player, etc.). Only balanced cables should be used when connecting the balanced TRS inputs of your Central Station to these devices. Because of the Central Station’s passive circuitry, using unbalanced cables can reduce the output level and can introduce noise into your system. •• TRS 1 (L/R).
Owner’s Manual 5.3 Controls and Connections Central Station Remote 5 5.3 CSR-1: Central Station Remote Getting Started The Central Station Remote Control (CSR-1) connects to the rear of the Central Station via a proprietary DB15 cable (included with the Central Station Plus) to control Volume, Talkback, Mute, Input Source Switching and Speaker Output Switching functions.
