Atoll PH100 Phono-Stage MM/MC

The Phono-Preamp PH100 ​​fulfills all the wishes of a real vinyl enthusiast.

In its robust steel housing with a 4mm aluminum front, the sensitive amplifier electronics are protected from interference and interference fields.

The power supply is separate for each channel with transformers from the Atoll top range. 4 voltage stabilizers filter all unwanted interference.

The preamplifier electronics is completely made up of discrete components (no OpAmps!) And does not require sound-reducing coupling capacitors.

MM and MC low- or high-level pickups can be connected - an adjustment of the input impedance and input capacitance is possible.

The PH100 ​​can be used with any device that has a free RCA input.

Peculiarities:

• Dual mono design
• Discrete element base
• Flexible parameter setting

Apogee Duet FireWire 24-bit / 96 khz Audio Interface (Mac OS Big Sur 11.5.4), 2007, made in USA

  

Link: apogeedigital | [Owner's Manual, PDF]

Work in Mac OS Big Sur 11.5.2-11.5.4

Key Features

• 2 Channel Input
• 2 Channel Output
• 24-Bit/96kHz
• Mic Inputs with 48V Phantom Power
• Bus Powered
• Mac OS X

Duet from Apogee is a FireWire interface for Mac OS X and features two microphone inputs, each with phantom power and up to 75dB of gain. This allows the user to record a vocal track while playing guitar or keyboard, record an acoustic track in stereo, or even capture a live concert. Duet also features dual, 1/4" high impedance inputs that are ideal for any combination of two instrumentalists - guitar and bass, bass and keyboard, guitar and guitar, etc.

Although somewhat limited in I/O, the main strength of the unit is the prized Apogee conversion. And its multi-function controller knob, combined with the included Maestro Control software is capable of performing a broad range of functions - from assigning the operating levels of the inputs, to controlling the levels of the inputs and outputs, selecting sample rates, and defining the four virtual MIDI controllers.

Duet's studio reference-quality sound combined with simple and powerful control features make it an ideal choice for creating music, creating podcasts, or simply delivering the ultimate iTunes listening experience. The system works with any Core Audio-compatible application, but provides especially close integration with Apple's OS X, GarageBand, Logic and Soundtrack Pro.
