The Presentor Audio Level range ofanalogue panel meters complements the proven and popular Industrial and Fast Response series. The range is available in threesizes each in four styles and offers a performance not significantly differentfrom full specification vu meters to meet today’s audio market requirement forquality 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 aperformance close to that of a full specification vu meter. Suitable forconnecting across a 600 ohm line and self contained except for requiring anexternal 3k6 resistor. Calibrated for use with a 3k6 ohm resistor 4vu above thescale marking so that the reference deflection (0vu) is produced by a signal4vu 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 meterwith that of typical AL19, AL29 and AL39 meters. A variation in over swingbetween 0 and 5% can occur since the damping is not individually adjusted oneach 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 andflattened arc scale on translucent buff coloured dial results in an easily readmeter, even when monitoring a row on a large console. A white dial can bespecified 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 ofsurface 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。
