Drawmer DL251

The DL251 'Spectral Compressor', incorporates a variable 'Dynamic Spectral Enhancement' (D.S.E.) section which eliminates the problems associated with full band compressors by restoring the high frequency energy lost during the full band compression process. This enhancement circuitry is extremely effective where compression and limiting are employed for broadcast transmission, or across complete mixes in a stereo mixdown situation. 'Dynamic Spectral Enhancement' has many creative applications when recording individual components at the multi-track stage, particularly on such programme as acoustic guitar, piano, brass and vocals.


Compressor. The compressor section can be switched to provide either HARD or SOFT knee compression In both the HARD and SOFT modes a Ratio control is available In the SOFT mode the ratio increases gradually over a 10dB input level range until it reaches the ratio set on the front panel control, thus achieving a more natural sounding compression.
Selectable manual or automatic Attack and Release times dramatically extend the application range and user scope of the DL251.
Selecting the 'Auto' mode removes the need for manual adjustment and is particularly valuable when the programme being treated does not have predictable or consistent dynamics, such as on complete mixes, vocals or 'slapped and pulled' bass guitar. Under manual control the wide range of adjustment available gives the user the ability to create dynamic effects as well as normal compression.

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. When no compression is taking place, the 'Dynamic Spectral Enhancement' circuitry is inoperative and so no change is made to the signal. However, as the signal level rises to the point where gain reduction is taking place, the Enhancement system 'kicks in' applying dynamic boost which is directly related to the amount of gain reduction taking place. A front panel switch offers an instant A/B comparison of this feature and a green LED indicates the amount of enhancement taking place.
Metering. Comprehensive bar graph displays give 'at a glance' indications of gain reduction, and input/output signal level Gain reduction from 1 dB to -30dB is shown simultaneously with signal level from 20dB to + 15dB Other single LEDs indicate function status of Hard/ Soft compression, Auto Attack/ Release, Side chain monitoring, Bypass, Enhancement, Peak Limiting, Stereo Linking and Power on.
Side Chain Listen. A front panel push button with LED status enables the monitoring of any external processing applied to the side chain access connections on the rear panel.


The DL251 is provided with balanced inputs and outputs on XLR connections.
Short Description It is well known that compression, in its basic form, tends to remove high frequencies from any material with a wide bandwidth.
