Introduction

The MRZ-6 Line Level Multi-Room Controller combines with the Niles SI-1230 twelve channel power amplifier to enable you to individually adjust the room volume of up to six rooms. One source is fed to all of the rooms from the record output, preamp output or second zone output of any preamp/receiver. Six MRZ-6 systems can be interconnected in single or multiple zone configurations (up to 36 rooms). Each group of six rooms (one MRZ-6) can be powered by a single Niles SI-1230 twelve channel power amplifier or by any mix of conventional power amplifiers.

By using optional Niles remote controls, keypads or the front panel of the MRZ-6, you may control room volume, local room on/off and global system commands (CD All On, Tuner All On and All Off). On the unique Niles RP-9 keypad two buttons (labeled CD and Tuner) offer one touch intelligent operation; a single touch turns on the preamp/receiver, selects the correct input and issues one additional IR command (to play the CD or select your favorite radio station). IR sensors (using hand-held learning remote controls) or Niles IntelliPads are also capable of one touch automation and can offer full control of up to six sources.

Features and Benefits

Audiophile Quality Independent Line-Level Volume Control

The ultimate in sound quality for every room in the house. Each room is independently adjusted for volume via one of the six built-in volume controls. Unique digital line-level gain circuits provide 136dB of dynamic range in 1dB increments with distortion and noise specifications that are unbelievably low when compared to conventional circuitry. The MRZ-6 multi-room system makes no compromises in audio performance.

Never Disturb Others

The MRZ-6 ROOM ON/OFF and VOLUME UP/DOWN commands enable you to control the room you are in without affecting the rest of the system. You can fine tune your listening area without disturbing others in another room. Of course, if you turn on the system, only the room you are in turns on. The rest of the house stays muted until music is desired in another room.

A Single Touch Turns On All of Your Favorite Rooms

All of your favorite rooms can be turned on instantaneously by pressing and holding either the CD or the Tuner buttons for more than two seconds. Switches on the rear panel of the MRZ-6 enable you to individually choose which rooms turn on when the ALL ON command is received (so that the baby’s room does not turn on when you are entertaining).

A Single Touch Turns Off Your Entire System

Pressing and holding the On/Off button on a keypad or a remote control will turn off

all

rooms and turn off your preamp/receiver, CD player and other components. You will never worry if something is still on when you go to bed or leave the house.

One Touch Automation For CD and Tuner With the Niles RP-9 Keypad

The RP-9 keypads have two keys labeled “CD” and “T uner”. When the CD button is pressed, the MRZ-6 intelligently “checks” to see if your preamp/receiver and CD player are on or off. If they are off, the MRZ-6 turns them on. Then after it “knows” that the components are on, it selects the CD as the source and issues the “Play” command (a two step macro). Likewise, when you press the Tuner button, the system is configured for you to listen to radio (another two step macro).

This is accomplished by teaching the MRZ-6 the “power” command (or separate “on” and “off” commands), the “CD” and “Tuner” input commands for the preamp/receiver; one additional command for the CD player (typically “play” or “random-play”) and one additional command for the Tuner (some tuners respond to a single numeric command by recalling a favorite radio station).

One Touch Automation and Full Source Control for up to Six Components with the Niles IntelliPad

The Niles IntelliPad provides intelligent turn on and ten step macros for up to six sources. The sour ces are custom labeled on six backlit keys. Additionally, after a source has been selected, the right hand buttons of the IntelliPad offer full control of the selected source (i.e. play, stop, pause, disc skip up, disc skip down, track skip up and track skip down) and volume up, down and mute.

One Touch Automation and Full Source Control via Niles IR sensors

All IR commands required to control the MRZ-6 can be taught to a learning remote control via the the MRZ-6’s teaching IR flasher . This conveniently integrates control of your source components with control of your MRZ-6. Niles IR sensors relay commands and sequences from the learning remote control to the MRZ-6 and display the status of a room (a green LED lights when the room is on). Niles manufactures a wide range of IR sensors, including in-wall, cabinet-mount, surface-mount, tabletop or even omnidirectional ceiling-mount sensors.

Strain Relief Bar For All Connected Cables

A supplied steel bar attaches to the rear of the MRZ-6. By looping any cable around the strain relief bar before you connect it to the MRZ-6, you relieve all strain on the cables. Now, anytime you move the MRZ, you move the cables too, no more accidental disconnects.

Total Front-Panel Control

The front panel buttons of the MRZ-6 enable you to control ALL ON, ALL OFF, ROOM ON/OFF and VOLUME UP/DOWN. When entertaining family and friends, whole-house volume changes are easy and convenient.

Single, Dual and Multi-Zone Capable

Multiple MRZ-6s can be configured into systems where all rooms listen to the same source or as multiple listen ing zone systems, where each MRZ-6 (up to 6 rooms) is connected to a dedicated source selecting preamp/receiver creating a system where more than one source can be enjoyed simultaneously within the house.

Configurable Power With The Niles SI-1230

The Niles SI-1230 twelve channel amplifier enables you to configure the power for each area, selecting 15 watts per speaker (two speakers in mono fed from one channel), 30 watts per speaker (two speakers in stereo each fed from a dedicated channel) or 80 watts per speaker (two speakers in stereo each fed from a pair of bridged channels).

Compatible With Any Power Amplifier

The MRZ-6 is compatible with any power amplifier. As a result you may configure the power as your needs dictate; a large amplifier for outdoor or critical listening areas and smaller amplifiers for small rooms or background areas.

