Main Features

The AC-90 is a high-performance monitor amp developed exclusively for use with acoustic instruments. It is capable of faithfully expressing all the harmonic richness of an acoustic instruments sound.
Compact, High-Performance Stereo Amp
The finely tuned design of the cabinet is meant to enhance the sound of acoustic instruments. Within this cabinet, there are two 8 inch woofers, two tweeters, and a 45 W + 45 W stereo ampall of which were newly designed just for the AC-90. As a result, the unit is capable of delivering a more natural, acoustic instrument sound across a broad range of frequencies. Thanks to a power amp that was designed to be as light as possible, and the use of new materials for the woofers, an overall reduction in the weight of the unit has been achieved.

Mute Function

The provided Mute switch makes it easy for you to mute the sounds for the AC-90s own speakers as well as the sounds from LINE OUT. By using the Mute function, you can plug in and out noiselessly at the guitar. Furthermore, when you have a tuner connected to TUNER OUT, the Mute function lets you tune your instrument without outputting any sound. You can connect an optional foot switch and use your foot to turn this on and off.
External Input Jacks (AUX IN)
Includes external input jacks, allowing you to connect a CD player, backing machine, or other device in stereo. These include both RCA phono jacks and 1/4 phone jacks, making it possible to connect just about any kind of device.
Features Two Independent Channels, GUITAR and MIC/LINE
Each channel includes a 3-band equalizer. GUITAR channel handles both piezo and magnetic pickups. The MIC/LINE channel offers phantom power, produced by highly reliable, dedicated 48 V output phantom circuitry. Using the MIC/LINE channel for LINE input allows you to connect guitars with magnetic pickups. You can also use a piezo pickup (GUITAR channel) and a magnetic pickup (MIC/LINE channel) at the same time, and mix (blend) the sounds together.
Multiple Output Connectors
Features DI Out, which allow you to directly output the signals input from connected instruments and mics. You can also connect a tuner. TRS balanced output is supported. Line outs feature 1/4 phone mono-output jacks in addition to XLR connectors for stereo output. You can use a single AC-90 for all applications. It also features a Subwoofer Out. Connecting a powered subwoofer allows you to play with an even punchier, more powerful low end. The amp also provides a headphones jack, which you can use when playing during nighttime hours and when making sound checks.

10. CHORUS Buttons

Switch chorus on and off. When on, the indicator is lit.

6. VOLUME Knobs

Adjusts the volume of the GUITAR channel. * To accommodate the lower output of piezo pickups, the volume level when the VOLUME knob is between the 7 and 10 positions is set somewhat higher when the PICKUP button is set to PIEZO in comparison with the MAGNETIC setting. You can use a foot switch (the optional BOSS FS-5U) to switch chorus on and off. Turning chorus on and off with the foot switch works on both channels.

11. CHORUS Knob

Turn this knob to select among the three types of chorus (SPACE, RICH, and WIDE). You can adjust the amount of effect applied by changing the position of the knob. * This is enabled when the CHORUS button is in the ON position. * The markings indicating the SPACE and RICH positions are approximate. Listen to the sound to confirm the effect as you make adjustments.
Adjusts the volume of the MIC/LINE channel. * When using the AC-90 with the GUITAR channel and MIC/ LINE channel mixed, adjust the volume balance between the two channels with the VOLUME knob.

7. BASS Knobs

Adjust the level of the low-frequency range.
This is a spacially synthesized chorus. With spacially synthesized chorus, a method available only in stereo, the chorus effect is created by taking the sound from the right speaker (from which the effect sound is output), and the sound from the left speaker (which outputs the direct sound), and then mixing them in the actual space. This creates a greater lateral spread than that produced when the sounds are mixed electronically, providing a more natural sense of breadth.

8. MIDDLE Knobs

Adjust the level of the midrange.
AC-90_egfispd.book Page 10 Tuesday, May 15, 2007 2:37 PM
This is a stereo chorus that is divided into three frequency ranges. Here, the effect is separated into three bands, low-frequency, midrange, and high-frequency, and by applying the most suitable amount of chorus effect in each range, it provides a sense of fullness and breadth that is perfectly suited to the acoustic guitar. The low end is firmly in the center, and sound spreads out more and more as the sound rises from the midrange up through the higher frequencies.

fig.031

MANUAL
* Turn the knob to OFF if you are not using anti-feedback.

