Fibre or plastic washers may be used to prevent the front panel becoming marked by the mounting bolts. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. The signal on the channel set to dB will most likely control the stereo side chain all of the time.

Drawmer DL251 Stereo Spectral Audio Compressor Limiter Enhancer

The use of this facility and extensive enhancement could be counter productive, so some moderation is advised. A typical example is a hi-hat sound occurring at the same time as a bass drum beat; as the compressor pulls dramwer the gain in response to the bass drum level, the hi-hat will be reduced in level by a corresponding amount. Will usually ship within 3 business days of receiving cleared payment – opens in a new window or tab. If the rear panel Link button is set to Peak, then the gain reduction is controlled by the peak level of whichever channel is loudest at any time.

Any poor wire terminations or jack socket closing contacts in the side chain jack wiring will certainly cause some distortion, and may totally prevent compression from happening. Compression is often accused of dulling drawemr sound being processed, and a little explanation is needed to understand exactly why that is. The Peak limiter has no bypass control, but turning the Level control fully clockwise will prevent any unwanted limiter action.

Avoid running at very high output levels as this reduces the available amount of signal headroom and could lead to distortion in extreme cases. This item may be a floor model or store return that has been used. Sets the rate at which the system gain returns to normal after the input signal level has fallen below the threshold. Typical examples include adding extra brightness to steel-strung acoustic guitars or electromechanical pianos, but the applications are limitless and may be extended to drawmre all manner of synthesised and sampled sounds, percussion and vocals.

Very generally, the ‘hard’ ratio setting provides the most positive means of controlling gain and is invariably the preferred choice if the compressor is to be used creatively. For your own safety it is important that you use this cable. Everything is in good working shape when it is shipped to you. The standard method is to insert some boost of the obtrusive frequencies so the compressor side chain ‘sees’ more of these frequencies and applies more compression than would be normally applied.

In the ‘Soft’ mode, the onset of compression is progressive over a nominal range of 10dB, while in ‘Hard’ mode, gain reduction is applied as soon as the threshold is reached. In general, when ‘Soft’ is selected, a higher compression ratio may be used without compromising the sound quality. vrawmer

See all condition definitions – opens in a new window or tab A variable Enhance control can be used to ‘dynamically’ boost any high frequency energy lost during the full band compression process and has sufficient range to add additional ‘Spectral Energy’ to the programme material for creative processing.

Both the input and output XLRs may be used either balanced or unbalanced, the wiring convention being: See terms – opens in a new window or tab. Mouse over to Zoom – Click to enlarge. Seller information clairusedgear Replace with a correctly rated fuse for the selected operation voltage. By adding, say, a 10dB boost centered at 7kHz, the sibilant sounds fed to the side-chain will be emphasised and, as a consequence, greater gain reduction will be implemented whenever any sibilance occurs.

What happens is that bass sounds, which contain most of the energy in a typical piece of music, cause the compressor to operate, and so any quieter, high frequency sounds occurring at the same time as the bass sound will also be turned down in level.

Once the compressor has been set up normally, the Enhance control setting may be increased as desired. Alternatively, it may be deliberately driven into limiting to produce creative effects. This control sets an absolute limit that the output signal may not exceed.

Avoid mounting the unit directly above power amplifiers or power supplies that radiate significant amounts of heat and always connect the mains earth to the unit. Conversely, by selecting a compression ratio of 1: Contact the seller – opens in a new window or tab and request a shipping method to your location. Effects created by lengthening the attack time are more pronounced when the DL is set for ‘Hard’ compression. The most common use of this connection is to patch in some equalisation for ‘frequency sensitive’ compression, normally called de-essing.

When selected, Auto disables the Attack and Release controls and continually optimises the attack and release times to suit the dynamics of the material being processed. This is useful if an external processor, such as an equaliser, has been connected via the rear panel insert socket.

Alternatively, set the Peak limiter Level to the desired value and then adjust the compressor Gain control to ensure minimum limiter activity. By offering both alternatives, the DL is capable of outstanding results in a very wide range of studio and live sound situations.

If the output signal is so high as to cause the limiter to operate for more than 20mS, the system gain is automatically reduced to bring the signal back within range. The ratio setting depends on how firmly the signal dynamics need controlling; as a rule, higher xl251 provide a higher degree of control but also tend to be more audible in operation dl521 high levels of gain reduction are required, especially when the ‘Hard’ setting is selected.
