Introduction, KEY Features | Mackie UP4161, UP4121, UP4061 specs

2. INTRODUCTION

The UP4000 Series Power Amplifiers are designed for continuous duty in speech, music, paging, and sound reinforcement applications in churches, schools, offices, and other venues demanding high performance, flexible features, and rugged dependability.

Two discrete inputs with priority are provided. The main program input is actively balanced and terminated to a barrier strip connection on the rear panel. The second input is unbalanced and terminated to a single RCA connector. A contact closure will give priority to the balanced input by muting the unbalanced input. The unbalanced input features a parallel output and 0 dB/20 dB sensitivity switch.

Output modes include 4Ω constant impedance and 25V, 50V, 70V, and 100V constant voltage. The smart output stage is fully protected against permanent damage caused by overloading, shorts, and extreme temperatures. Activation of the overload protection circuit turns on 18 VDC (300mA) power at a barrier connector on the rear panel, which may be used to drive a relay or indicating LED. The UP4000 Series will operate on either 115 VAC or 230 VAC, 50/60Hz, as determined by the Voltage Selector switch, and supplied by a detachable IEC power cord. Insulated terminals to connect a backup 24 VDC battery are provided on the rear panel. Switchover to DC is automatic. A programmable stand-by mode allows the amplifier to be turned on remotely with a contact closure.

The front panel provides a Master volume control, and Low and High EQ controls. The control knobs can be removed for security, and their recessed shafts covered with the supplied inserts. LEDs indicate power, stand-by mode, signal present at the output, peak, and output overload. 12 dB/octave Low and High shelving equalization with up to 12 dB of boost or cut at 100Hz and 10kHz can be applied to the output signal.

Accessories include a rack mounting kit.

The presence of individual channel gain control and a -20dB pad provides versatility, allowing users to manage a wide array of sound sources, from soft vocals to loud instruments. Additionally, the device integrates seamlessly with various Digital Audio Workstations (DAWs), making it an ideal choice for recording studios.

The UP4121, on the other hand, is tailored for applications requiring fewer channels without compromising quality. This 12-channel preamp shares many features with the UP4161, including the robust 96kHz/24-bit A/D conversion technology. The UP4121 is equipped with advanced metering for each channel, ensuring that audio levels are monitored accurately, preventing clipping and distortion. Its lightweight design enhances portability, making it suitable for both studio and live settings.

Finally, the UP4061 rounds out the lineup with its 6-channel configuration, perfect for smaller productions or personal use. Despite its compact size, the UP4061 does not skimp on features, offering similar performance specifications that are consistent with its larger counterparts. It utilizes high-performance analog circuitry and delivers rich tonal quality, making it suitable for both powered speakers and passive monitors.

All three models feature Ultra-low noise, which minimizes self-noise, ensuring that recordings are clean and professional. The high-quality components and durable construction mean that these preamps will withstand the rigors of regular use, making them indispensable tools for audio professionals.

In summary, the Mackie UP4161, UP4121, and UP4061 are versatile audio solutions that cater to a variety of needs, from expansive studio recordings to intimate live performances.