14. START Button

This is used for Auto settings (p. 11). Pressing the button performs automatic detection of feedback-whine frequencies. The indicators show the operating status of the automatic detection function. Standby: Flashes slowly During Detection: Flashes rapidly After Detection: Remains lit * Holding down the START button for one second or longer returns the unit to standby for automatic detection.
While also relying on the division of sound into separate bands, this chorus offers even greater expansiveness than RICH. The sound image spreads beyond the AC-90s speakers, producing an effect that seems to envelope the listener in sound.

12. REVERB/DELAY Knob

You can adjust this knob to switch between the reverb and delay effects. You can adjust the amount of effect applied by changing the position of the knob. * Turn the knob to OFF if you are not using the reverb or delay effect. * The markings indicating the reverb and delay positions are approximate. Listen to the sound to confirm the effect as you make adjustments.

How to Use ANTI-FEEDBACK

fig.32
Anti-feedback is a function that controls feedback that arises between the guitar or mic and the amp. The feedback is suppressed by attenuating the frequency at which the feedback occurs. * This is not designed to work with respect to the high-frequency feedback that can occur when using microphones. Anti-feedback can be used in two different ways; you can make use of either the Auto settings or the Manual settings. * Use either when feedback whine occurs. Feedback This is a phenomenon whereby signals output from the speakers are picked up again by the mic or pickup, and the sound is further amplified and output from the speakers, resulting in an unpleasant oscillating sound. * If the anti-feedback alone does not control the feedback, adjust your settings, for example by lowering the volume or cutting the low frequencies. * To prevent feedback during a performance, we recommend making the anti-feedback setting before the performance.

REVERB

This stereo reverb, developed especially for acoustic instruments, gives a sense of spaciousness and natural sonic quality. Turn the knob to adjust the volume of the reverb effect.
This delay, developed especially for acoustic instruments, adds soft reflections to the original sound. Turn the knob to change the delay time. * You can use a foot switch (the optional BOSS FS-5U) to switch the reverb and delay on and off.

13. FREQUENCY Knob

This selects the frequency at which the anti-feedback function operates. Also, the position of the knob determines whether Auto or Manual settings are selected.
AC-90_egfispd.book Page 11 Tuesday, May 15, 2007 2:37 PM
Setting the Feedback Point Automatically
This automatically detects the frequency at which feedback occurs and suppresses feedback. * Use in conditions where feedback occurs. 1. Cause feedback whine to occur. 2. Turn the FREQUENCY knob to the AUTO position.

fig.033

15. MUTE Button
When you press the button, the MUTE indicator flashes, muting is turned on, and the speaker output and sounds from SUB WOOFER OUT and LINE OUT are muted. With the mute function activated, you do not need to turn down the VOLUME knob or MASTER knob to mute the noise when plugging into, or unplugging from your guitar. * Sounds from the DI OUT/TUNER OUT and PHONES jacks are not muted.

Reverb/Delay On/Off

1. LINE OUT Jacks

You can connect a mixer, recording device, or other device here. The output level is +4 dBu. Included here are XLR connectors (L/R: stereo output) and a 1/4 phone jack (mono output).

fig.090

2. SUB WOOFER OUT Jack
You can connect a powered subwoofer to play back sounds with an even punchier, more powerful low end. The volume is adjusted with the MASTER knob.

