Description
The Tascam US-366 USB audio interface is made for professionals, and offers a combination of 4 in and 6 out, or 6 in and 4 out with its unique I/O structure. The US-366 also features an on-board DSP mixer with high-quality DSP effects perfect for sweetening any project.
High-Quality HDDA - High Definition Discrete Architecture - Mic Pre-Amplifiers
To ensure superior sound, TASCAM organized months of tests and trials to design the HDDA mic pre-amplifier. Manufactured with a discrete structure and select premium parts, the HDDA pre-amp achieves a wide frequency response (10Hz to 68kHz), high S/N ratio, low noise and low THD+N.
Up to 192kHz/24bit Recording
In the process of creating music, many engineers have started utilizing high-resolution formats while recording to ensure the best quality sounds. The US-366 is suited perfectly for these high-quality minded recordings. (Included CUBASE LE can not record by 192kHz)
Two XLR/TRS (MIC/LINE) Inputs with Full +48V Phantom Power Supply
The US-366 is designed with two XLR with +48V phantom power and two TRS inputs. Having both options for condenser mics and line level inputs ensures you are getting the best possible sound and lowest-noise when recording. In addition, INPUT-1 can connect any high-impedance equipment directly, like a guitar.
DSP Mixer Designed for Music Creation and Podcasting
The DSP mixer function provides a multi-track mode and a stereo-mix mode.
Multi-track Mode
The multi-track mode is ideal for music creation. This mode delivers independent monitor-mixing from a send-level like an inline-console to a PC. In addition, this mode delivers monaural-monitoring.
Stereo-mix Mode
The stereo-mix mode makes podcast recording or broadcasting convenient and easy. An output audio signal from any PC can relay that signal back to the PC again via your DSP mixer. Any BGM from a PC can mix your voice by microphone then the mixed sound will transfer back to the PC again.
Onboard Effects Supports High-Quality Recording (Send Effects and Insert Effects)
The US-366 is designed with on-board effects such as compressor, 3-band EQ and Reverb all located on-board the DSP. While recording, you can use the input effects for any input signal and the reverb effect on any monitoring signal at the same time. (DSP effects can use on 44.1/48kHz operating)
Insert Effects
The input effects can be selected from compressor or 3-band EQ. Input effects can use various recording. For example, while recording vocals you can boost your high-frequency range with the 3-band EQ. Also, the compressor effect is very convenient at recording especially for bass guitar, vocal and drums.
Send Effect
The send effect include just reverb. The reverb effect is necessary articles at recording. Monitoring sound will get wet-sound by this reverb effect, but a send-sound to a PC keeps just dry sound.
Dedicated MIXER PANEL Button Recalls The DSP Mixer with One-Click
The US-366 is built with a "MIXER PANEL" button located conveniently on top. This button provides a one-click recall function for the DSP-mixer. When pushed a second time the mixer panel will be conveniently hidden.
LINE 3-4 Analog Connectors - Select Between Input or Output, Up to Six Inputs or Six Outputs
The US-366's LINE 3-4 connectors can be selected between input and output to customize TASCAM's US-366 to any recording environment. When "INPUT" is selected, you can connect an abundance of line-level audio devices. When selecting "OUTPUT", connect to devices such as multiple headphone amplifiers. This system provides dedicated monitoring management for each player. (When operating on 192kHz, LINE 3-4 connectors outputs same signal as digital output.)
Coaxial/Optical Digital Inputs/Output
The US-366 has two types of digital input/output connectors (RCA Coaxial and TOS-link Optical). Two outputs can transmit the same signal at the same time but when input is selected, only one connector is available at a time.
