Setup

Installation

CAUTION: Before you begin, make sure your mixer amplifier is unplugged from the power source, the power switch is in the “OFF” position, and all volume controls are set to minimum level (turned counterclockwise).

Location:

Take the unit out of its packaging (keep it for any return to the workshop). The PR-130BT and PR-240BT mixing amplifiers can be installed in a standard 19” equipment rack or on a shelf. To install the unit in a standard 19” equipment rack, please use the rack ears that are included with the unit. Do not mount mul�ple units directly on top of each other, allow a 2U space between the units for convection cooling. If a table or shelf installation is the chosen route, be sure to choose a flat surface, with 12-inches (about 30cm) of air space around the unit for convection cooling, and that is free of liquids or other such hazards.

To select an appropriate location for your equipment, you must consider the distance between the mixer amplifier and the speakers, the need to access the equipment to change the source or adjust the volume, the proximity of the sockets electrical, etc. You must determine the length of the cables used to connect your equipment to the speakers. Depending on the type of loudspeakers and the length of the cables, you can choose to route the signals to the loudspeakers in low impedance or in constant voltage.

If you are using low impedance speakers, you must connect them to one of the low impedance outputs (4 ohms) of the mixer amplifier with speaker cables. However, pay attention to the diameter and length of the cables. If you are using loudspeakers with built-in 70V transformers, often referred to as constant voltage systems. The advantage of these systems is that they allow the use of long cables to connect several loudspeakers to the same amplifier. The PR-Series mixer amplifiers are ideal for this type of application as they are equipped with 70/100V output transformers.

Using the rack ears

How to attach the rack ears.

  1. Locate the two rack ears and four rack-ear screws supplied.
  2. Place a rack-ear flush with the right front of the chassis.
  3. Insert a screw into the bo�om hole of the rack-ear and chassis. Screw it in.
  4. Insert a screw into the top hole of the rack-ear and chassis. Screw it in.
  5. Repeat steps 2 to 4 for the le� side of the chassis.
  6. Remove the four legs from bottom of unit.
  7. Please refer to Figure 2.1

Instruction

Speaker selection
When selecting loudspeakers, you must consider a few important factors, such as the location of the mixer amplifier, the type of loudspeakers and the need to use a 70V distribution system. The following sec�ons explain how to connect loudspeakers or a constant voltage system in a typical installation.

Using passive speakers

Before using low impedance speakers (4 or 8 ohms), you must first determine the location of your mixer amplifier. If the speakers are less than 30 meters away, you can connect the amplifier directly to the speakers in low impedance mode. Be sure to check the impedance of the speakers. The 4 Ohms output allows you to connect a 4 Ohms speaker or two 8 ohms speakers in parallel. If the speakers are more than 30 meters away (approximately), it is best to use a constant voltage system. Using a constant voltage system If your setup has many loudspeakers and long cables, you might consider using a 25 or 70V constant voltage system.

This type of system became standard in the field of installa�ons in the middle of the 20th century because it offered an efficient solution for the use of multiple enclosures and long cables. It is inspired by long distance electrical networks which use increased voltage and reduced current to carry very high power over long distances with more affordable and rela�vely small diameter cables. The voltage is then reduced and then routed to the consumer on a short, large diameter cable.

The same principle applies to constant voltage audio systems. A transformer connected to the output of the amplifier increases the voltage and reduces the output current, allowing the use of long, smaller-diameter cables to link multiple speakers with step-down transformers. For economy, the 70V standard was adopted in the United States because electrical conduit is required on lines with voltages greater than 100V peak-to-peak. Commercial sound systems, such as those installed in schools, office buildings and restaurants, o�en use a constant voltage distribu�on system when multiple loudspeakers are connected in different areas.

Many loudspeakers with transformers are produced by various manufacturers. Most of these loudspeakers provide tap points on the transformer to allow power to be distributed to the loudspeakers and their levels to be adjusted separately. Quest Commercial mixer amplifiers have a built-in transformer to step up the output voltage and step down the current so that multiple speakers (with transformers) can be connected using long cables. Constant tension systems allow the use of cables from 1 to 1.6 mm in diameter, depending on their length (long cables must be larger in diameter).

A simple way to represent a constant voltage is to divide the power in Watts of the amplifier by the number of loudspeakers used. For example, to connect ten loudspeakers to the output of a PR-130BT amplifier, use a loudspeaker whose transformer provides a tap point of approximately 10 Watts. 130 Watts divided by 10 speakers gives 13 Watts per loudspeaker, but we must always keep a cushion of about 15 to 20% of the power of the amp to make sure not to overload the amp.

Typical ceiling speaker with onboard transformer and six power taps. These power taps also control volume level for sound balancing.

Connections

Connecting speakers
Connect the speakers to the terminal block output connectors on the rear. Never turn on the amplifier when the speakers are not connected to the outputs. When using the 4 Ohm output, you must connect speakers with aminimum impedance of 4 Ohms (4 Ohms or more).

