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.
模擬面板儀表的Presentor音頻級范圍補充了已驗證和流行的工業和快速響應系列。該系列產品有三種型號，每款有四種型號，其性能與全規格的vu電表沒有明顯區別，以滿足當今市場對物美價廉的需求。
- 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

Presentor AL – Specification
Presentor AL -規范
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.
一種低量程交流電壓表，其性能接近于規格的vu表。適用于連接600歐姆線和自我控制，除非需要外部3k6電阻。在刻度標記上使用3k6歐姆電阻4vu進行校準，這樣參考偏差(0vu)是在600ohms (1.228V)的1mW以上信號4vu產生的。
儀表的性能基于IEC 268-17的要求。
下面的響應曲線給出了與典型AL19、AL29和AL39米的全規格vu表的比較。由于阻尼不是在每個鋁表上單獨調整，而是允許在正常的工藝參數中下降，所以在0到5%之間波動的變化是可以發生的。
Pointer & Dials
指針與刻度盤
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.
即使在大型控制臺上監控一排的時候，在半透明的淺黃色表盤上的管狀指針和平坦的圓弧刻度的組合，也能很容易地讀到表。如果需要，可以一個白色刻度盤。標準尺度是基于vu ' A ' scale，但也可用' B '規模。
Zero Adjuster
零位調整裝置
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.
通常定位在表面安裝樣式(M和B類型)和后面的面板樣式(W和WF類型)后面。可以其他選項。
