Hiato Integrated Amplifier

With 300 watts per channel the Hiato integrated stereo amplifier is a serious piece of equipment capable of driving big, difficult to drive speakers. It masters complex musical pieces that many dedicated power amps struggle with to give you spine tingling detail in the treble and control over the bass and mid range that is a pure delight.

If you are looking for an integrated amplifier solution in your music system but you don't want to sacrifice the benefits that true, well controlled power can bring then this amplifier is for you.

The rear panel layout includes four line level inputs and a user adjustable phono input. High quality WBT RCA connectors are used on all line level and phono inputs with additional balanced XLR inputs for CD and Line 1. It has RCA and XLR HT bypass input, remote IR input and 12V input/output triggers. There are four pairs of output connectors allowing bi-wired speaker applications, line level output for archiving and pre-out for bi-amping. The phono stage is optional.

On the front panel a small, unobtrusive 3.5mm jack allows a casual user to connect portable media, and the Hiato's full function remote control also operates the Plinius CD players.

Optional Phono Stage
The preamplifier can be fitted with an optional phono stage based on a scaled version of the Koru design. The Phono has four gain settings and five loading settings to allow for suitable cartridge matching.

Line Out
The Line out provides a line level output, carrying the selected source signal. The Line Out allows for the signal to go on to recording equipment, headphone amplifiers or sub-woofer speakers.

Remote Trigger Input and Output
Terminals for remote trigger connection allow a processor signal to bypass the preamplifier stage or instigate the power amp to come out of standby.

RC5 input
The RC5 input allows for connection to wired remote interfaces so it can be used as part of an automated system.

Ground Lift Switch
This allows for the signal ground to be isolated from the main chassis earth. This can assist in resolving unwanted ground loops or hum due to duplicate ground paths in some systems.

WBT and Neutrik Connectors
High quality WBT RCA and Neutrik XLR input connectors are fitted along with WBT output speaker terminals to ensure low distortion interface between your cables and the amplifier.

Auricap capacitors
Audience AV supply the Auricap XO capacitors used in key areas of the circuit. The Auricap was chosen for its superior clarity and dynamic ability.

Siltech Wiring
Siltech premium 'G7' silver/gold wire provides a perfect connection between components to give clear, fast and detailed presentation of the music signal.

Auric Wiring
Audience AV supply the Auric OFC wire used in the input stage of the amplifier. The Auric was chosen for its high workability and natural sound.

Aluminium Construction.
The aluminium lid and panels provide a non-magnetic cover to reduce unwanted magnetic fields that can interfere with the sensitive audio signals.
