Up for sale is a world-class SPL Transient Designer Model 9842 4-channel dynamic processor in excellent condition. Purchased brand new and recently decommissioned from active service in a pro studio, this legendary 1U rack unit gives you four independent channels of SPL's revolutionary Differential Envelope Technology. It is the definitive analog tool for shaping the attack and sustain of acoustic drums, percussion, and full mix elements completely independent of signal level. Condition & Details

• Studio History: Meticulously cared for and housed in a clean, smoke-free, climate-controlled professional control room environment. 
• 4-Channel Capability: The Model 9842 configuration is highly coveted for tracking and mixing, allowing you to process a full drum shell kit (Kick, Snare, Rack Tom, Floor Tom) or multiple stereo stems simultaneously. 
• Cosmetic Condition: Excellent overall aesthetic shape. The classic silver and blue front panel, control knobs, and active LED indicators are clean, crisp, and fully intact with only minimal, negligible signs of standard rack mounting. 
• Functional State: 100% operational across all 4 channels. All Attack and Sustain rotary potentiometers, individual channel bypass switches, and stereo link toggles engage and sweep flawlessly without any noise or static.
