## 产品列表

### Apogee Ensemble (FireWire models)
```yaml
product: apogee-ensemble-firewire-models
brand: Apogee
price_gbp: null
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
bit_depth: 24
i_o_count: 36 channels simultaneous (8 analog I/O + ADAT + SPDIF)
sample_rate: 192000
phantom_power: 48V on mic inputs
number_of_preamps: 4
```

- **价格:** £None [^1]
- **概述:** The Apogee Ensemble (FireWire) is a 1U rack multichannel FireWire audio interface featuring Apogee converters, four digitally controlled mic preamps, eight analog inputs, ADAT and S/PDIF I/O, and support up to 192 kHz/24-bit. It includes Maestro routing/control and can operate in stand-alone converter mode, suited for Mac-based studios needing high-quality multichannel conversion.
- **最适合:** 适合紧凑便携的 FireWire 设置，因为它在单个 1U 机架单元中提供八路模拟通道、四个板载话筒前置放大器及 192 kHz/24-bit 转换。

### RME Fireface UCX
```yaml
product: rme-fireface-ucx
brand: RME
price_gbp: 1269.31
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
latency: 0.4 ms ADC / 0.15 ms DAC (converter latency); TotalMix direct monitoring down to 0.79 ms measured roundtrip at 44.1 kHz
bit_depth: 24 bit
i_o_count: 18 in / 18 out
sample_rate: 192 kHz
phantom_power: +48 V on mic inputs
number_of_preamps: 2
```

- **价格:** £1269.31 [^2]
- **概述:** Compact half-rack USB/FireWire interface with two digitally controlled mic preamps, four front instrument/line inputs and ADAT/SPDIF/AES digital I/O; supports up to 18×18 channels (44.1/48 kHz) and 24-bit/192 kHz conversion with RME's TotalMix FX and very low converter latency. Suited to mobile and project-studio users who need high-quality conversion, extensive routing and ultra-low latency monitoring in a small footprint.
- **最适合:** 由于为半机架、可采用总线供电（需外置电源）且提供 8 路模拟 I/O、2 个话放并完全支持 24-bit/192 kHz 及极低转换延迟，UCX 是最紧凑、便携的 FireWire 兼容 Fireface 接口之一。

### RME Fireface UFX
```yaml
product: rme-fireface-ufx
brand: RME
price_gbp: 2389.94
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
bit_depth: 24
i_o_count: 188
sample_rate: 192000
phantom_power: 48V
number_of_preamps: 4
```

- **价格:** £2389.94 [^3]
- **概述:** The RME Fireface UFX is a high-end multichannel USB audio interface offering up to 188 simultaneous I/O channels, 24-bit/192 kHz conversion, TotalMix FX routing/DSP and direct USB recording. It features multiple digital formats (MADI, ADAT, AES) alongside analog I/O and is built for professional studios and live facilities requiring large channel counts and reliable clocking.
- **最适合:** 不适合——其大规模 188 通道 I/O 和机架尺寸使其不适用于最紧凑的便携 FireWire 接口；适合需要高通道数、以台式/机架为主并需 USB 3/MADI 连接的固定录音室用户。
