INTRODUCTION
Thank You for purchasing the Sonamp® 1230. Sonance has taken the versatile Sonamp® 1250 and improved it by adding more features, which makes the Sonamp® 1230 the most versatile and reliable multi-channel amplifier available. Most importantly, we listened to installers and end users and added features that they wanted.
ADDITIONAL AMPLIFIERS
If additional Sonamp® 1230's are used, we recommend separate 15 amp circuits for each amplifier due to the enormous power capability and requirements of this product. Non-buffered LINE OUT connections for left, right, and auxiliary channels are provided. Within the limits of available mains power, any number of additional Sonamp 1230 amplifiers may be daisy chained for larger installations.
ASSOCIATED COMPONENTS
A music reproduction system is only as good as its weakest link. To avoid disappointment, your Sonamp® 1230 should be used with other components of the highest caliber. The Sonamp® 1230 is compatible with most high quality preamplifiers, tuners, CD/DVD players, and Mini Disc decks; as well as better in-wall and cabinet mounted speakers from Sonance and other reputable manufacturers.
CARE AND MAINTENANCE
Retain the safety and operating instructions for future reference.
1.Follow all warnings and instructions in this manual and marked on the product.
2.Any service or repair required must be performed by qualified, factory authorized personnel.
3.To clean your Sonamp 1230, use a soft brush,“canned air,”or wipe exterior surfaces with a damp cloth. Never use any cleaners or solvents.
4.Do not use this product in a high humidity environment or near water, for example a wet basement, wet bar, or swimming pool.
5.If the electrical service is subject to frequent sags, spikes, and brownouts, a power conditioner designed for use with high fidelity equipment may be employed to protect the Sonamp 1230.
SYSTEM CONFIGURATION
Read Getting The Most From Your Sonamp 1230 and plan your installation configuration. Due to the flexibility of the Sonamp 1230, the installation should be carefully planned to avoid errors.
Start by drawing a diagram of the system,like the examples in this manual.Plan the settings and connections to achieve your objective.
Verify that you have all of the parts and tools required for the installation:
• High fidelity interconnect cables such as Sonance Silver MediaLinQ OFC Interconnects.
•Speaker wires. These may be unterminated (tinned bare wire at connections) or spade, banana, or pin connectors. Gold plated connectors are preferred to resist oxidation.
•LS1 and LR1 balanced line-level sender and receiver (optional). If the amplifier is placed more than 20 feet from the source or preamplifier, the balanced sender and receiver provide a way to send low level audio signals long distances and near sources of noise interference without introducing noise or suffering high frequency roll-off (See Fig. 6 for example).
INSTALLATION
Unpacking
Save the carton and polystyrene inserts for future safe transport in case the amplifier is moved or the unit requires shipping for repair.
Before proceeding with installation, locate the serial number on the real panel of the unit and note it here for future reference :
S/N:_________________________________________
Placement
CAUTION: Do not attempt to lift the Sonamp 1230 without assistance. Improper lifting of this 35 lb. unit can cause personal injury.
Place the Sonamp® 1230 on a level surface, in an upright position, out of direct sunlight and away from windows through which rain may enter.NOTE: The amplifier must always rest on its four feet to allow ventilation or it will sustain damage.
Situate the amplifier away from heat sources such as hot air ducts or radiators. Be sure that the amplifier is adequately ventilated by convection or suitable cabinet fans. CAUTION: The Sonamp® 1230 requires four inches of clearance on the top and all sides. Never place any object on or against the amplifier. Never operate the amplifier on a carpeted surface as this will compromise ventilation. When the amplifier is installed in any cabinet, the front or back must be open during operation. Alternately, install fans in the cabinet to assure continuous ventilation.
Power Connection
The Sonamp® 1230 uses a 14 gauge EIA standard 120 volt grounded power cable (provided). Due to the power requirement of this amplifier, it is not advised that this cable be replaced with another of unknown quality.Connect the power cable to a 15 amp or 20 amp grounded wall outlet.Never attempt to operate the amplifier from the accessory outlet of another component.
Sensitive source components should be isolated from the Sonamp® 1230 with appropriate power conditioning to minimize hum from the amplifier’s power supply.
Speaker Connection
Always turn off power and unplug the amplifier before making source signal or speaker connections.
Use quality speaker wire such as Sonance Silver or Gold

MediaLinQ™ cable to assure optimum sound reproduction. Small gauge or inferior quality wire will degrade imaging, diminish bass reproduction, and add a generally congested quality to music. Always check local building codes before installing wire in walls or ceilings.
