Frequently Asked Questions - ACUMEN 8A PHONIC

How do I set the volume on the Acumen 8A?

Use the input sensitivity control on the rear panel. Turn it clockwise to increase volume, counter-clockwise to decrease.

How do I adjust the high frequencies?

Use the HF control on the rear panel. It adjusts frequencies between 8 kHz and 20 kHz by ±3 dB. Turn left to cut highs, right to boost.

Can I mount the speaker horizontally?

Yes, the Acumen 8A can be used horizontally. For stereo pairs, place the HF drivers on the outer edges for best stereo imaging.

What voltage does the Acumen 8A support?

It has a voltage selector switch for 115VAC (100-120V) or 230VAC (220-240V). Always check local voltage before use.

How do I clean the speaker?

Use a dry cloth only. Do not use aerosol or liquid cleaners. Unplug before cleaning.

What inputs does the Acumen 8A have?

It has balanced XLR and 1/4" TRS inputs, plus unbalanced RCA inputs. All operate in parallel.

Does the speaker have protection circuitry?

Yes, it includes driver overload protection, thermal overload protection, and electronic speaker protection to prevent damage.

What is the warranty period?

Phonic offers a minimum of one year from original purchase date against defects in materials and workmanship. Retain your dated sales receipt.

Can I repair the monitor myself?

No, do not attempt self-repair. It voids the warranty. Contact your local Phonic distributor for service and repairs.

How should I position the monitor for best sound?

Place the speakers at ear level, forming a 60-degree angle at the listening position. Avoid close proximity to side walls to reduce reflections.

INTRODUCTION

Congratulations on your purchase of another great product from Phonic. The bi-amplified Acumen 6A and Acumen 8A are two-way active monitors designed for high output and unsurpassed clarity.

The Acumen 6A offers a 6" woofer and 73 Watts of power while the Acumen 8A is an 8" model with 100 Watts of power. The paper cone woofers offer extended low frequency response and higher output level.

The Acumen's compact size, excellent dispersion and precise stereo imaging make it ideal for near field monitoring, mobile vans, broadcast, TV control rooms and home studios.

Designed as an active speaker, this unit contains drivers, power amplifiers, active crossover filtering and protection circuitry. The directivity control system used provides excellent frequency balance even in difficult acoustic environments.

CROSSOVER

The active crossover network consists of two parallel band pass filters. Acoustically the filters are complementary and the slopes are 24dB / octave. The crossover frequency is set to 1.7kHz.

AMPLIFIERS

The amplifier unit is mounted to the rear panel of the speaker with damping material, to ensure rattle free operation and long term reliability. The unit incorporates special protection circuitry as well, for driver overload protection and amplifier thermal overload protection. Variable input sensitivity allows for accurate level matching to the mixing console.

MOUNTING THE MONITOR

Vertical / Horizontal Mounting

The speakers are normally delivered for vertical mounting. Designed for near field monitoring, this studio monitor requires shorter distance than traditional monitors from its location to your ears, which means the reverberation time and general acoustics of the listening room are less critical. Hard surfaces will, however, reflect the higher frequencies, therefore try to avoid putting this monitor close to side walls.

The control surface of your mixing console may also pose a problem. To minimize control surface reflections, position your monitor as shown in the figure below, using the meter bridge or rear panel to block sound from both drivers reaching the control surface. Make sure that there is nothing between your ears and the speakers.

If your console has no meter bridge, try positioning the monitor higher or further behind the desk. Active series is designed to be used in both the upright and horizontal position. If you want to place two Active series horizontally, it is recommended you put the HF drivers on the outer edge. The low frequencies of this unit will generally sound better if the cabinet is against a wall. If possible, provide a rigid surface (eg. shelf) that is separate from the mixing console and other equipment. The speakers should roughly form a 60 degree angle at the listening position, and should be angled towards the listener.

Console Top Mounting

If the active studio monitor series are used for console top mounting, it is recommended not to mount the speakers directly on the console; instead, position the speaker slightly behind the console by using floor stand or wall mount behind the console. This prevents the reflection from the console surface from coloring the sound.

INSTALLATION

Each active studio monitor is supplied with an integrated amplifier unit, a mains cable and an operating manual. Once unpacked, place the loudspeaker in its required listening axis. Before connecting up, ensure that the mains switch is off.

Audio input is made via a balanced XLR and 14 " TRS phone jacks, which operate in parallel. Once connection has been made, the speakers are ready to be powered-up. Before turning the unit on, make sure the mains needed is identical with the AC outlet.

Setting the Volume

Adjustment of the volume of each speaker can be made to match that of the mixing console or other source, by using the input sensitivity control on the rear panel. Turning the control counter-clockwise will reduce the level and clockwise will boost the signal.

Setting the HF Control

The acoustic response of the system may also have to be adjusted to match the acoustic environment. The adjustment is done by setting the HF control on the rear of the speaker. This will adjust high frequencies on a curve between 8KHz and 20KHz, resulting in an overall boost to high frequency sounds. Set rotary control to the left to cut high frequency sounds, and to the right to boost them.

OVERVIEW

1. Volume Control

This rotary control allows users to adjust the input sensitivity of the Acumen.

2. HF Control

This control adjusts high frequency audio between -3dB and +3dB.

3. Input Connectors

The balanced 14 " and XLR inputs are available for users to connect various output devices to the Acumen studio monitors. In addition to these inputs, the Acumen also features an unbalanced RCA input connector.

4. Voltage Select Switch

This switch allows you to adjust the operating voltage of the Acumen between 115VAC and 230VAC. When set to 115VAC, the Acumen can be used with voltages between 100V and 120V. When set to 230VAC, any voltages between 220V and 240V. Please be sure to check your local voltage levels before using the Acumen speaker.

5. Power Switch

This switch allows users to turn the Acumen on and off.

6. AC Power Connector

This AC power connector is for a suitable AC power cable. Connect the power cable to a suitable AC power source. Be sure to check the local voltage levels and the voltage select switch before use.
