+4/-10dB output level switch

+4/-10dB output level switch

Used to select the output level to allow compatibility with professional and consumer products with varied input sensitivities.

Two independent headphone amplifiers

Two independent headphone amplifiers

Each with its own volume control

Dim switch

Dim switch

Activate this switch to decrease the level of the outputs by 20db. The DIM feature effectively reduces the output signal and therefore the listening level to allow discussion in the control room without having to change the position of the volume knob.

Mono switch

Mono switch

Activate this switch to listen to the audio outputs in monophonic mode. This combines the stereo audio signal into a monophonic signal, which is useful when checking for any phase cancellation issues in the stereo signal.

Volume control

Volume control

As it is an ACTIVE device, the ACTIVE-1’s Volume control, controls an electronic circuit, which in turn adjusts the level of the audio going through the device, providing gain increase as well as attenuation.

Talkback switches and volume

Talkback switches and volume

A built-in talkback microphone, can be routed to the headphone outputs or the 2TRACK outputs. When the Talkback function is engaged, the Control Room output signal is attenuated by 20 dB.

Monitor select switches

Precision control

The M-PATCH ACTIVE-1 accommodates four input sources (3 x stereo analog and 1 x USB) and three stereo analog outputs plus USB. In addition to the core functionality of providing seamless A/B switching between input signals and output speaker monitor systems, the ACTIVE-1 delivers a full complement of audio monitoring functions, including precision volume control, mono summing, mute, and dim (ducking). A handy footswitch-activated talk-back function, complete with on-board condenser microphone and selectable routing, has also been integrated, making the ACTIVE-1 the ideal low-cost solution for a broad range of studio production applications. Designed to provide the lowest-noise operation possible in an active monitor controller, the ACTIVE-1 is ideal for applications where both signal attenuation and boost is needed. In addition to the feature complement found on the PASSIVE-1, the ACTIVE-1 also includes LED level metering and convenient switch-selectable +4dBu/-10dBV input stage operation. The ACTIVE-1 features on-board USB, allowing for direct digital audio recording and playback when used with a computer DAW. The USB output mirrors the signals appearing at the analog 2 Track outputs, while the computer’s L/R output feeds the USB in. Housed in a sturdy metal chassis and fitted with a durable array of switches and secure connectors, the ACTIVE-1 is built to provide years of worry-free operation.
