Pin 1 chassis ground, pins 2 and 3 transformer balanced and floating, 110Ω impedance. Stereo per AES3 standard, 24 bit resolution, software processing selection of mono from left, mono from mono from sum.ģ2, 44.1, 48, 88.2 or 96 kHz, automatically selected. Software adjustable from -30.0 dBFS to -10 dBFS (VU) / -23.0 dBFS to -3.0 dBFS (PPM) Pin 1 chassis ground, Pins 2 (+) and 3 electronically balanced, floating and symmetrical. ≤ 0.01% THD (Bypass mode, de-emphasized) 20 Hz - 9.5 kHz bandwidth. ≥ 90 dB unweighted (Bypass mode, de-emphasized, 20 Hz - 9.5 kHz bandwidth, referenced to 100% modulation). Termination not required or recommended.Īdjustable from -6 dBu to +20 dBu peak, into 600Ω or greater load, software-adjustable. The user can specify the output load in software to calibrate the output level accurately into a bridging or 600Ω load.Ħ00Ω or greater, balanced or unbalanced. The two outputs have independent level controls.ģ51Ω (includes the third-order output EMI suppression network), electronically balanced and floating. Two monophonic outputs, capable to driving two transmitters. RFI filtered, with high-pass filter at 0.15 Hz (-3 dB). Converter outputs 64 kHz sample rate, which the 9300 then decimates to 32 kHz in DSP using an ultra-high-quality image-free synchronous sample rate converter. Pin 1 chassis ground, Pins 2 (+) and 3 electronically balanced, floating and symmetrical.Ģ4 bit 128x oversampled delta sigma converter with linear-phase anti-aliasing filter. Through-hole pads are available on I/O module for user installed 600Ohm termination. Stereo (Configurable to drive the processing selection with mono from left, mono from right, or mono from sum).ġ0kΩ load impedance, electronically balanced. Lowpass filter shape is parametric and can be set to be –0.1, –3, or –6 dB down at the cutoff frequency.Ĭonstrained by user settable fifth-order “quasi-elliptical” highpass filter to 50, 60, 70, 80, 90, or 100 Hz. All filters have equal-ripple (Chebychev-like) passbands and a 25 Hz notch for transmitter protection. Unit can be set up to comply easily with ITU-R and NRSC spectrum masks. The 9300 is a “multirate” system, using internal rates from 32 kHz to 128 kHz as appropriate for the processing being performed. The processing employs phase rotation to maximize loudness. Therefore, the polarity is frequency-dependent. Total System Distortion (De-Emphasized, 100% Modulation): The dynamic range of the A/D Converter, which has a specified overload-to–noise ratio of 110 dB, primarily governs it. The dynamic range of the digital signal processing is 144 dB. Output noise floor will depend upon how much gain the processor is set for (Limit Drive, AGC Drive, Two-Band Drive, and/or Multiband Drive), gating level, equalization, noise reduction, etc. ☐.2 dB, 50 Hz–9.5 kHz, or as determined by user-settable high-pass and low-pass filters. Certain specifications are presented here to assure the engineer that they are reasonable, to help plan the installation, and make certain comparisons with other processing equipment.Įxcept as noted, specifications apply for measurements from the analog left/right input to the analog #1 and analog #2 output. Therefore, the only way to evaluate the sound of an audio processor meaningfully is by subjective listening tests. It is impossible to characterize the listening quality of even the simplest limiter or compressor based on specifications, because such specifications cannot adequately describe the crucial dynamic processes that occur under program conditions.