Easy System Expansion

Up to six MRZ-6’s can be linked to control systems with up to 36 rooms. When linked, Global ALL ON or ALL OFF commands affect the entire system. In addition, connected infrared controlled source equipment may be controlled from any room with an IR sensor or IntelliPad.

Control Output

The 12V DC CONTROLOUT and an optional Niles AC-3 voltage-activated AC power switching system (Niles stock# FG00242) enable your MRZ-6 to turn on and off components which do not have an IR command to turn on and off (CD players, tape decks, power amplifiers etc.).

Confirm and Status LEDs

The CONFIRM LED flashes green when the MRZ-6 receives any IR command. The ROOM STATUS LEDs light green when a room module is turned on. When a green ROOM STATUS LED blinks the corresponding room module is “selected” and ready to be controlled.

Room Identification Labels

Recessed areas above the ROOMSTATUS LEDs and buttons accommodate room identification labels enabling you to custom label each room. Seventy-two adhesive-backed room labels are included with your MRZ-6.

Proudly Made in the USA

The MRZ-6 is made in Miami, Florida and comes with a limited two year parts and labor warranty.

Using The Strain Relief Bar

Introduction — The Purpose of the Strain Relief Bar

The supplied steel bar attaches to the rear of the MRZ-6. By looping any cable around the strain relief bar before you connect it to the MRZ-6, you relieve strain on the cables. Now, anytime you move the MRZ-6, you move the cables too — no more accidental disconnects.

Installing the Strain Relief Bar

Figure 6 Rotate the bar until the ends line up with the two hole on the rear panel of the MRZ-6.

Figure 7 Insert the bar until the bend in the bar prevents any further insertion.

Figure 8 Rotate the bar until the welded stops reach the rear panel of the MRZ-6 and the bar is parallel to the shelf the MRZ-6 is sitting on.

Audio connections

Introduction — The MRZ-6 Has Only One Input

An MRZ-6 has one set (left and right) of line-level inputs. All of the rooms connected to an MRZ-6 listen to the same source. The MRZ-6 cannot switch between two sources (i.e., CD and Tuner) without some kind of outboard input switcher. Typically, the input switching you need is built into a preamp, receiver, or an IR controlled switching device. The two most popular methods of providing the input switching you need for your multi-room system is to either purchase an infrared remote controlled preamp/receiver that is dedicated to the multi-room system or to purchase an infrared remote controlled “two zone” preamp/receiver, using one zone of the preamp/receiver for a home theater and the other zone to select sources for the MRZ-6.

In the following sections, only IR controlled input switching is discussed. This is because of the extensive automation capabilities of the MRZ-6. Using an inexpensive manually controlled switcher for the MRZ-6 will work sonically and electrically, but will not take advantage of the MRZ-6’s automation.

Connections for a System with Only One Source

An MRZ-6 has one set (left and right) of line-level inputs. If you have only one source (i.e., a CD player), its line level outputs may be connected to the MRZ-6’s inputs via a stereo patch cable with RCA phono plugs on both ends. See Figure 9.

Connections for a System with a Dedicated Preamp/Receiver or a Two Zone Preamp/Receiver

All of the source outputs are fed to the preamp/receiver’s inputs, the preamp/receiver selects a source and the output is fed to the MRZ-6 input via a stereo patch cable with RCA phono plugs on both ends. If a “preamp output” is used, the volume control of the preamp/receiver (a master volume for the entire system) must be permanently set to a high level (typically about 12 o’clock or 0dB) and never changed. Alternatively, a “tape output” or “record output” can be used, unless the preamp/receiver incorporates a record output selector switch that does not respond to an infrared remote control for input selection. See Figure 10.

When a two zone preamp/receiver is used, all of the source outputs are fed to the two zone preamp/receiver’s inputs, the home theater or main zone of the preamp/receiver selects a source for the home theater and the second zone preamp of the preamp/receiver selects a source for the multiroom system. The second zone preamp output is fed to the MRZ-6 input via a stereo patch cable with RCA phono plugs on both ends. The volume control of the second zone of the preamp/receiver (the master volume for the entire system) must be permanently set to a high level (typically about 12 o’clock or 0dB) and never changed.

Output Audio Connections to Amplifiers

Every room output is connected to an amplifier channel. The ideal companion is the Niles SI-1230 twelve channel amplifier. A stereo patch cable (with RCA phono plugs on both ends) is connected from each room output to a grouped pair of inputs on the SI-1230. See Figure 11.

Expanding The System With Up To Six MRZ-6’s

In a system with more than six rooms, additional MRZ-6/SI-1230 combinations can be added, to a maximum of six MRZ-6s (36 rooms) so that the ALL ON and ALL OFF commands will work reliably throughout the system. Two types of system design are supported with multiple MRZ-6 units as follows:

Single Zone

— One Master MRZ-6

And Up To Five Slave MRZ-6 Units

The MRZ-6 whose Input is connected to the Preamp/Receiver’s Output is the Master . The cascade output of the Master MRZ-6 is then connected to the input of the Slave MRZ-6. Using the cascade output, each Slave MRZ-6 input is connected to the preceding MRZ-6. All On and All Off commands will work reliably throughout the system. See

Figure 12.

Caution! In A Multiple Zone System With More Than One Master MRZ-6, You Cannot Add Any Slave MRZ-6 Units

Because of the nature of the communication protocol between MRZ-6 units, All On and All Off commands will not work correctly and/or reliably if you attempt to expand one of the multiple Master MRZ-6s (each with its own dedicated preamp/receiver) with an additional Slave MRZ-6.
