2. Đặc điểm Bộ tiền khuếch đại Preamplifier Manley ELOP®+ STEREO LIMITER COMPRESSOR:

The original Stereo ELOP^®, or Electro Optical Limiter, was one of the first Manley products from the early 1990’s. With its through-hole printed circuit board construction and hours of tedious hand-looming, it sure looked like 1992 inside the chassis.

The unit was scrubbed for buildability, embracing modern production techniques. Importantly, the power supply was upgraded to Manley's proprietary MANLEY POWER^™ universal voltage Switch Mode Power Supply, which lowered the noise level and made the unit a true world-traveler.

We've also added a 3:1 compression ratio feature which opens up the doors to greater versatility, especially for 2-buss applications. With careful reference to our sonic past, we have deployed our highest performance vacuum tube line amplifier and White Follower output stage in this new version, all housed in a build-efficient chassis behind a drop-dead gorgeous precision-CNC-milled faceplate - all proudly made in America, of course. The new Manley ELOP+ is everything you love about our legendary ELOP, plus!

1. GAIN CONTROL. Available on L and R channels. Adjusts the gain of the audio channel, with unity at about the 7th marking (1 o'clock). Limiting usually requires some make-up gain to compare IN / BYPASS. The Gain control can also be used as the level to tape.

2. REDUCTION CONTROL. Available on L and R channels. Reduction adjusts the amount of limiting or compression in that channel. This could also be called "threshold". Turning this control clockwise increases the amount of limiting or compression.

3. VU METER. One for each channel, showing the gain reduction in dB when switch #7 is deselected, and showing output level in dB when switch #7 is engaged and illuminated.

4. HP SC CONTROL. Inserts a high-pass filter into the sidechain circuit, reducing the amount of compression or limiting below 80 Hz. Note: this filter is changeable to 150 Hz via an internal jumper. See the manual for details.

5. IN / BYPASS CONTROL. If the switch is engaged & illuminated, audio will pass through the limiter / compressor circuit and all front panel controls will function. If the switch is disengaged, audio still flows through the tubes in the unit, but at Unity Gain with no compression or limiting.

6. COMPRESS / LIMIT CONTROL. This switch allows the ELOP+ to use two different compression ratios. Offering either compression at approximately 3:1 when the switch is engaged and illuminated, or limiting at approximately 10:1 when the switch is disengaged.

7. METER SELECT. Allows the user to monitor either Gain Reduction (switch engaged & illuminated) or Output of the unit (switch disengaged).

8. POWER SWITCH. Glows a soft amber color when an IEC power lead is connected to the unit. This indicates that the ELOP+ is in STANDBY mode. Engaging the switch takes the ELOP+ out of standby mode and into warm-up mode (flashing VU meters, brighter amber switch). This lasts 30 seconds, after which the MUTE relays will lift and the VU meters will stop flashing.

9. LINK / STEREO FUNCTION. When the LINK switch is engaged and illuminated, the ELOP+ applies the same amount of gain reduction to both the L and R channels. This is done to prevent image shifting that can occur if each channel is compressed individually. We suggest that when in LINK mode both channels have controls set the same. Please see the ELOP+ manual (below) for more details.
