没有扫描仪无法上图。谢谢leslie兄。
该款未在国内销售过虽只有70W/8欧，因其大电流设计，推力比KRELL（100W）还好，音色既有英国声的特点，有开扬大气，分析力俱佳。

前级型号是???
后级The Exposure 4 Power Amplifiers
The Exposure 4 is the top of the range series of power amplifiers and comes in two forms, the Single 4 and the Dual 4 Regulated, both of which offer state of the art performance.
The Single 4 Power Amplifier
This power amplifier is available either with or without an internal regulated +/-24v pre-amplifier supply and as such represents a very flexible unit. As with all Exposure power amplifiers it uses the same circuit technology, but with an improved power supply section. In this case it is based on a custom made mains transformer of 325VA which is split into two windings one of 245VA used for the power amplifier section with the remaining 80VA being used for the optional pre-amplifier supply. The transformer, whilst being of the same overall VA rating produces more current (A) than the one used in the 8. Additionally a higher voltage rail is available on the board due to the larger custom designed power supply capacitors. Each channel is also individually rectified in order to maintain a high channel separation. It has a nominal output of 70 Watts into 8 Ohms and a transient capability of 250VA.

The Exposure 7 Pre-Amplifier
This audio pre-amplifier of exceptional sound quality is designed for zero crosstalk between channels. When used in its dual form with the Exposure 9 professional monitor pre-amp supply and Exposure dual 4 regulated power amplifier, the ultimate goal of total channel separation throughout the amplification chain is achieved. This has the obvious benefits of preserving the stereo information as it was originally recorded. Exposure produce the only range of amplifiers that currently offer this most obvious of advantages.
There are two types of 7 pre-amplifier available, the "Single type" and the "Dual type". The only difference is in the number of power supplies required to make the pre-amp operative. An additional DC lead is required for the dual type and a single type may be "upgraded" to a dual type when improving a system. This can either be carried out by your dealer or by returning the pre-amplifier to the factory. The "gram" input is selectable for moving magnet and moving coil cartridges by a switch on the rear panel and has a two stage passive RIAA equalisation circuit for greater accuracy and headroom. Each channel of the pre-amplifier is on a separate board for total channel separation but are linked for power supply purposes in the "single" type. There are no "plug in" boards as these can vibrate in use and after a period of time result in improper and dirty contacts and so degrade sound quality and reliability.
top
The two high level line inputs are taken directly from the input sockets on the rear panel to the high quality selector switch and then on to the board, so that they do not interfere with the gram input. There is no tape monitor circuit available as this would involve putting a switch between the main output of the pre-amp and the power amplifier. This clearly would degrade the performance, however if this function is desperately needed it can be created by the use of the "EXPANDER" being inserted between the pre & power amplifier.
The Exposure 7 pre-amplifier whilst being internally regulated requires an external +/- 24V regulated power source. This can be either from one of the two power amplifiers, which offer internal pre-amplifier supplies, or for greatly improved performance one of the two types of Exposure stand alone supplies can be used. For complete independence of channels you will need to use at least 2 x 6 mains power supplies or the 9 professional monitor supply.
Both gram inputs and the main output utilise the same custom made gold plated phono sockets found on the power amplifiers. This provides the correct electro-mechanical link created when the supplied phono-phono lead is used to connect the two units together. Other types of phono-phono lead will create a frequency imbalance and cause a rise in distortion which will adversely affect the attainable performance.

该款未在国内销售过虽只有70W/8欧，因其大电流设计，推力比KRELL（100W）还好，音色既有英国声的特点，有开扬大气，分析力俱佳。 |
上图还要用扫描仪吗？我想没这必要吧？用数码相机拍一下就可以了啊～～ 网上交易我想肯定是要看一下实物图的，你说是吗？
