The Central Station features three sets of stereo analog inputs to switch between input sources such as: DAW, mixer, CD/DAT/Tapeplayer, or keyboards/samplers. Two stereo analog inputs feature TRS balanced and the third stereo input features RCA inputs with trim control for level matching of input signals. In addition, the Central Station will accommodate two digital inputs via S/PDIF or TOSLINK providing D/A conversion up to 24Bit/192kHz. This allows you to monitor DAW and CD/DAT outputs through the same professional quality converter for an accurate A/B comparison and high quality monitoring environment. The digital to analog converter offers the highest possible audio quality with over 117dB dynamic range and ultra high quality analog circuitry. The Central Station features three sets of monitor outputs, each with their own set of passive trim controls. The monitoring section also provides MUTE, DIM and MONO switches. In addition, the Central Station includes a set of CUE outputs that can feed headphone amplifiers and a separate stereo MAIN line level output. PASSIVE SIGNAL PATH The main audio path of the Central Station uses no amplifier stages including op amps or active IC's (integrated circuits) that add noise, color, distortion, ... Signal routing in the Central Station is acheived utilzing 34 sealed mechanical relays (instead of active IC's) maintaining a minimal signal path design wherein extraneous electronics are hard-wire bypassed. Using relays ensures the most transparent signal path maximizing dynamic range, frequency range, and headroom, while minimizing noise and coloration. The Central Station uses quality passive components including military grade 1% tolerance metal film resistors, multi-element potentiometers. METERING The Central Station features dual fast-acting 30-segment peak/hold LED's for accurate metering. The front panel of the Central Station includes both dBu and dBfs scale as well as peak/hold clear switch and meter alignment switch for addtional metering options. TALKBACK Central Station has an onboard TALKBACK microphone which is routed through the CUE outputs for communication between artist and engineer. The Central Station also includes a Microphone XLR input on the rear panel for use with an external microphone. When TALKBACK is used the CUE mix is automatically "dimmed" for added ease of communication. - Passive Audio Path - no op amps or IC's in main audio path - Five stereo inputs (2 digital and 3 analog) - 24-Bit/192kHz DAC (>117dB dynamic range) via SPDIF and TOSLINK - Three sets of monitor outputs; each with passive volume control - Talkback microphone with volume to feed headphone and cue output - Accurate dual 30-segment LED for metering - Two front panel headphone jacks with separate volume control - MAIN and CUE stereo output have independent input source - Optional console remote control with input, output, talkback, and volume Audio Inputs TRS1&2 Type ¼” TRS Passive-Balanced Input Impedance 2K-5K Ohm (Speaker load and Trim level dependent) S/N Ratio Greater than 140dB THD+N Less than .0005% (1KHz @ 0dBu) Frequency Response Greater than 1MHz AUX Type RCA Active-Unbalanced Input Impedance 8Kohm S/N Ratio Greater than 115dB (1KHz @ 0dBu, Unity gain) THD+N Less than .002% (1KHz @ 0dBu, Unity gain) Frequency Response 10Hz-50KHz, -.5dB Gain Range -90dB to +20dB S/PDIF Types RCA 75Ohm-coax and Toslink optical Dynamic Range 117dB THD+N 0.0025% (1KHz @ -1dBfs) Maximum output +18dBu (Active-Balanced) Sample Rates 44.1K, 48K, 88.2K, 96K, 176.4K, 192K Note: All Input specifications (except Input Impedance) measured at Speaker A output, Trim and Main Level set to maximum.
