The combination of pear shaped pointer and conventional arc scale on translucent buff coloured dial results in an easily read meter, even when monitoring a row on a large console. The following comparison can be made based on a rise time to -3vu with steady deflection of 0vu:

For this reason the time to reach -3vu with a steady reading of reference deflection (0vu) has been taken as a more realistic measure. To specify the dynamic characteristics in terms of time to 99% of 0vu under such circumstances would give an unrepresentative measure of the speed of response.

The overswing, because damping is not so tightly controlled but allowed to spread within normal design restraints, can vary between deadbeat to 5%. The dynamic characteristics quoted, which requires the response time to 99% of reference deflection (0vu) to be 0.3 seconds +/-10% with an overswing of at least 1.0% but not more than 1.5% are not fully met. The performance of the meter is based upon the requirements of BS 6840: Part 17:1991, IEC 268 - 17: 1990. Calibrated for use with a 3.6k ohm resistor 4vu above the scale marking so that the reference deflection (0vu) is produced by a signal 4vu above 1mW in 600 ohms (1.228v). The standard scale is based on the VU A scale.Ī low range ac voltmeter suitable for connecting across a 600 ohm line and self contained except for requiring an external 3.6k ohm resistor. A white dial can be specified if required. Pointers and 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. Please refer to back page for full details. There is no calibration effect when mounted on a ferrous panel.Ī low range ac voltmeter offering a performance close to that of a full specification VU meter.

This rugged movement makes these meters equally suitable for portable or fixed audio applications.

Taut band core magnet movement incorporated as standard.

Constructed with gloss black phenolic moulded front with glass window and high impact translucent rear body moulding.

The meters offer a performance not significantly different from full specification VU meters to meet today's specific audio market requirement for both quality and distinctive retro styling at an affordable price. The AL20SQ Audio Level analogue panel meters complement the proven and popular Presentor series.
