ASR Emitter I und Emitter I Exclusive model 2016

Transcription

1 ASR Audio Systeme Friedrich Schaefer Hohe Straße 700 / 5A D Herborn Telefon Telefax Internet ASR Emitter I und Emitter I Exclusive model 2016 The new Emitter models have a new even more symmetrical designed PCB Board. With nearly all parts and led placed that the left is nearly the mirror of the right channel. asr@asraudio.de The boards are more stable from 2,4 mm FR4 material, with 110u Copper (1,4 mm with 70u before). The output transistors are equipped in the new version with 1 mm High grade Ceramic Isolators for a much better electrical and acoustical isolation. That is a large much improvement compared to the thin Kapton isolation washers used before. High grade pure copper audio resistors in signal path for smoother reproduction. High Voltage Elkos in Main unit and Battery PSU included in Exclusive version, Optional for Basic versions. Also new HV Elkos are used for input and output stage on the main board. Emitter I Exclusive with Brass block on the input circuit as at Emitter II Exclusive. Decoupled voltage supplies at all 6 voltages for both channel at Emitter I Exclusive. Decoupled supplies fur input stages and offset correction and buffer stage. The relays for switching between battery and line operation of the input stage are now separate for both channels and voltages. This means lower losses and improves the dynamic in both modes. Energy modes is shown at the main board with a yellow Led, Full power with a blue Led. Volume control with additionally relay to damp the signal down in Off Mode. Improved safety circuit with improved detection from offset and Overload faults. Modified switch OFF delay in case of overheat, to first to energy mode to allow the unit cool down. More adjustment possibilities : Adjustable Sub or Pre-out with 6 and 12 DB adjustment for Subwoofer and pre out for slave amps. Additionally precision trimmer for precise adjustment of the output voltage allows the connection to subwoofer or separate second main amplifiers without volume control. Compensation switch with 4x Dip switch per channel for smoother adjustment at Emitter I. That allows more delicate adjustment of the sound figure with slower or faster rise time. Input resistance adjustable between 22 k and 1 K with 4 Dip switches. That allows also a fine trimming of the resistance to get a better match with cables and sources. Also allows the fine tuning of the sound figure and lower losses in longer cables.

4 New design : Both Emitter I models get a new faceplate with a more elegant engraving, The left knob with the modes have shorter names with O, S, 1, 2 (optional with O, S, 1, 2 3, 4, 5, 6, for versions with headphone or second output) the right knob for the inputs is named from 1 to 5 ad D for Direct (6, 7 with optional more inputs Back plate with separate placed inputs and outputs and new round XLR Connector from switchcraft Blue display comes now without separate engraving.

5 Inputs : The balanced converter is now integrated in the main board, and is also available with 2 balanced inputs for Emitter I. New input selector with 2x On signal-relays that switch signal and signal ground together. To get an improved sound figure with multiple signal sources from avoiding ground loops. The Emitter now operates also with several sources connected as there is only one. Basic version : 5 unbalanced RCA inputs marked with 1-5, 1, direct input, 1 Output, Option : Balanced input instead of 1 RCA, 6 or 7 input, Sub out adjustable. Exclusive : 3 unbalanced ( marked 1-3 ) 1 WBT CU ( marked 4 ) and 1 balanced input (5), 1 direct input, 1 output, Pre and Sub output, adjustable with 2x Dip switches for Subwoofer and external main amplifiers Optional for both models : maximal in total 7 inputs with between 5 to 7 unbalanced inputs And 1 or 2 balanced inputs, Tape monitor or equalizer loop More before optional equipment comes as Standard : Emitter I Basic now comes in series with built in active Power parts for Trafo PSU and Elma switches with Copal optical rotary encoder from. Emitter I Exclusive with new HV ICS, HV Elkos for input and output stage, Brass Block for ICs and 80 V HV Elkos in series, 8 qmm silver ground cable. splitted Supply to the both channels for all 6 voltages Battery PSU comes with HV Elkos as standard equipment, The Battery PSU with the before optional HV Elkos as standard is now less expensive than before.

6 The technique of the ASR Emitter I : two channel amplifier in the acrylic casing with input selector and volume control. Class A/B technology with 12 Toshiba special Audio-MOSFETS with high impulse capacity. Mounting bars of the output Transistors made from massive brass for low resonance. 1 mm High grade Ceramic Isolators for a much better electrical and acoustical isolation. Circuit board 2,4 mm, double sided with especially strong, 2x 110u copper. Most parts of the two channels in mirror-symmetrical order. Compensation switch with 4x Dip switch per channel for smoother adjustment at Emitter I Input resistance adjustable between 22 k and 1 K with 4 Dip switches. Volume control with relay attenuator in 1dB-Steps with balance and input level adjustment. 25 mm LED-Display available in yellow or blue as operational indicator, adjustable in many ways 5 high-level-inputs switched with relay, plus 1 direct input, 1 non regulatet output. Gold plated massive brass RCA-sockets with Teflon isolation. Massive silver-wires for all signals. large 60 amperes binding post for cable-shoes and 4 mm banana-plugs, WBT Nextgen as Option Protection-circuits against overload, Clipping, Short-circuit, Overheating and DC Offset. External power supply with 3 transformers ( Philbert at Exclusive ) energy-management, separate rectification for each of the 8 voltages or 32 Schottky rectifiers. Especially stable power supply casing of high-quality, very stable steel sheet metal. Low loss Neozed high load fuse built in the power supply unit. stable industrial power connector from Harting for the connection to the amplifier-part. Double shielded connection cable to the amplifier-part 2,5m long, on wish other lengths. Power cable ASR Magic cord 1,5 m with low loss 21A power connector at the power supply. high-quality ASR design remote control made from Corian for all functions. Additionally equipment of the ASR Emitter I Exclusive Buffering capacitors with total uf. Balanced input for CD with switchable input impedance( optional 2 inputs ) Adjustable Sub or Pre-out for Subwoofer and pre out for slave amps. feets made from of massive brass for the amplifier unit available in chrome or gold.
