APM5 V2/APM6 V2/APM8 V2 Owner's Manual

Active Studio Monitors

These active studio monitors create a new performance level in affordable studio monitors. Our unique design eliminates high frequency diffraction while providing full range monitoring accuracy, refined vocal reproduction, and enhanced bass response. The efficiency of our class D design is in excess of 90% with zero discernible hiss or white noise.

These APM V2 series monitors are compatible with most mixing scenarios. They feature various input connections so they hook-up to any mixing/monitoring system or media source (including RCA, balanced 1/4" TRS/XLR combo jacks, USB, 3.5mm Aux jack, and BT input). There is also an RCA line output for adding a subwoofer or additional speakers to expand your audio system.

Important Safety Instructions

To reduce the risk of electrical shock, do not remove amplifier plate. No user serviceable parts inside. Please refer to the rockville repair center for any repairs.

• Do not place these monitors on an unstable cart, stand, bracket or table. The monitor may fall, causing serious injury to a child or adult and serious damage to the unit.

• Do not use these monitors near water; for example, near a bathtub, sink, in a wet basement, or near a swimming pool.

• The monitors should be situated away from heat sources such as radiators, heat registers, stoves, or other devices that produce heat.

• These monitors should be connected to a power supply outlet of the same voltage as that which is specified on the amp plate of the unit. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where it exits from the unit.

• Clean only with a soft damp cloth. Unplug this product from the wall outlet before cleaning.

Monitor Placement and Room Interaction

By design, near-field monitors minimize room interaction. Unlike conventional stereo setups or large studio monitors—where sound reflections from walls, ceilings, and floors can greatly alter audio quality—near-field monitors shorten the listening path to your ears.

The APM V2 series active monitors provide excellent flexibility by reducing sensitivity to room conditions. Additionally, their adjustable high and low frequency controls allow you to fine-tune the sound and compensate for irregularities in the listening environment.

Low Frequency Behavior

• Placing monitors close to a wall or corner will reinforce bass response.

• Positioning them 2–3 feet away from walls or corners will reduce low-frequency buildup.

Optimal Placement Guidelines

• Ensure monitors are positioned so that the listening area is fully covered.

• All monitors should be aligned on the same horizontal plane.

• For testing and break-in, we recommend using acoustical music, as it provides a wide and natural frequency spectrum.

Triangular Listening Setup

• Begin placement by measuring an equilateral triangle (all three sides equal).

• The apex of the triangle should be at the listening position.

• Position the left and right monitors at 60° angles, equidistant from the listener (see diagram below).

Subwoofer Placement and Setup (Optional)

Subwoofer placement will vary depending on the size and shape of your room, so some trial and error is usually required. When adding a subwoofer to the APM V2 series, finding a good location for maximum efficiency from the sub will depend on the available settings on the subwoofer. Please read the subwoofers manual for settings that will best compliment the APM V2 series speaker system. Use the diagram below as a starting reference.

Amplifier Functions

1. Center detented treble control

2. Center detented bass control

3. Line In RCA jacks

4. Line Out RCA jacks (post-volume, post-bass, and post-treble)

5. 3.5mm input jack

6. USB 2.0 input port (will display on your computer as APM5 V2, APM6 V2, or APM8 V2 depending on the model you've purchased).

7. AC power input

8. Power switch

9. Two Combo XLR and 1/4" TRS inputs: These inputs accept a wide range of balanced signals from a variety of sources such as keyboards, electronic drums, tape recorders, mixers, etc. When you use an unbalanced 1/4" TS plug, the line input automatically turns the ring into ground.

10. Output to left speaker

Front Panel Functions

The APM V2 series is equipped with a multifunction control knob featuring an LED ring on the front of the right speaker. Rotate the knob left or right to adjust the volume, and press the knob to switch input modes. Each mode is represented by a distinct LED color displayed around the knob: Power-up (red), Bluetooth (blue), USB (green), AUX (purple), XLR/TRS (white), and Line In (yellow). When the speaker is powered down, it will remember the last input setting. When powered-up, the unit will be in that setting.

Passive Speaker

At the rear of the passive speaker you will find the input port to connect the cable from the right speaker.

Bluetooth Operation

Before you start: Make sure your phone/tablet/computer has Bluetooth enabled.

1. Turn on the speaker and press the Volume/Mode multifunction knob to cycle modes until the LED ring is blue.

2. On your external device, open Bluetooth settings and ensure the device is discoverable. From the list of available devices, select APM5 V2, APM6 V2, or APM8 V2 depending on your model.

3. When pairing is successful, the LED ring will stop flashing and remain solid blue.

4. Control playback volume on your device or on the speaker—the controls are synced.

5. Please note, if you switch the speaker mode or turn it off and back on, it will remember the last paired device. To disconnect a paired device, press and hold the Volume/Mode multifunction knob.
