Setting up the Resolv 40a

Background on the Resolv 40a Studio Reference Monito

The Resolv 40a is a near field reference monitor featuring a custom designed, 4^ copolymer, low frequency driver and a 1^ treated textile tweeter, employing a Ferro fluid cooled voice coil and neodymium magnet. The monitor's crossover has been carefully designed with high quality components insuring a linear frequency and phase response. The Resolv 40a enclosure is constructed from MDF (Medium Density Fiberboard) and is finished in scuff resistant, textured paint. The monitor's enclosure also includes a tuned vent port that provides extended low-end response, and with a low turbulence design, the low frequency driver can move freely with minimal effect on the overall impedance. On the rear of one enclosure you'll find Resolv 40a's control panel, which features an RCA unbalanced input. This input is connected to Resolv 40a's internal stereo power module providing 25 watts per channel through passive crossovers

Positioning the Resolv 40a

Near field monitoring has become the choice of many engineers in large and small studios because it minimizes the effect of room acoustics. This is especially important in today's project studios since the budget for room acoustics is often close to nothing. By positioning the reference monitors in the near field (close to the listeners), you can greatly reduce the effects of room acoustics. The most important considerations when evaluating the effects of room acoustics are reflective surfaces that are around the monitoring area. These can include flat tabletops, glass mirrors or framed pictures, large open walls and even the surface of your mixing console. Mostly all reflecting sound will eventually reach the listening position, but since it is slightly delayed from the direct source, the result is random cancellation of some frequencies, or comb filtering. If possible, remove any and all reflective surfaces. You may also want to hang some acoustic foam on walls that are close to the monitors. When positioning the monitors you'll want to set up what is commonly referred to as the "mix triangle". In this ideal configuration, the space between the left and right monitor is equal to the distance from the listener to each monitor, forming an equilateral triangle. (Figure 1.)

Prime Listening Spot

Setting up the Resolv 40a

Positioning the Resolv 40a - continued

Speaker Orientation

The Resolv 40a's can be used in either the vertical or horizontal position. When using the monitors in the horizontal position, be certain to place the left and right side tweeters on the outer most sides. (Figure 2) This will improve the stereo imaging and bass response by increasing the coupling of the low-end drivers

Figure 2.

A Moment of Reflection

When choosing the height of your monitor system, be careful to avoid reflections off the surface of the mixing console. (Figure 3.) These reflections arrive at the listening position slightly delayed from the original sound resulting in strange cancellations and overall unpredictable response. Visualize straight lines representing the beams of sound radiating from the monitors and choose a height that reduces the occurrence of reflections that will end up in the prime listening spot. (Figure 4.) In most cases, the ideal position is slightly behind and above the mixing console's meter bridge

Connecting the Resolv 40a

Resolv 40a Quick Connections

Note: Before plugging in and turning on, remember the "LAST ON FIRST OFF" rule of power amplifiers (and power monitors). When powering up your system, be sure that all the wires are connected, turn your mixer and any other out board gear on, and then last turn your Resolv 40a's on. When powering down, turn your Resolv 40a's off first and then your mixer and outboard gear

The Resolv 40a connections can be made via the rear panel RCA Inputs. Follow the simple steps and diagram below for a quick connection using a standard recording console's control room outputs

Using the included 18-gauge Extension Speaker cable, connect the negative side of the wire to the Black terminal and the positive side to the Red terminal on the Right-side monitor.
Now, connect the Negative side of the wire to the Black terminal and the Positive side to the Red terminal on the Left-side monitor.

Note: Just about all un-shielded speaker wire will have a marking indicating the negative side. To avoid phase cancelation problems, be sure to maintain the correct connection for the positive and negative sides throughout your system

• Lower your mixer's master outputs to all the way off.
  Connect the mixer's left Control Room output to the stereo input on the Right-side Resolv 40a .
• Set the Resolv 40a's input Volume control to the 2 o'clock position.
• Run an audio signal (like some music from a CD) through your mixer and raise the Control Room level to a comfortable listening level.

Operating the Resolv 40a

Resolv 40a Rear Control Panel

The Resolv 40a's rear control panel is where you will make your connections for both AC power and audio signals. The following section details the rear panel controls and connections

Powering the Resolv 40:

Since the Resolv 40a is an active studio monitor with an on-board power amplifier, it is necessary to connect the unit to an AC power supply. Make sure that the main Power switch is set to the off position and connect the supplied IEC power cable into the AC inlet.

Things that go Hum!

When running power cables, be careful not to run the AC power cords or AC extension cords in parallel to your input cables. This will help reduce any AC hum that can be picked up. If your have to cross an AC line with an audio line, try to cross them at a 90 degree angle for the least amount of induced hum.

1 POWER SWITCH - The POWER switch is used to turn on the Resolv 40a's active electronics. When set tc

the on position, the front panel blue LED illuminates, indicating the Resolve 40a is powered up and ready for operation.

The Ins and The Outs

The Resolv 40a features a stereo pair of input connectors providing easy installation with a variety of audio devices like recording consoles, hard disk recorders, CD players and computer sound cards, to name a few. The following section details the Resolv 40a's input connectors. In addition, there is a detailed cable-wiring diagram on page 12.

RCA AUDIO INPUT - The RCA input accepts unbalanced signals used to connect signals from unbalanced -10dBV devices.
TERMINAL CUP - Push Terminals for connecting the Left-side Extension Speaker.

VOLUME CONTROL - (FRONT PANEL)

The volume control is used to adjust the overall output level of the Resolv 40a. When operating the unit for the first time, start with the volume control set all the way off. Slowly raise the Volume control to reach a comfortable listening level

Connecting to the Resolv120a Subwoofer

Resolv 40a with Mono Sub

Adding a subwoofer and extended low frequency response to your Resolv 40a system is easy using the Resolv 40a's LINE _EVEL inputs. Below is a typical system set-up using the RESOLV 120a with a mixer and a pair of Resolv 40a's satellite speakers. The Resolv 40a's inputs utilize industry standard RCA connectors. For a detailed wiring diagram, see the section 'Resolv 40a Connections" on page 12. Follow the steps in the diagram below to set up your system.

Lower your mixer's master outputs to all the way off.
Connect the mixer's left output to the RESOLV 120's LEFT LINE INPUT and the mixer's right output to the RESOLV 120's RIGHT LINE INPUT. Now connect the RESOLV 120's LEFT LINE OUTPUT to the left input of the Resolv 40a, and the RESOLV 120's RIGHT LINE OUTPUT to the right input of the Resolv 40a
Run an audio signal (like some music from a CD) through your mixer and raise the level to a comfortable listening level.
Now adjust the SWEEP control to the desired frequency. Consult your studio monitors owner's manual for a recommended crossover point. You can also use your ears by adjusting the SWEEP control to the frequency that sounds good to you. A good place to start is about 70Hz
