Microphone inputs. Your Quantum-series interface is equipped with 8/4 digitally
controlled PreSonus XMAX microphone preamplifiers for use with all types of
microphones. The XMAX design provides a Class A input buffer, followed by a dual-
servo gain stage. This arrangement results in ultra-low noise and wide gain control,
allowing you to boost signals without increasing noise. The ¼-inch front
panel inputs on Quantum can be either line or instrument. By default, they are set to
line. These inputs are not switching on the Quantum 2.
麦克风输入。你的Quantum系列接口配备了 PreSonus XMAX 8/4 数字控制的麦克
风前置放大器，适用于所有类型的麦克风。XMAX设计提供了a级输入缓冲器，其
次是双伺服增益阶段。这种配备会引起超低噪声和宽增益控制，允许你在不增
加噪声的情况下，增强信号。

Each analog input on the Quantum-series interface features a combo jack. This
convenient connector accepts either a ¼-inch phone plug or an XLR plug. Mic Inputs 3-
8/4 are located on the rear of the unit. Each input on your Quantum-series interface is
also auto-sensing. When an XLR is connected, the signal is routed to the preamp.
When aTRS is connected,the preamp is bypassed and the input signalis sent directly
to the ADC. When nothing is connected, Channels 1 and 2 on Quantum will default
to line inputs, Channel 3-8 will default to mic. All analog inputs on the Quantum 2
default to mic.
Quantum 系列音频接口上的每个模拟输入都有一个组合插孔。这个方便的接
口可以接受 ¼ 英寸电话插头或 XLR 插头。麦克风输入 3-8/4 位于设备的后面。

Instrument inputs. The ¼-inch TS connectors on Channels 1 and 2 are for use with
instruments (guitar, bass, etc.). When an instrument is plugged into the instrument
input, the mic preamp is bypassed, and the signal is routed to the instrument
preamplifier stage. Quantum users must engage the Inst button to use the
Instrument inputs.

Please note: As with any audio input device, plugging in a microphone or an instrument,
or turning phantom power on or off, will create a momentary spike in the audio output of
your Quantum-series interface. Because of this, we highly recommend that you turn
down the channel trim before changing connections or turning phantom power on or
off. This simple step will add years to life of your audio equipment.
