FEATURES
Marantz has surpassed itself with the new PM-15S1 stereo integrated amplifier, which incorporates many of the design concepts of the PM-11S1 flagship model amplifier.
Amplifier
• HDAM SA2
As in the PM-11S1 model, the PM-15S1 also incorporates the HDAM SA2 as the main amp module. The HDAM SA2 includes an input buffer, linear control volume and power buffer.
Power
• Power Transformers
Newly developed Toroidal power transformers are used in the PM-15S1 because they produce less vibration and magnetic leak than ordinary laminate design transformers. Vibration reduction is achieved by using ring shaped core materials, while rigorous controls are maintained on the manufacturing process. Furthermore, the transformer periphery is covered with a ring core and short ring to reduce magnetic flux leak.
• Linear Control Volume
PM-15S1 inherits the Linear Control Volume system used in the PM-11S1, which offers smooth volume control of ±0.5dB steps in a range of 0dB - 100dB.
• Current Feedback Phono Equalizer
The Phono Equalizer, which has MM/MC type cartridge support, also inherits the Current Feedback Phone Equalizer used in PM-11S1.
• Input Buffer
The input buffer is composed of the HDAM SA2 in the input section, which enables signals from the input source to be transmitted precisely to the linear control volume.
• Power Amplifier
Following closely in the footsteps of its predecessor, the PM11S1 is designed using a two-amplifier construction. By using a two-amplifier system, the power buffer uses high power to drive the speakers, therefore cutting the effects of Back EMF from the speakers.
• LC Ripple Filter
An LC Ripple Filter has been incorporated into the pre-amp power circuit, which provides “clean” power to the pre-amp section. “Clean” power is achieved by cutting out rectifier noise generated by the rectifier circuit, as well as external high frequency noise.
Functions
• Bi-Amp Mode
The complete bi-amp connection proposed by Marantz with the SC-7S1 and MA-9S1 reproduces a sound environment never before experienced. This same bi-amp connection has been made possible with the PM-15S1. Two PM-15S1s are connected by F.C.B.S. in a bi-amp mode that enables each to work as a monaural integrated amplifier.
• Floating Control Bus System
A Floating Control Bus System (FCBS) enables the user to connect up to four PM-15S1s, making possible a diversity of applications with complete bi-amp and multiple channel connections.(pg. 6, 7) Moreover, a ground loop is not formed between multiple connected PM-15S1s, therefore sound quality is not adversely affected.
• Display
The PM-15S1 adopts an LCD to display input source and volume level. Compared to other types of display panels, an LCD generates less drive noise and radiated noise, hence the effect on sound quality is minimal.

Your speaker system must satisfy the below conditions. If it does not, the PM-15S1’s protective circuit will trip, whereby preventing proper playback. In some cases, the amplifier and speakers may be damaged.
•If using 1 set of speakers, total speaker impedance must be 4Ω or more.
•If using 2 sets of speakers, total speaker impedance must be 8Ω or more.
BI-WIRING CONNECTION
A bi-wiring connection separately connects the low and mid/ high jacks of the speaker to the amplifier using separate speaker cables. Because separate cables are used for low and mid/high sounds, the return current generated in the low speaker causes little interference with the mid/high speaker. The PM-15S1 and speakers of Connection Example 1 (pg. 5) use a bi-wiring connection, therefore also refer to that page for help.

COMPLETE BI-AMP CONNECTION
Proposed by Marantz, the complete bi-amp connection enhances the bi-wiring connection. With it, the low and mid/high amplifiers are separate and independent of the preamplifier, therefore interference between low and mid/high sounds is reduced to a minimum. As a result, a wide sound environment can be reproduced. Connection Example 3 (pg. 7) connects two PM-15S1s by FCBS in a complete bi-amp connection, therefore also refer to that page for help.

BEFORE MAKING CONNECTIONS
SPEAKER POSITIONING FOR SUPER AUDIO MULTI-CHANNEL SOUND
In order to enjoy Super Audio CD multi-channel sound with the best possible acoustics, it is recommended to position speakers as specified in ITU-R BS.775-1 of the International Telecommunication Union (ITU). Super Audio CD multi-chan- nel discs are recorded and mixed so as to achieve the optimum effect with a speaker system laid out as specified in ITU- R BS.775-1.
•With Super Audio CD multi-channel discs, the music signals are basically recorded using 5 channels (3 - 6 channels sometimes), but in some cases, LFE (for subwoofer) is recorded as a sixth channel. Each disc indicates how many channels have been recorded on it.
•The basic layout is 3 speakers in the front and 2 in the back since multi-channel discs usually have 5 channels. The 2 front, 1 center and 2 surround (rear) speakers should be set in a circle around the listening point as shown below. If using speakers of differing sizes, adjust volume balance from the amplifier.
•The location of the subwoofer in the figure is just for explanatory purposes. It can be located anywhere in the room. For connection and positioning instructions, see the instruction manual that came with the subwoofer.
7 ITU (International Telecommuni-
cation Union)
The ITU is a special organization of the United Nations. It consists of a number of organs, one of which is the Radio Broadcasting Section.
ITU-R BS in the recommendation which consists of standards relating to broadcasting (audio) operations, one of which is the ITU-R BS.775-1 which governs “multi-channel stereo sound systems.”