Wires may be terminated with banana plugs for convenience if connections will be changed frequently. Any connector should be gold plated to prevent oxidation, which degrades sound quality. The binding posts on the Sonamp® 1230 also accept twisted bare wire ends through the 45º opening in their center shafts. Do not overtighten shafts. Tinning the bare copper wire is recommended. As an option, use contact enhancer on mating surfaces of connections to retard oxidation and enhance signal flow. Do not strip more than 1/2”of the jacket from speaker wires.
Always provide sufficient slack in wires to avoid tension or accidental disconnection. Always contain any excess wire to prevent tripping hazards.
Source Connection
Always use quality high fidelity interconnect cables such as Sonance Silver MediaLinQ OFC Interconnects. If source components are more than 20 feet from the amplifier, use the LS1 and LR1 balanced line-level sender and receiver to avoid signal degradation (As shown in Figure 6).
Plug source components (receiver, preamp, page signal) to the LINE IN bus inputs at the top center of the amplifier.
Plug dedicated sources (zone output, page signal, video game, or electronic doorbell) into the DIR (direct) channel inputs if desired.
Plug downstream amplifiers to the non-buffered LINE OUT bus outputs at the bottom center of the amplifier.
Source Settings
The fourplex DIP switches of the Sonamp® 1230 provides the most flexible configuration options of any multichannel amplifier. Settings are changed by moving the switches from (ON) to (OFF):
L |
Assign to master left channel source |
R |
Assign to master right channel source |
L + R |
Mono reproduction of source |
AUX |
Assign to AUX channel source |
DIR |
Select dedicated channel input. |
Note: It is possible to assign one or all switches as needed (L+R+AUX, where AUX is the page input for a hallway or waiting room with paging.
Volume Control
The individual channel volume controls are useful to balance the desired sound levels for various zones, to balance output from right and left channels to compensate for room characteristics such as size and ceiling height.Also,by reducing the Sonamp volume control settings, you compel the source preamp or receiver volume control to operate in the middle of its range. do not set the level controls higher than the maximum level desired. Place tape over the VC hole to prevent tampering.
Power Trigger Controls
The Sonamp® 1230 may be automatically activated by an input signal, low voltage trigger, or manual pushbutton. It also provides a 12 volt DC output to trigger other components.
Auto-On Control
To use the Auto-On feature, turn the main power switch ON and slide the TRIGGER switch on the rear panel to the UP position. Use the SENSITIVITY control to set the minimum signal level that will activate the amplifier. In this mode, the amplifier will automatically turn off after 8 minutes of no input signal at any of the 12 channel inputs. The Auto-On mode disables the other two triggering modes.
Voltage Control
When the TRIGGER switch is set to EXTERNAL VOLTAGE (the center position) and the main power switch (on the front panel) is set to ON, the amplifier will be activated by the presence of AC or DC voltage, from 5 to 24 volts, at the INPUT connector. The EXTERNAL VOLTAGE mode disables the other two triggering modes. (DO NOT CONNECT TO 120VAC LINE VOLTAGE)
Bypass
If the TRIGGER switch is set to BYPASS (the bottom position) and the main power switch (on the front panel) is set to ON, the amplifier will always be active. The BYPASS mode disables the other two triggering modes.
Ground lift
The GROUND LIFT switch breaks ground loops that can occur between source equipment and amplifiers. Set the GROUND LIFT switch to OFF for most applications. When the Sonamp 1230 is to be used in an equipment rack, set the GROUND LIFT switch in the ON position. This will isolate the audio circuitry from the chassis. Thus, the chassis need not be isolated from the equipment rack with insulator washers.
Status LEDs
AC ON LED – This red LED indicates that the AC power line cord is plugged into a live AC outlet. If the main AC line fuse opens, this LED goes out. The main power switch setting does not impact this LED.
ACTIVE LED – This green LED indicates that the amplifier has been activated via one of the three methods described previously.
PROTECTION LEDs – These amber LED’s light during a fault condition, one LED for each pair of channels. If one of the Sonamp 1230’s protection circuits is triggered, the LED will turn on. If a channel pair encounters a short-circuit event or an extremely low impedance, the respective LEDs will light (1&2, 3&4, 5&6, 7&8, 9&10, 11&12). All other channel pairs are unaffected. If the heat sink temperature is exceeded because of poor air circulation or high ambient temperature, a cutoff switch attached to left and right channels will activate. Each bank (1&2, 3&4, 5&6 or 7&8, 9&10, 11&12)of a Protect LEDs will then light to signify a fault. If amplifiers are in Bridged mode, the Protection Circuitry will sense a short circuit across both positive speaker terminals and also positive to negative speaker terminal.
