6x4 Zone Processor with Tamper-Proof Front Panel 4 Mic/Line The ZonePRO 641m offers fixed I/O, pre-configured architecture, configurable insert processing and optional duplication of audio channels to another ZonePRO device via a link bus. The 641m features a total of six inputs and four outputs. Inputs include four balanced mic/line switchable terminal block inputs and two mono-summed pairs of unbalanced RCA inputs. Hardware-controlled microphone gain allows adjustment of microphone gain per channel. The 641m device has a pre-configured architecture with input processing, a central matrix and output processing. Two input insert positions and one output insert position allow channel-specific insert processing to be configured. AutoWarmth, a psychoacoustic function that maintains full frequency bandwidth even when the signal level has dropped, is permanently available on each output zone. A link bus allows duplication of the first six audio channels to another ZonePRO device in applications where additional output zones are required. The front panel of the 641m features a power status LED, a network traffic LED, and an RS-232 control port. Additional system control is offered in the form of optional Zone Controllers. This collection of hardware wall-controllers represents a series of simple, elegant user interfaces for functions such as volume, source and preset control. All ZonePRO devices can be controlled by third party control systems via RS-232 or Ethernet as applicable (see table for further information). ZonePRO Designer-the configuration, control and monitoring software for the ZonePRO family of devices-offers control of the ZonePRO 641m via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 641m.Features: 6 Inputs / 4 Outputs 4 Balanced Mic/Line Inputs 2 Unbalanced, Mono-Summed RCA Input Pairs Microphone Gain per Channel Pre-Configured Architecture Two Configurable Input Insert Positions One Configurable Output Insert Position AutoWarmth per Output Zone Link Bus Optional ZC Controllers Ethernet Control Serial Control Third Party Control Wizard-Driven Configuration Specifications: Indicators: Network Traffic, Power Input: 6 Total (4) Switchable Mic or Line, (2) Unbalanced, Mono-Summed RCA Input Pairs Input Connectors: Euroblock (Line and Mic) RCA (Source) Input Type: Electronically balanced/RF-filtered Input Impedance: Euroblock: >50kΩ Balanced, >25kΩ Unbalanced, RF Filtered; RCA: >25kΩ Unbalanced, RF Filtered Max Input: +20dBu Mic/Line, +12dBu RCA CMRR: >40dB, typically >55dB @ 1 kHz Mic Preamp gain: 30 to 60dB Mic Preamp Equivalent Input Noise (EIN): < -118dBu, 22Hz-22kHz, 150Ω Source Impedance Mic Preamp Phantom Power: +15VDC Output: 4 total Output Connectors: Euroblock Output Type: Electronically Balanced, RF Filtered Output Impedance: 120Ω Balanced, 60Ω Unbalanced Max Output: +20dBu A/D Converter: dbx Type IV conversion system A/D Dynamic Range: (line) >113 dB, A-weighted, >110 dB unweighted Type IV Dynamic Range: >119dB, A-weighted, 22kHz; BW: >117dB, unweighted, 22kHz BW Digital Output Dynamic Range: >114 dB A-weighted, 110dB unweighted Sample Rate: 48kHz D/A Dynamic Range: 112 dB A-weighted, 109dB unweighted, 22kHz BW Dynamic Range: >109 dB A-weighted, >106 dB unweighted, 22kHz BW THD+Noise: 0.003% typical at +4dBu, 1kHz, 0dB gain Frequency Response: 20Hz - 20kHz, +/-0.5dB Interchannel Crosstalk: >80dB typical Propagation Delay: 0.6 msec Operating Voltage: 100VAC 50/60Hz, 120VAC 60Hz and 230VAC 50/60Hz Power Consumption: 29 W BTU:
