Prisma
The all-new TIDAL Prisma. Transparency and invisibility at a new level. The Prisma’s fundamental design principle was that it had to handle only two tasks: selecting the source and adjusting the volume. It does both with absolute ease and has to be experienced first hand to understand the game-changing way the Prisma takes itself acoustically, completely out of the way from the source and the power amplifier.
A unique concept, the TIDAL preamplifier topology itself and the execution of the complex multilayer PCB boards are the inner heart of the Prisma. On top of all that, the Prisma comes with TIDAL’s legendary fully balanced MC phono input. A line stage like no other and as always embedded into the timeless and iconic TIDAL chassis which is then hand finished to perfection.

SPECIFICATION
Pre amplifier section
- The whole preamp section is built from single parts selected and balanced by hand (discrete match up)
- Symmetrical amplifier design with only two solid state stages in the signal way
- Low distortion and almost complete absence of a signature sound because of a complementary circuit topology, following the concept of the ideal for the shortest signal way, true balanced design in mirror-symmetrical layout onto a 4-layer PCB board
Volume control
- 32 steps volume attenuator with noble-gas filled mini reed relays and super short signal ways fully balanced, this means audio-plus and audio-minus have their own level adjuster, no cascade compromises. No open contacts (to prevent corrosion/dust etc.), and only 1 metal-film resistor in the signal way in the best (and direct) position between signal in and signal out
- Galvanic and optical isolated ADC control from an ALPS motor driven potentiometer to control the relay itself, resolution adapted for each volume level (higher for lower levels, lower for higher levels)
Features
- 3x true balanced inputs and 1 x MC phono input
- When the balanced input is turned off the matching GND connection is in high resistance (100 Ohm) for reducing the ground loop
- 2 x balanced output
- 2 x remote power on/off’s by RJ45 to TIDAL power amplifiers connection
- loop-thru mode free to configure to either input 1,2 or 3 for external AV processor home cinema embedding
Phono stage
- MC phono input, unique two-stage concept between the MC-board and the line-stage itself for the shortest possible signal way from cartridge to the balanced output
- Phono heating for low distortions and perfect temperature of (sound) sensitive parts.
- Fully balanced input impedance to be chosen by the rotary switch at the backside (ELMA precision switcher controlling mini-reed-relay direct in the circuit (from position 1 up to 12): 50, 80, 100, 130, 160, 200, 266, 330, 400, 570, 800, 2000 ohm)
- High-gain/ low-gain selector with a 10dB difference
- Direct soldered connection to the main board using silver air core solid core wires
- Voltage gain: 10 dB (line mode) 20 dB (phono mode)
- Bandwidth: 1Hz – 350 kHz (-3 dB)
- Distortion: < 0.005%
- Noise: 100 dB (0.5 V output voltage)
- Input impedance: 10 kOhms
- Output impedance: < 40 Ohms
- DC-coupled symmetrical MC-Class-A amplifier: voltage gain: 55 dB (at 1 kHz), noise: > 80 dB (0.5 mV input voltage), input impedance: 10 – 1.2 kOhms, output impedance: 150 Ohms
- Dimensions: 17.3″ x 4,7″ x 15,3″ / 44 cm x 13 cm x 39 cm
- Weight: 70 lbs. / 32 Kg incl. packaging
