New for 2007 the improved Emitter Exclusive models

New: Gold plated pcb board with transparent solder mask
New Option: Bypass Input and 2 balanced XLR Inputs
Connection of 2 or more Emitter fo Mono-and bridged operation

Since spring 2007 the pcb board of the ASR Emitter are gold plated with transparent solder mask.

This is the optimal combination with the teflon isolated massive silver wire used throughout for
all signals from input to output. From the long time stable and durable surface with very low contact resistance the sound of the new version of the Emitter has got an even wider, more open soundstage, a smoother sound figure together with an improved precision and more impact in Bass.

Through the transparent soldering mask the attractive nearly symmetrically designed board is clearly visible. Also the pcb boards in the power supplies had been improved and are now also gold plated.

New Options: a second XLR input is available for EM II and a bypass input which bypasses the volume control- to use the Emitter together with a preamp as a main amplifier and for home cinema.

The optional Digital control can be used to connect and control 2 or more Emitters.

This can be used for several advantages: for home cinema with 2-3 or more Emitters, for using two stereo Emitters as mono amplifiers for each channel for Bi-Amping, for active operation by using one channel for high and one channel for low frequencies, an bridged mono amplifiers with about 4x Output capacity -- the Emitter II can deliver in this mode about 2000 Watts into 4 Ohms.


ASR Basis Exclusive


	In the Cutting Edge by Harry Pearson: "The ASR phono stage is the best unit I've experienced in all my ventures into cartridge land..." "This new version of the phono stage has all the muscle you'd ever want, dynamic "jump" that will make you jump, as well as top-octave response that... just keeps on going." "The ASR is a product and at the head of its class... This is more like the real thing than we've been able to achieve yet from an analog setup."

	The ASR Basis Exclusive is our most complex Phono preamplifier and is in series equipped with the expensive MIL chip AD 843 SQ. The external power unit is based on the Battery-power unit for the ASR emitter with 400.000 uF additional filtering. In the housing of the ASR basis a buffer with a further 700.000 uF is installed. Price: $5950.


ASR Mini Basis



ASR Emitter 1


	The new ASR Mini-Basis Phono-Preamplifier is built in a case made from high-quality, lightly transparent acrylic glass like all ASR amplifiers. The inscription is engraved and coloured by hand. The Mini-Basis is adjustable in the input impedance (22, 100, 47.000 ohms) and in the gain (+10dB, +16dB, +30dB, +35dB, +40dB)to use it with all usual MM (Moving Magnet) and MC (Moving Coil) pickups. Price: $990.

		The ASR Emitter I amplifier is the entry model, offering all the qualities of the ASR Emitter- family. Separate power supply are keeping electromagnetic fields and vibrations away from the control unit. The power supply unit is equipped with two large and powerful PM (Philbert-Mantelschnitt) transformers with a smaller PM transformer for Standby operation, .The two power transformers are switched ON softly with 5 high power relays in the energy saving mode. If required, they can be switched via a current limiter into normal operation mode. Price: $12,950. Click on picture for more info


ASR Emitter 1 Exclusive


	The Emitter I Exclusive offers the consistent and further development of the Emitter I. All latest improvements of the Emitter I are integrated into the Exclusive version Price: $15,500. Click on picture for more info


ASR Emitter 2


		The sovereign entrance into the class of our large integrated amplifiers. The ASR Emitter II amplifier was developed in order to drive the most pretentious loudspeakers with ease of power. A basic requirement for this unit is an over dimensioned current supply: For each channel, one separate power unit with two large, heavy and powerful PM (Philbert-Mantelschnitt) transformers with energy saving circuit. In total, 3 transformers generate eight different voltages. Every voltage is rectified individually and pre- buffered. These voltages are used to supply separately the input amplifier, driver and output stages, as well as the control circuit. The ASR Emitter II is connected to the power supply units with 2 double shielded cable, each 2 meters long. The 30 contacts of the plug-in connector are designed individually for 16 ampere. The input sockets are made out of gilded massive brass. The insulator consists of high-quality Teflon. Massive silver wire Teflon coated is used for the music conductors. The 100 Amp speaker terminals with big lever grips allow up to three loudspeaker cables with cable spade connectors for Bi- or Tri-wiring. 4 mm plugs can be connected firmly and secure. To avoid any possibilities of short circuits, the pole terminals are fully -isolated and mounted with 50 mm distance. A wear-resistant step switch adjusts the volume precisely with 32 relays. A micro-controller supervises the correct function of all parts of the amplifier and protects against any possible malfunctions for the Emitter and the loudspeakers. The LED- display has a size of 35 mm and can be easily seen. It keeps you informed what is in process in the Emitter. Depending on the setting, the display switches off after 10 seconds. Under the double-sided main board with special thick copper- tin layers, there are 60 mm2 mass rails, at which the two boards are mounted for the buffering electrolytic capacitors. Inside the Emitter II there are 20 powerful MOS- FET- transistors each with 150 watt, high-grade ceramic input circuits, fast foil capacitors and electrolytic capacitors with a total of 562.000 uF. Price: $22,000.

	The ASR Emitter II Exclusive version: The ASR Emitter II Exclusive amplifier sets another milestone in the consistent further development of the Emitter II. All possible improvements of the Emitter II are integrated into this version. The sound picture is very fast and dynamic, and the audio solution is increased. Furthermore, the sound is quiescent and even more relaxing, smooth and homogeneous. Through its extremely high speed, the Emitter II Exclusive reproduces authentically the three dimensions of good recordings into the listening room. The sound is faultless to such a degree that the audible location of the loudspeakers at the listening position is nearly impossible. The two Exclusive power supply units achieve an essential part of these tonal improvements. The well-constructed units are equipped with increased powerful transformers with improved magnetic core material, 56 ultra-fast rectifier diodes and 166.000 uF electrolytic capacitors. In the Exclusive power unit 8 different voltages are generated. They are used to supply the input amplifier, driver and output stage, as well as the control circuit separately. A special ferrite shielded power cable, 3x 2,5 qmm with a definite filter characteristic avoids the influence of high frequency power supply distortions and improves dynamics. The Emitter II Exclusive is equipped with a military high grade driving chip, faster foil capacitors and electrolytic capacitors with a total of 862.000 uF. Price: $24,900


ASR AKKU

For a perfect sound and musical picture, an amplifier has to be supplied with a very clean and stable supply voltage to the input stage. This is of the up-most importance. You have the option to supply the input stage of the Emitter with a perfect voltage, achieved with a separate accumulator power unit.

A separate unit is supplied with the Emitter and is connected with a separate cable to the control unit. The accumulator power unit consists of 6 accumulators, each 6 Volt/12 Ah, plus an additional buffering capacity of 400.000 uF. An automatic charging circuit is incorporated.
When the Emitter is switched OFF, the accumulators are charged with a low current supply.
Price: $2,900.
