A recorder standing upright, photographed slightly from the left against a grey ground: two white Otari NAB reels side by side at the top, the head block and tape path below them behind a hinged cover, a row of six small keys at the left of the deck, and across the lower panel a pair of large knobs, two lighted VU meters, four square function keys and a rotary control at the right, over a finned vent strip along the bottom edge.⤢ zoomA recorder standing upright, photographed slightly from the left against a grey ground: two white Otari NAB reels side by side at the top, the head block and tape path below them behind a hinged cover, a row of six small keys at the left of the deck, and across the lower panel a pair of large knobs, two lighted VU meters, four square function keys and a rotary control at the right, over a finned vent strip along the bottom edge.

Front elevation of the recorder standing upright, drawn as a fine grey line diagram: the two reel tables at the top with the tape path and head block between them, a row of transport and function keys across the middle, and two VU meters flanked by rotary controls below. It is dimensioned 16.93" (430mm) across the top and 20.67" (525mm) down the right-hand side.⤢ zoomFront elevation of the recorder standing upright, drawn as a fine grey line diagram: the two reel tables at the top with the tape path and head block between them, a row of transport and function keys across the middle, and two VU meters flanked by rotary controls below.

Side elevation of the same upright recorder as a fine grey line diagram: a tall rounded rectangle for the side panel with four fixing points, a rectangular recess at its centre, connectors standing out from the left-hand (rear) edge and a small fitting at the lower right, all on a base rail that overhangs the panel slightly. It is dimensioned 8.11" (206mm) across the top and 8.47" (215mm) across the base.⤢ zoomSide elevation of the same upright recorder as a fine grey line diagram: a tall rounded rectangle for the side panel with four fixing points, a rectangular recess at its centre, connectors standing out from the left-hand (rear) edge and a small fitting at the lower right, all on a base rail that overhangs the panel slightly.

A recorder built as a desk-top unit, seen from the front and a little to the left: a separate electronics panel with two rotary controls, two lighted VU meters and a further knob stands across the back on a raised bridge, the transport lies back below it with two white Otari NAB reels flat and the head block between them, and the whole sits in a plain wedge-shaped cabinet on small feet.⤢ zoomA recorder built as a desk-top unit, seen from the front and a little to the left: a separate electronics panel with two rotary controls, two lighted VU meters and a further knob stands across the back on a raised bridge, the transport lies back below it with two white Otari NAB reels flat and the head block between them, and the whole sits in a plain wedge-shaped cabinet on small feet.

Side elevation of the desk-top cabinet as a fine grey line diagram: a long wedge with a low rounded front edge at the left, rising to the raised rear section that carries the electronics panel at the right, with the head block and a guide standing proud of the sloping deck, and six fixing points along its side — four round ones set as two pairs on the sloping panel, and on the raised rear section a square one and a round one. The whole stands on two small feet. It is dimensioned 26.77" (680mm) across the top for the overall depth, 18.9" (480mm) down the right-hand side for the overall height, and 6.61" (168mm) at the left for the height of the low front edge.⤢ zoomSide elevation of the desk-top cabinet as a fine grey line diagram: a long wedge with a low rounded front edge at the left, rising to the raised rear section that carries the electronics panel at the right, with the head block and a guide standing proud of the sloping deck, and six fixing points along its side — four round ones set as two pairs on the sloping panel, and on the raised rear section a square one and a round one.

Front elevation of the desk-top cabinet as a fine grey line diagram, turned the right way up: the side panels rise as narrow rails at either edge and a plain panel fills the top of the cabinet. Below it the deck shows the two knurled reel hold-down knobs to left and right of a vertical tape-path detail, the head block with capstan and pinch roller beneath them, and a row of small keys and switches along the front. It is dimensioned 16.93" (430mm) across the foot.⤢ zoomFront elevation of the desk-top cabinet as a fine grey line diagram, turned the right way up: the side panels rise as narrow rails at either edge and a plain panel fills the top of the cabinet.
