Updated! Reality TSM120-271

Reality is summing mixer with passive summing network and powerful tube all balanced amplifier with high headroom/overloading capacity, wide dynamical range and low noise floor. This is new incaration of the device.

Audio Review

The signal path is pure tube.  So, after years and many positive reports, this version got  improved new, more powerful gainup amplifier with big octal tubes, what positively affected the bass articulation and transients dynamics.

The device ouput is outfitted with specially designed, powerful (10WA) custom wound transformers (with a Hi-Mu core made of rare material), and which can be subjected to any active load with no harm to the sound or matching with other devices.

To eliminate ground loop hum the gainup amplifier  assembly is completed with consideration for the topology of the given circuits.

The entire signal path is executed as point-to-point design between tube pins and solder lugs. There are no electrolytic capacitors - only high-ouality film capacitors. Electrolytic capacitors are only used in the power chains. The high quality passive components are used throughout.

All audio chains are built with high-quality wire.

Passive summing  network.

As Input Gain attenuators  is used high reliable ceramic stepped switces with dual knife contacts covered by thick silver layer, with 11 patterns, in turn, Output Level stepped controls boasts for 24.

The rear panel houses balanced inputs with 25 pin D-sub connectors, main and extra XLR outputs, transformer balanced,  also direct balanced XLR inputs to mixer amplifier, military grade DC connector for connection with outboard PSU.

In order to minimize power net noise and hum the device  power circuit performed as outboard 2U unit, and uses a stabilized DC voltage for plate and filament.

In turn, PSU rear panel houses standard IEC mains connector with fuse, and DC output to feed the device. Dedicated DC cable (~1.5m lenght) is part of rig, of course.
