Presentor - AL

The Presentor Audio Level range of analogue panel meters complements the proven and popular Industrial and Fast Response series. The range is available in three sizes each in four styles and offers a performance not significantly different from full specification vu meters to meet today’s audio market requirement for quality at affordable prices.

Choices of four styles, each available in three sizes
Simple back of panel mounting
Back of panel mounting with accompanying bezel
Front of panel mounting with lower mask
Front of panel with full bezel
Constructed with transparent acrylic front and high impact translucent rear body moulding. Masks and bezels, moulded in black ABS
Taut band centre magnet movement incorporated as standard with 26mm diameter barrel. There is no calibration effect when mounted on a ferrous panel.
The rugged movement makes the meters equally suitable for portable or fixed applications

Presentor AL - Specification

A low range ac voltmeter offering a performance close to that of a full specification vu meter. Suitable for connecting across a 600 ohm line and self contained except for requiring an external 3k6 resistor. Calibrated for use with a 3k6 ohm resistor 4vu above the scale marking so that the reference deflection (0vu) is produced by a signal 4vu above 1mW in 600ohms (1.228V).
The performance of the meter is based upon the requirements IEC 268-17.
The response curves below give a comparison of the full specification vu meter with that of typical AL19, AL29 and AL39 meters. A variation in over swing between 0 and 5% can occur since the damping is not individually adjusted on each AL meter but allowed to fall within normal process parameters.

Pointer & Dials

The combination of tube pointer and flattened arc scale on translucent buff coloured dial results in an easily read meter, even when monitoring a row on a large console. A white dial can be specified if required. The standard scale is based on the vu ‘A’ scale but the ‘B’ scale is also available.

Zero Adjuster

Normally positioned on the front of surface mounted styles (M and B types) and on the rear of behind panel styles (W and WF types). Other options may be specified.

Operating Temperature

-25°C to +55°C

Illumination

Comprehensive options are available.

Overhead - available for W and WF styles. Using 6mm festoon style lamp.
Light box - available for all styles for types 29 and 39. Using either festoon or T13⁄4 flanged lamps.
LED Illumination - internal LED illumination is also available for all sizes and types.
