In normal use, the release time should be set short enough so that the system gain has returned to normal before the next peak occurs and, in general, it should be set as short as possible before audible gain ‘pumping’ occurs.

This switch configures the channels for processing stereo programme material where the left hand channel’s controls act as master for both audio rdawmer. This item will be shipped through the Global Shipping Program and includes international tracking.

However, the DL’s Dynamic Spectral Enhancement feature is designed to prevent the above side-effect by applying dynamic boost to a selective part of the audio vl251 during the period drawmwr compression.

This item may be a floor model or store return that has been used. That’s why the cymbals and hi-hats in a heavily compressed drum track seem to dip in level whenever a loud bass drum or snare drum beat occurs.

In general, this setting will produce the least obtrusive level control on signals with widely varying dynamics such as complete mixes. By offering both alternatives, the DL is capable of outstanding results in a very wide range of studio and live sound situations. Sets the compression ratio in the range 1: Because the Dynamic Spectral Enhancement system is dynamically related to the amount of gain reduction taking place, it is necessary to set up the drawmre accordingly.


Compression is often accused of dulling the sound being processed, and a little explanation is needed to understand exactly why that is. If the dl2511 panel Link button drqwmer set to Peak, then the gain reduction is controlled by the peak level of whichever channel is loudest at any time. A partial solution is drawjer to use less compression or increase the attack time to allow the leading edge of the brighter sounds to pass through the compressor before the gain reduction occurs. Offered for sale is one 1: In the ‘Soft’ mode, the onset of compression is progressive over a nominal drawmeer of 10dB, while in ‘Hard’ mode, gain reduction is applied as soon as the threshold is reached.

A typical example is a hi-hat sound occurring at the same time as a bass drum beat; as the compressor pulls down the gain in response to the bass drum level, the hi-hat will be reduced in level by a corresponding amount. A variable Enhance control can crawmer 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.

Drawmer DL251 Stereo Spectral Audio Compressor Limiter Enhancer

Lititz, Pennsylvania, United States. The DL contains advanced circuitry which dynamically controls the phase and spectral content of the programme material to lift transient detail during times when compression is applied, and the degree of processing is related to the amount of gain reduction taking place. The choice of Peak or Average linking is down to user preference and must be selected via the rear-panel switch.

In Peak mode, the gain control of both channels is derived from the peak level of whichever channel is currently loudest, while in Average mode, the control signal is derived from the average of the two channel levels.

This enhancement circuitry is extremely effective where compression and limiting are employed for broadcast transmission, or across complete mixes in a stereo mixdown situation. Image not available Photos not available for this variation. Selectable manual or automatic Attack and Release times dramatically extend the application range and user scope of the DL You are covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing.


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. Back to home page Return to top. Mouse over to Zoom – Click to enlarge.

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. Selecting a long decay time will help maintain a high average level of gain reduction while not interfering with the short-term dynamic detail of the signal.

This control sets an absolute limit that the output signal may not exceed. The DL also includes the newly developed Dynamic Spectral Enhancement system which is designed to compensate for the loss of transient detail that tends to occur during periods of heavy compression.

This limiter is very fast dl2251 enabling it to control any peaks without audible distortion. Learn More – opens in a new window or tab Any international shipping and import charges are paid in part to Pitney Bowes Inc. Learn More – opens in a new window or tab.

There are drawker items available. It is well known that compression, in its basic form, tends to remove high frequencies from any material with a wide bandwidth. Conversely, by selecting a compression ratio of 1: For use with unbalanced systems, the Cold pin 3 must be grounded at both darwmer and output XLRs. Both the input and output XLRs may be used either balanced or unbalanced, the wiring convention being: People who viewed this item also viewed.

Effects created by lengthening the attack time are more pronounced when the DL is set for ‘Hard’ compression. In this configuration Peak type Linking should deal with the programme correctly, without any stereo sound shifting.
