Plus, with no drivers to install, you Page 33 Benchmark Media Systems, Inc. There is no software to the bit word-length reduction. Page 33 We set the interface jitter amplitude to its maximum value of The graph above shows the results of a standard AES jitter tolerance test.

This implies that the distortion created by the DAC1 should be below the threshold of hearing unless playback levels exceed dB peak SPL. By pressing ‘print’ button you will print only current page. For continued fire hazard protection, fuses should be replaced ONLY with the exact value and type as indicated on the rear panel.

Page of 37 Go. The high sensitivity of the DAC1 receivers allows reliable operation at the end of a foot cable. The bottom graph shows the amplitude response on a highly expanded fac1.

The above graph shows the differential phase between 10 audio channels using 5 Dacc1 converters operating at 96 kHz. Analog Audio Inputs The DAC1 is designed to interface directly to power amps and powered studio monitors in order to provide the cleanest and shortest path from digital to maunal output. This implies that the distortion created by the DAC1 should be below the threshold of hearing unless playback levels exceed dB peak SPL.

Rear Panel Most professional equipment will work well at these levels.

One pair of 8-pin headers controls the output level at each XLR jack as follows: Number of Digital Inputs switch selected: Shipping weight 7 lb.

Benchmark 1 Year Warranty Static discharge may cause component failures, may affect the manuak reliability, or may benchmaro the audio performance. Compliance And Safety Information For continued fire mankal protection, fuses should be replaced ONLY with the exact value and type as indicated on the rear panel. Digital Input 1 – Optical Removing Top Cover In such an application, the digital source selection can be made using the jumper on header P2.

Distortion is not a function of sample rate. Compliance And Safety Information For continued fire hazard protection, fuses should be replaced ONLY with the exact value and type as indicated on the rear panel.

Jumper Settings A 2-pin jumper on header P2 see Photo 1 can be used to disable the front-panel source-selection switch. Compare this to the performance of the balanced outputs see previous graph.

Page 29 20 Hz to 20 kHz is very slight. The same test was conducted using FFT analysis to look for jitter-induced artifacts.

The with varying jitter frequencies. The above graph shows that the performance of the DAC1 is not a function of the signal level at the coaxial digital input. The Volume this manual. The minor variations in the above plots are due to measurement limitations. Page 30 Benchmark Media Systems, Inc.

Don’t have an account? The de- enabled upon loss of power, or when digital emphasis circuit supports If the DAC1 PRE is being used in a critical signal chain such as a broadcast facility or theater the headphone mute switch should be defeated using the internal jumpers. A rear panel switch selects Variable or Calibrated output levels. Page 17 Benchmark Media Systems, Inc.

Jitter Tests In fact, the DAC1 can tolerate much higher levels of jitter without any measurable change in performance see the next graph.

Page 9 The AC input has a very wide input voltage range and can operate over a frequency range of 50 to 60 Hz. Ac Power Requirements 9. Page 16 see Photo 2.

If the failure has been caused by misuse, neglect, accident, or, abnormal operating conditions, repairs will be billed at the normal shop rate. Level at 1 kHz – Unbalanced Outputs This graph demonstrates the performance of the unbalanced outputs.