For 70V operation, connect the speaker’s positive input to the 70V terminal, and the negative input to the COM (ground) terminal. Then connect the other speakers one a�er the other in parallel.
Connections

Since the PR-Series mixer-amplifiers have 6 output zones in 70V operation, you can create separate audio environments using up to six of the PR-Series’ outputs.
[ Figure 2.3 speaker output connectors]
Connections

Connecting sound sources
Then connect the sound sources to the terminal block input connectors on the back. If your console or source has Balanced outputs, use balanced three- conductor connections and connectors (you can use unbalanced connections, but you’ll get better sound quality and less noise if you use balanced connections).

Set all input level controls (on the front) to minimum (“-MIN“). Then connect the mains lead to a grounded outlet.
[ Figure 2.4 Connection example ]Connections

Wiring guide
Choose the input connector and the appropriate cable for each source.
We recommend the use of pre-assembled or professionally assembled 22-to-24-gauge balanced cables.
Figure 2.1 shows the connection diagrams for the different connectors. RCA input connectors can also be used as unbalanced inputs.
Connectors

Connect microphones or balanced line-level sources to the balanced inputs of the mixer amplifier. Adjust the Gain accordingly. Connect unbalanced line- level signals to RCA connectors.

Choose the output connector and the appropriate cable for each source.

For the amplifier output connectors, we recommend the use of pre-assembled or professionally assembled speaker cables of high quality and of sufficient gauge. You can use pluggable terminal blocks for your output connectors. To prevent the possibility of shor�ng, wrap or insulate exposed speaker connectors. Using the guidelines below, select the speaker wire gauge based on the distance between the amplifier and the speakers. Wire gauges apply to 4-ohm output.

Distance Recommended Gauge
Up to 25 ft. 16 AWG
26 ~ 40 ft 14 AWG
41 ~ 60 ft. 12 AWG
61 ~ 100 ft 10 AWH
101 ft ~ 150 �. 8 AWG
151 ~ 200ft 6 AWG

[Table 2.1 Recommended speaker wire gauge for 4-ohms opera�on]

NOTE: Custom wiring should be performed by qualified personnel only. Class 2 wiring is required.

Wiring guide – Continued

CAUTION: Never use shielded cable for speaker output.

Maintain correct polarity on output connectors.

For each output channel, connect the output terminal block connector to the speakers.

Use terminals marked COM and 4Ω / 8Ω for low impedance speakers, or use terminals marked 70V or 100V, and COM for high impedance speakers.

Connect the COM terminal to the nega�ve (-) terminal of the speaker; connect one of the other terminals to the posi�ve (+) terminal of the speaker.

Output impedance and voltage are as shown in Table 2.2

PR-130A/130BT 451 / 22V 8352/ 100V
PR-240A/240BT 452 I 31 V 4252/ 100V

[Table 2.2 Output voltage and impedance]

NOTE: The impedances listed in Table 2.1 represent the total impedance of all speakers connected.
CAUTION : Never use both the Low-Z (4 ohms) and Hi-Z (70V or 100V) terminals at the same time.

Operations

Signal input gain control
The PR-Series mixer-amplifiers can accept balanced mic or line input signals, thanks to the gain selec�on switches (figure 3.1).

Phantom power
The PR-Series mixer-amplifiers can supply 48V DC phantom power to use condenser microphones on any of the mic channels. To use phantom power, please set the switch to the PH position (figure 3.1).

VOX Priority / Ducking
The PR-Series mixer-amplifiers offers a MIC priority / Vox feature for input 1-4. When set to on, this slide
switch configures mic channels 1-4 to mute the other input channels when a signal is present on the connected microphones. The level at which an input will mute the other ones can be adjusted by the LEVEL volume.

Priority Control
The PR-Series mixer-amplifiers have a three (3) layer priority mute function. When a higher priority source is activated, other input signals are muted except the sources on the same priority level. Tele-Paging > RM6 > Mic/line 1-4 > Media Player (if present) > AUX1~2

User message recording and playback
The PR-Series mixer-amplifiers have an internal memory for recording and playback of a simple message.
You can record and playback a message of approximately 60 seconds. This message is recorded and played via contac closure on the rear panel. The message can be sent to a specific zone but selec�ng the zone prior to activating the contact closure.

Remote Microphone
A RM6 remote paging microphone station can be connected to the PR-Series mixer-amplifiers. The RM6 remote microphone station can select from the 6 individual zones and play a pre-announcement chime. The RM6 remote microphone station should be connected using UTP CAT5/6, CAT6 is recommended for longer distance. Up to four (4) RM6 remote microphone stations can be daisy-linked using the Link port. The maximum distance between the RM6 remote microphone station and the PR-Series mixer-amplifier is 200m.
Operations

Using Music on Hold (M.O.H.)
The PR-Series mixer-amplifiers include a MOH (Music on Hold) function allowing you to connect the PR Series to a business telephone system. With MOH, when customers call in to the business and are put on hold, they hear background music from an external source or from the internal media player if the optional BMP-1 (Bluetooth, tuner, and Media player module) is installed. You can make the call-in experience more pleasant or take advantage of valuable time by playing a pre-recorded commercial message using MOH

You can set the volume of the MOH signal using the MOH Level control.

Using the TELE-Paging function

Using the TELE-Paging function You can connect the PR-Series mixer-amplifiers to a business telephone system using the TELE PAGING connector allowing announcement paging from any telephone. Usually, the telephone system provides a dedicated output and has the ability to send a page using a certain extension number.
