Parasound Halo Series P 6 Preamplifier with Home Theater Bypass and ESS DAC
Halo is Parasound’s premier line with a reputation for going head-to-head with the most expensive equipment on the market, while costing a fraction of the price. Halo has earned honors and awards that are unmatched. The P 6 is a quantum leap in audiophile preamplifiers.  It’s ultra-high resolution DAC, built-in phono stage and balanced XLR inputs and outputs, are sure to surpass your expectations. It’s the perfect product if you want a great two channel music system that integrates with your existing home theater without sacrificing subwoofer functionality.
High Resolution Digital to Analog Converter
The P 6’s built-in 32 Bit DAC (Digital to Analog Converter) uses a ultra-high resolution 384kHz ESS Sabre32® Reference DAC IC. The asynchronous USB input supports PCM up to 384kHz/32-bit and DSD256.  The 2 optical and 1 coax inputs can decode high resolution PCM audio up to 192kHz/24-bit. The P 6’s DAC is superior to the DACs in most digital source components.  These sources will sound better if you connect one of their digital outputs to the P 6's DAC instead of connecting their analog output jacks. 
Phono Input & Balanced XLR Inputs/Output
The P 6 is equipped with a high-quality phono stage with a three-position load/gain selector switch making it compatible with all cartridge types.  Additional analog connections include balanced XLR inputs and outputs. The P 6 also provides one XLR connector and two RCA jacks for one or more subwoofers.
High & Low Pass Crossovers
An especially useful feature of the P 6 is it’s innovative high and low pass crossover network. This provides analog bass management for easy integration of subwoofers and stereo speakers. With the P 6 crossover network your subwoofer(s) can easily be shared by two channel and multi-channel playback. This works in tandem with the home theater bypass input for a seamless transition whenever you select two channel or multi-channel operation.
Front Panel Volume Display
The volume control features a new, dimmable - display showing the exact volume setting. Other features include: user defined default turn on volume and favorite volume setting. The solid machined aluminum volume control knob, polished on the front and textured around the perimeter, rotates on ball-bearings giving it rock-solid and silky smooth operation.
Analog Volume Control by Burr-Brown
The P 6 uses a Burr-Brown high-performance, electronically-controlled analog volume control IC with high dynamic range. It functions as an analog switched resistor ladder array so analog audio is never converted to digital as with most IC volume controls. Parasound’s engineers bypassed the onboard gain stage and instead used an external, high-performance operational amplifier with a dedicated power supply. This approach achieves the lowest noise and the lowest distortion resulting in superior sound quality.
Subwoofer Level, Tone Controls & Headphone Amp
The subwoofer level control allows fine-tuning from the front panel.  Bass and Treble Control Knobs offer precision adjustment of tonal balance. A front panel and remote control button provide an easy way to completely bypass the tone control settings. The P 6 is equipped with a dedicated high quality current-feedback headphone amplifier based on the top-grade Texas Instruments TPA6120A.
Home Theater Byass Input
The Bypass input jacks are used to incorporate the P 6 into a surround sound system. The Bypass input works by passing the incoming L, R and Sub channels directly through to the L, R and Sub output jacks.  of the P 6 circuits or controls have any effect on the bypassed signals. The P 6 is thus transparent to the Left, Right and Subwoofer(s) outputs from the surround sound processor or receiver and passes them on to the amplifier(s) and Subwoofer(s).
12V Trigger Output & Rear Panel IR Input
If the power amplifier is equipped with a 12 V trigger input you may find it convenient for the P 6 to turn it on and off automatically.  The P 6 is compatible with most popular infrared repeater systems for remote control operation from another room or when the P 6 is installed in a cabinet where its remote handset signals cannot reach its front panel remote control sensor. The IR Control Input connector is a standard 1/8” (3.5mm) mono “mini” jack.
