DRAWMER / DL441

This 4-channel compressor features four of DRAWMER's innovative auto-compressors. The automatically controlled attack and release times ensure simple and precise operation.

Features
- 4-channel design with stereo linking for channels 1-2 and channels 3-4
- Knee compression has a soft/hard switch button, allowing ratio control in both modes
- Attack and release times are auto-set
- Peak limiter setting possible (0dB to +16dB) using the same zero response time/zero overshoot circuit as the DL241
- Gain reduction (8-dot LED) on all channels, and an LED bar graph (5-dot LED) displaying the output level
- Output level adjustable from -20 to +20dB
- Direct bypass between input and output jacks allows signal to pass even when the power is off
- Input/output level switch (+4dB/-10dB) on the rear panel, and XLR input and output jacks are used

Functions
Compressor:
The compressor section can be switched between HARD and SOFT knee compression. In SOFT mode, the ratio gradually increases over a 10dB input level range until it reaches the ratio set on the front panel, resulting in a more natural-sounding compression sound. This is particularly useful in many broadcast applications. HARD knee compression can also be used as a creative effect, particularly when processing drum and guitar sounds, or to give rock vocals a ""compressed"" sound.

Auto Attack & Release:
By generating a response that constantly follows the signal's dynamics, the DL441 eliminates the need for manual adjustments. This allows the DL441 to maintain crisp transients without introducing excessive peaks. A smooth, lively recovery from compression minimizes side effects such as ""pumping"" and ""breathing."" This feature is particularly useful when the program being processed does not have predictable, consistent dynamics, such as a complete mix, vocals, or ""slap-and-pull"" bass guitar.

Peak Level Limiter:
The ""Zero Response Time,"" ""Zero Overshoot"" circuitry provides absolute limiting of the output signal's peak level, adjustable from 0dB to +16dB above system level. The ""Zero Response Time"" transparent limiter means the DL441 provides complete overload protection from even the fastest and shortest signals, making the unit ideal for protecting speaker systems in sound reinforcement applications. This sophisticated circuitry also prevents undesirable distortion when used for digital mastering.

Metering:
A comprehensive bar graph display shows gain reduction, input and output signal levels at a glance. When the channel is in bypass mode, the output bar graph displays the input signal level. Additional LEDs indicate the status of hard/soft compression, bypass, peak limiting, link, and power-on functions.
