AL20

The Vintage AL20 is an Audio Level meter in the Type 20 body style. It has a circular 55.6 mm diameter bezel and is suitable for rear panel clamp mounting.

The AL20 is a low-range AC voltmeter designed for VU audio level indication. It is suitable for connection across a 600 ohm line and requires an external 3.6k ohm resistor. It is calibrated so that the 0 VU reference deflection is produced by a signal 4 VU above 1 mW in 600 ohms, equivalent to 1.228 V.

The Vintage analogue meter range was introduced by Sifam for applications requiring a more traditional, classically styled meter, as commonly seen on traditional consoles, rack-mounted units and panel-mounted equipment.

The range combines distinctive retro styling with contemporary construction and is designed to provide high performance at an affordable price. Vintage meters complement the proven Presentor series and are available in Industrial, Audio Level and Fast Response versions.

The range is available in four body styles: Type 15, Type 19, Type 20 and Type 20SQ. Depending on the model, options include AC and DC industrial ranges, Audio Level meters with VU scales and Fast Response meters with PPM scales.

All Vintage meters use a taut band core magnet movement as standard. The movement is suitable for portable or fixed applications and has no calibration effect when mounted on a ferrous panel. Stronger suspension options are available for Industrial versions.

Illumination options are available across the range, including internal LED illumination on selected models and rear festoon illumination on Type 20 and Type 20SQ versions.

Operating temperature: -25°C to +55°C
