Hand-crafted in Berlin, Germany, the TSM combines 32 DB25 inputs and 8 TRS inputs with active NOS tube circuitry and custom output transformers, bridging digital accuracy and vintage analogue warmth.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"1581\" height=\"728\" src=\"https:\/\/www.youtube.com\/embed\/ayo_j-kN8jo\" title=\"Tegeler: 40 Channel Summing Mixer | Full Demo and Review\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eActive Tube and Transformer Output Architecture\u003c\/strong\u003e\u003cbr\u003eAt the core of the TSM is an active output stage built around high-grade NOS 12AU7\/ECC82 valves and custom-matched audio transformers. Unlike passive summing boxes that require external preamps to recover lost signal levels, the TSM delivers full line-level output independently. The internal mix bus provides up to +22 dBu of headroom, introducing natural harmonic saturation and gentle transient smoothing while keeping frequencies open, sweet, and three-dimensional.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStepped Output Attenuation for Total Recall\u003c\/strong\u003e\u003cbr\u003eTraditional analogue consoles often introduce level drift and recall inconsistency due to variable potentiometers. The TSM solves this workflow barrier by utilising a precision 6-stage stepped rotary output switch operating in -3 dB increments (down to -15 dB). This allows engineers to drive stems hard into the tube stage to capture rich harmonic saturation, then attenuate output levels in exact decibel steps for clean A\/D converter headroom and 100% accurate session recall.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Density 40-Channel Architecture with Flexible Routing\u003c\/strong\u003e\u003cbr\u003eAccommodating large multitrack sessions, the TSM features 40 balanced line inputs split between four 8-channel DB25 connectors (Tascam layout) and eight Neutrik TRS jack inputs. For simplified mono tracking, plugging a mono source into the lower TRS jack of a channel pair automatically routes the signal to both left and right buses, placing it dead-centre in the phantom stereo field. Multiple TSM units can also be cascaded for expanded channel counts or surround setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e40 balanced line inputs comprising 32 DB25 channels in Tascam layout and 8 Neutrik TRS channels\u003c\/li\u003e\n\u003cli\u003eActive tube and transformer output stage powered by dual NOS 12AU7 \/ ECC82 valves\u003c\/li\u003e\n\u003cli\u003ePrecision stepped output rotary switch with -3 dB attenuator increments for 100% mix recall\u003c\/li\u003e\n\u003cli\u003eInternal mix bus design providing up to +22 dBu of analogue headroom\u003c\/li\u003e\n\u003cli\u003eDual illuminated analogue VU meters for precise master output monitoring\u003c\/li\u003e\n\u003cli\u003eAutomatic phantom-centre signal distribution for mono sources on lower TRS inputs\u003c\/li\u003e\n\u003cli\u003eStereo XLR balanced output connections for seamless converter and mix bus integration\u003c\/li\u003e\n\u003cli\u003eUnit cascading support for expanded track counts and surround sound configurations\u003c\/li\u003e\n\u003cli\u003eHand-built construction in Berlin, Germany with internal linear toroidal power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTech Specs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoduct type:\u003c\/strong\u003e Analogue Tube Summing Mixer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Count:\u003c\/strong\u003e 40 Channels (32 DB25, 8 TRS Jack)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Connectors:\u003c\/strong\u003e 4 × DB25 (Sub-D, Tascam layout), 8 × 6.35 mm TRS Jack (Neutrik)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Connectors:\u003c\/strong\u003e 2 × XLR Balanced (Left \/ Right Stereo Output)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive Circuitry:\u003c\/strong\u003e Dual NOS 12AU7 \/ ECC82 Tubes \u0026amp; Custom Output Transformers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMix Bus Headroom:\u003c\/strong\u003e Up to +22 dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Input Level:\u003c\/strong\u003e +22 dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Output Level:\u003c\/strong\u003e +24 dBu\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e ≥ 10 kΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e \u0026lt; 600 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20 Hz – 40 kHz (±1.5 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic Range:\u003c\/strong\u003e ≥ 110 dB (Unweighted)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel Crosstalk:\u003c\/strong\u003e \u0026gt; 90 dB @ 1 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Level Control:\u003c\/strong\u003e Stepped attenuator (-3 dB increments down to -15 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetering:\u003c\/strong\u003e 2 × Backlit Analogue VU Meters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e Internal linear PSU with toroidal transformer (230 V \/ 115 V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e \u0026lt; 25 W (500 mA slow-blow fuse)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack Dimensions:\u003c\/strong\u003e 2U Rackmount (88.1 mm H × 483 mm W × 250 mm D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 7.5 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e Germany (Berlin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiscover Tegeler Audio Premium Solutions:\u003c\/strong\u003e \u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003ca rel=\"noopener\" style=\"color: rgb(43, 0, 255);\" title=\"Discover Tegeler Audio Premium Solutions\" href=\"https:\/\/www.tegeler.com\/en-US\/TubeSummingMixer\" target=\"_blank\"\u003ehttps:\/\/www.tegeler.com\/en-US\/TubeSummingMixer\u003c\/a\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003e\u003ciframe width=\"1581\" height=\"728\" src=\"https:\/\/www.youtube.com\/embed\/6FvliSCKrDA\" title=\"Tube Summing Mixer Hip Hop (no talking)\"\u003e\u003c\/iframe\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Tegeler Audio","offers":[{"title":"Default Title","offer_id":67969802829860,"sku":"TEG_TSM","price":32885.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/8294\/files\/ADSRS_TEG_TSMimg01.png?v=1793557135","url":"https:\/\/www.audiosaurus.co.za\/products\/tegeler-audio-tube-summing-mixer","provider":"Audiosaurus ","version":"1.0","type":"link"}
