Presentor - AL 音频级模拟面板仪表

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.

模拟面板仪表的Presentor音频级范围补充了已验证和流行的工业和快速响应系列。该系列产品有三种型号，每款有四种型号，其性能与全规格的vu电表没有明显区别，以满足当今市场对物美价廉的需求。

• 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

选择四个款式,每个可用在三个尺寸

简单面板装配

面板装配伴随边框

前面板装配较低的面具

前面板与完整的边框

采用透明半透明的丙烯酸前和高影响后的身体造型。面具和面板，用黑色ABS塑形。

紧带磁铁运动中心将作为标准26毫米直径。当安装在有色金属板上时，没有校准效果。

崎岖的运动使米同样适用于便携式或固定的应用程序

Presentor AL – Specification

Presentor AL -规范

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.

一种低量程交流电压表，其性能接近于规格的vu表。适用于连接600欧姆线和自我控制，除非需要外部3k6电阻。在刻度标记上使用3k6欧姆电阻4vu进行校准，这样参考偏差(0vu)是在600ohms (1.228V)的1mW以上信号4vu产生的。

仪表的性能基于IEC 268-17的要求。

下面的响应曲线给出了与典型AL19、AL29和AL39米的全规格vu表的比较。由于阻尼不是在每个铝表上单独调整，而是允许在正常的工艺参数中下降，所以在0到5%之间波动的变化是可以发生的。

Pointer & Dials

指针与刻度盘

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.

即使在大型控制台上监控一排的时候，在半透明的浅黄色表盘上的管状指针和平坦的圆弧刻度的组合，也能很容易地读到表。如果需要，可以一个白色刻度盘。标准尺度是基于vu ' A ' scale，但也可用' B '规模。

Zero Adjuster

零位调整装置

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.

通常定位在表面安装样式(M和B类型)和后面的面板样式(W和WF类型)后面。可以其他选项。
