24-input/32-output Thunderbolt 3 audio interface The Horizon 8P is a 24-in/32-out Thunderbolt 3 audio interface centered around eight Audient console microphone preamps with ORBIT Control variable impedance functionality. Combined with 32-bit conversion featuring a 133dB dynamic range and 0.99ms round-trip latency, the 8P condenses a complete, console-grade recording front-end into a single rack unit. This product is designed for producers and studios that want to capture performance with true analog texture and headroom. *Measured at 192kHz/Buffer Size: 64 samples ◆Main Features 8 Audient console microphone preamplifiers Variable impedance via ORBIT Control 24 inputs / 32 outputs 32-bit/192kHz compatible 133dB dynamic range 0.99ms round-trip latency (192kHz/64sample) Horizon Control software allows you to daisy-chain up to four Horizon series consoles. ◆Reasons for choosing HORIZON 8P The Horizon 8P packs a complete recording front-end setup into a single 1U rack. Inheriting the David Dearden-designed circuitry from the ASP8024-HE console, eight professional Audient console preamps deliver analog character and 75dB of clean, low-noise gain to any sound source. ORBITControl allows you to change the impedance of each preamp in hardware, shaping the tone of ribbon, dynamic, and condenser microphones at the input stage. For mixing, you can directly connect outboard gear to the DB25's eight line inputs. With 32-bit conversion offering a 133dB dynamic range and 0.99ms round-trip latency, you can record and monitor through native plugins without any noticeable delay. Horizon Control provides one-click access to routing, monitoring, and four cue mixes. ◆From a DSP-centric production environment to a more flexible native environment The Horizon 8P achieves a round-trip latency of 0.99ms when set to 192kHz/64 samples. Recording vocals with compression and EQ applied. Playing with a sound processed through a guitar amp simulator. Layering software instruments and live performances with the same sense of timing. Even in these situations, it provides a response that minimizes the performer's awareness of delay. This system allows you to build a recording system centered around your preferred DAW and native plugins, without being tied to a specific DAW and DSP environment. It enables you to create a low-latency recording environment without limiting your production tool choices. ◆Scalable system configuration with up to 4 units The Horizon series allows you to daisy-chain up to four units on a single driver. The entire system supports a maximum of 200x200 I/O. *When using 4 Horizon32 units. From small private studios to production environments with multiple booths, the system can be assembled according to the number of inputs and outputs required. ● Technical specifications • Microphone Preamps: Audient Console Microphone Preamps x 8 Input terminal: Combo jack Input gain: 0-75 dB Phantom power: DC +48 V, 10 mA per channel Pad: -10 dB Variable high-pass filter: 20–250 Hz ORBIT Variable Impedance Control: Low 220 Ω ORBIT Variable Impedance Control: Medium 1,200 Ω ORBIT Variable Impedance Control: High 2,800 Ω Microphone preamplifier maximum input level: +18 dBu Microphone preamplifier THD+N (at 0 dBu): -98 dB / 0.0011% Microphone preamplifier EIN: -129 dB (A-weighted) Microphone preamplifier frequency response: ±0.5 dB, 10 Hz to 80 kHz Microphone preamplifier CMRR: 75 dB or higher Analog performance ADC maximum input level: +24 dBu = 0 dBFS ADC THD+N (at -1 dBFS): -118 dB/0.00012% ADC Dynamic Range: 127 dB (A-weighted) ADC frequency response: ±0.2 dB, 10 Hz to Fs/2 (Nyquist frequency) Maximum line output level: +24 dBu = 0 dBFS Line output THD+N (at -1 dBFS): -122 dB / 0.00008% Line output dynamic range: 132 dB (A-weighted) Digital conversion DAC: 32-bit DAC Dynamic Range: 133 dB Round-trip latency: 0.99 ms (buffer size 64 samples / 192 kHz) Digital Input/Output: Optical Digital Input: 2 systems Optical Digital Output: 2 systems Supported Digital Formats: ADAT/S/PDIF ADAT maximum number of input/output channels: 16 channels each for input and output.
