With a single stereo line-level input and stereo loudspeaker outputs these can be driven from a mixer, pre-amplifier or directly from a recorder or PC sound card. A single volume control on the front panel adjusts level. A range of mounting accessories is available for the Radio Design Labs EZ-series.
The EZ-Series offers a wide range of stand-alone designs including distribution amplifiers for line level audio, headphones, composite and XGA/XGA video, audio pre-power and mixer amplifiers, AV input selectors and computer video selectors. All models may be connected and operated without the use of tools, using standard cables. They are housed in enclosures with the same height, with widths in increments of one sixth of a rack-width, so they may be mounted singly or in multiples in a range of accessory mounts. Audio and video are switched using solid-state circuitry to avoid degradation due to dirty switches; critical connectors are gold-plated for reliable connections. All use 24 volt power, supplied from external AC adapters.
The front panel has a single rotary level control. LED indicators show when power is connected and when the overload protection is active. The rear panel has a locking co-axial connector for the power inlet, two pairs of sprung wire terminals for left and right loudspeaker outputs and a switch to select either 8 ohm or 4 ohms speaker impedance. Two pairs of RCA(phono) sockets provide the stereo line inputs. A switch selects stereo or mono operation.
