RDL AV INTERFACES - HALF-RACK Series

RDL's HR series are 'Half-Rack' Series products with an 'all-metal chassis' which may be used free-standing, using the feet supplied. Each unit may be labelled by removing an end cap and sliding out a clear plastic cover, which can be slid back in to cover user’s labelling, much in the manner of standard designation strips. Two units may be mounted side-by-side in an optional 1U 19-inch rack adapter.

A to D AND D to A CONVERTERS

These convert balanced and unbalanced analogue line-level inputs and outputs to and from standard digital audio signals operating at up to 24-bit resolution and 192kHz sampling.

HR-ADC1

HR-ADC1 - Analogue to Digital

This has a choice of balanced and unbalanced stereo audio line-level inputs which is then converted to either AES/EBU, coaxial S/PDIF or AES-3ID digital signals. Operating at up to 24-bits resolution and 192kHz sampling, either internally-generated or locked to an external source of sync, the HR-ADC1 offers 'superior analogue performance', 'very low distortion', 'exceedingly low noise' and 'remarkably flat frequency response'

The front panel has two rotary controls to set the audio input levels and an array of LEDs for monitoring level. Two rows of twelve LEDs indicate left and right peak or VU average audio levels. The 0dB reference level of the meters may be set to -14, -16, -18 or -20dBFS. Audio peaks between -10dBFS and 0dBFS clipping are displayed separately by two further rows of six LEDs to the right, which are also used as menu LEDs when programming the settings with two adjacent push buttons. The peak display may be set to either flash or store the peak values. Flash duration settings provide for instantaneous, 1/3 second hold or 2/3 second hold. If the peak display is set to 'store' then the highest peak recorded remains displayed until the 'peak reset' button is pushed. A column of six LEDs indicate the internal sample rate; three more the resolution in bits. These are set by two dedicated push buttons. Another button, with associated LED, enables external sync, with another LED indicating 'external sync lock'. A final button switches power, and is equipped with an LED indicator.

The rear offers three connectors each for left and right audio inputs. RCA (phono) sockets provide unbalanced connections whilst either 3-pole female XLR connectors or detachable terminal block connectors may be used for the balanced inputs, which may be wired unbalanced. The digital audio output has three connectors; a 3-pole male XLR provides the balanced AES/EBU output, RCA (phono) and BNC connectors provide the S/PDIF and AES3ID outputs respectively. A switch selects which is used. A similar array of three connectors provides the external sync input, with a female XLR used for the AES/EBU balanced input. The connector used is selected automatically. Both a co-axial connector and a detachable terminal block are provided for connecting power.

HR-DAC1

HR-DAC1 - Digital to Analogue

This offers a choice of AES/EBU, coaxial or 0ptical S/PDIF or AES-3ID inputs, which is converted to stereo audio using high speed delta-sigma conversion, digital filtering and filtered wideband analogue circuitry to drive both balanced and unbalanced outputs.

HR-DSX4

HR-DSX4 Digital Audio Selector

This offers a means to select one of four digital audio sources to one output. Each input may be fed through one of three jacks connectors, S/PDIF optical, S/PDIF (or AES-3ID) coaxial or AES/EBU. Solid-state switching is used to select one of the four inputs. Operating up to 24-bit resolution, 192kHz sampling-rate, the selected input is decoded, re-clocked and transmitted through the output. Switching may be controlled locally or remotely; a remote control output is available from the selected input. RDL's proprietary 'Sure-Lok' auto recovery supervision monitors possible causes of latch-up and re-initiates digital signal-lock, to provide 'highly stable operation in the variety of conditions encountered in professional environments'.

The front panel has a switch to select remote or local control with an LED to indicate the mode. Four large buttons select which of the input sources is fed to the output, each with an LED to show which input is in use. Upon selecting a source, the LED lights if a valid input is present; otherwise it flashes. If the button for a selected source is pushed again, all inputs are turned off. The power button has an associated LED to indicate power is present.

The rear has five groups of connectors for four inputs and the outputs Each group has RCA (phono), optical and XLR connectors for S/PDIF coaxial, S/PDIF optical and AES/EBU connection respectively. The output XLR is male and a switch selects the appropriate output connector and any required electrical and data format conversion. The inputs have female XLR inputs. Each group of connectors also has a three-pole detachable terminal connector for remote control. Both a co-axial connector and a detachable terminal block are provided for connecting power.

In the remote control mode, inputs are selected by an external switch or open-collector closure to ground, per source, which may be momentary or continuous. When a source is selected, the unit provides a 50mA open-collector output for the selected input to control other equipment or modules. The remote control terminals associated with the output connectors provides the facility to turn off all inputs.
