Lyra Operation Manual - Test and Measurement - Prism Sound

Prism Sound LyraOperation ManualRevision 1.00All inputs have high-resolution peak metering, with overload indication 0.05dB below clipping; theanalogue input meters also have Overkiller-active indicators which light dynamically when theOverkillers are limiting.6.1.3 Outputs tabThe Outputs tab contains the controls and status indicators for all functions of the analogue outputsand S/PDIF outputs as described in the hardware section. In ADAT modes, the status of theADAT/SMUX outputs is also displayed here.Line output level is switched between +4dBu and -10dBV nominal by the '+4/-10' radio buttons.The stereo digital output has a versatile word-length control using TPDF dither or Prism Sound SNS(Super Noise Shaping), and the RCA connector can be switched to operate as either S/PDIF orAES3 as required. If the sample rate converter (SRC) is configured in the digital output, a separatesync source and sample rate can be selected.An assignable level control is available, for use as a monitor volume control, which can be assignedto any desired outputs using the row of 'VOL' buttons. The volume control can be adjusted using themouse, as well as with the front-panel knob. There is also a mute button (whose function is alsoavailable by pressing the volume knob on the Lyra front panel) and a numerical readout/setting box.Note that changes to the assignment of the level control can be prevented by engaging the lockbutton (marked with a key symbol) just above the level control. When engaged (red) the lock buttonprevents changes to the level control assignment in order to avoid accidental full-level output.Below each stereo output strip is a drop-list control allowing each output pair to be fed either directlyfrom the workstation ('DAW') or from a dedicated low-latency foldback mixer ('Mixer'), or from the© 2013 Prism Media Products Ltd1.38