3. AUX IN Jacks

You can connect a CD player, drum machine, or other device and play back sounds in stereo. Both RCA phono jacks and 1/4 phone jacks are provided. When connected to only the left 1/4 phone jack, playback is in mono. Although the input from AUX IN is output from the speakers, PHONES, and SUB WOOFER OUT, it is not output from LINE OUT. The volume is adjusted with the MASTER knob, and muting on/off for these sounds is controlled with
* You cannot adjust the volume for LINE OUT with the MASTER knob. * The chorus effects are designed so they exhibit the greatest effectiveness when you use the units built-in speakers. Effectiveness may differ when LINE OUT is used instead of the built-in speakers.
AC-90_egfispd.book Page 13 Tuesday, May 15, 2007 2:37 PM
the MUTE button. If devices are connected to both the RCA phono jacks and the 1/4 phone jacks, the two inputs are mixed.

(MUTE, ANTI-FEEDBACK)

Connecting a foot switch pedal (optional BOSS FS-5L, FS-5U, or FS-6) using a connection cable (the optional PCS-31) makes it possible to use a latch-type foot switch (the FS-5L or FS-6) to switch muting on and off, or to use a momentary-type foot switch (the FS-5U or FS-6) to control the anti-feedback feature. * For information on the settings for the FS-6, refer to the owners manual for the FS-6.

fig.050

4. DI OUT/TUNER OUT Jack
The direct sound of the device or instrument connected to the GUITAR or MIC/LINE channel is output here. This is a 1/4 phone TRS jack with balanced output. You can also use this jack to connect a tuner.

fig.070

* If balanced output is not required, use a 1/4 phone (mono) plug to connect to this jack.

If balanced output is not required, you can use the special connection cable (the optional PCS-31) to use the DI OUT and TUNER OUT simultaneously.

fig.080

* The MUTE button should be set to off when a foot switch is connected for muting. You cannot switch the muting off by pressing the foot switch when the MUTE button is on (when the MUTE indicator is lit). * When using an FS-5U (momentary type) to switch muting on and off, the muting is switched on only while the switch is held down. For anti-feedback, a foot switch will function as follows: When the FREQUENCY knob is positioned in the range from L to H, the switch turns the anti-feedback function on and off. When the FREQUENCY knob is positioned at AUTO, the switch functions as the START switch for the automatic detection. Holding the foot switch down for one second or longer returns the automatic detection function to standby mode.

Tuner Recoreder

A phase-inverted signal is output from the COLD side (the red side of the PCS-31). Connect the recording device to the HOT side (the white side of the PCS-31)

5. FOOT SW Jacks

The AC-90 accepts the BOSS FS-5L (latch type), BOSS FS-5U (momentary type), and BOSS FS-6 foot switch pedals. * Set the polarity switch as shown below.

fig.071

Using a special connection cable (the optional PCS-31) to connect two foot switches (the optional BOSS FS-5U), you can use one FS-5U to switch the chorus on and off, and use the other FS-5U to switch the delay or reverb on and off.

fig.060

When a 1/4 phone (mono) plug is used to connect only one foot switch, only the chorus on/off function is enabled. * The chorus on/off function works on both channels. * You cannot switch the chorus on and off by pressing the foot switch when the CHORUS button is off.

(CHORUS, DELAY/REVERB)

When a 1/4 phone (mono) plug is used to connect only one foot switch, only the Mute on/off function is enabled. In such cases, you should use a latch-type foot switch pedal (such as the BOSS FS-5L)

ROLAND ANNOUNCES AC-90 ACOUSTIC GUITAR PERFORMANCE AMP
Austin, TX, July 27, 2007Building on the popularity of the AC-60 Acoustic Guitar Amp, Roland announces the AC-90 Acoustic Guitar Amp. With 8-inch Neodymium speakers and a two-way speaker system for crystal clear highs and a punchy low-range, the AC-90 provides a powerful acoustic sound in a lightweight, easy to carry package. Roland Division Manager Peter Swiadon relates, The AC-90 is perfect for the solo artist or the guitarist in an ensemble act where acoustic guitar sounds often get lost or overpowered by other instruments. This new amp punches up the acoustic guitar presence on a small stage, or in an arena. Additional features include an impressive automatic Anti-feedback function, two independent channels-one with an XLR input and phantom power, Reverb/Delay for each channel, stereo multi-band chorus, a convenient on-board tilt stand and a durable carrying bag. The new AC-90 mounts easily onto any standard speaker stand.
